  text: Developing cost-effective and high-performance thermoelectric (TE) materials
    to assemble efficient TE devices presents a multitude of challenges and opportunities.
    Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant
    elements. However, the challenge lies in its poor electrical conductivity. Herein,
    an efficient and scalable solution-based approach is developed to synthesize high-quality
    Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement
    and annealing treatments, the dried powders are consolidated into dense pellets,
    and their TE properties are investigated. Pb doping effectively increases the
    charge carrier concentration, resulting in a significant increase in electrical
    conductivity, while the Seebeck coefficients remain consistently high. The calculated
    band structure shows that Pb doping induces band convergence, thereby increasing
    the effective mass. Furthermore, the large ionic radius of Pb2+ results in the
    generation of additional point and plane defects and interphases, dramatically
    enhancing phonon scattering, which significantly decreases the lattice thermal
    conductivity at high temperatures. Overall, a maximum figure of merit (zTmax)
    ≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold
    increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based
    materials produced by solid-state, demonstrating advantages of versatility and
    cost-effectiveness using a solution-based technology.

  text: AgSbSe2 is a promising thermoelectric (TE) p-type material for applications
    in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal
    conductivities and high Seebeck coefficients, but its main limitation is moderate
    electrical conductivity. Herein, we detail an efficient and scalable hot-injection
    synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier
    concentration and improve the electrical conductivity, these NCs are doped with
    Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using
    a reducing NaBH4 solution to displace the organic ligand and anneal the material
    under a forming gas flow. The TE properties of the dense materials obtained from
    the consolidation of the NCs using a hot pressing are then characterized. The
    presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier
    concentration and, consequently, the electrical conductivity. Opportunely, the
    measured Seebeck coefficient varied within a small range upon Sn doping. The excellent
    performance obtained when Sn2+ ions are prevented from oxidation is rationalized
    by modeling the system. Calculated band structures disclosed that Sn doping induces
    convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic
    effective mass. The dramatically enhanced carrier transport leads to a maximized
    power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon
    scattering is significantly enhanced in the NC-based materials, yielding an ultralow
    thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of
    merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above
    the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and
    Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate
    for medium-temperature TE applications.

  text: Cu2–xS and Cu2–xSe have recently been reported as promising thermoelectric
    (TE) materials for medium-temperature applications. In contrast, Cu2–xTe, another
    member of the copper chalcogenide family, typically exhibits low Seebeck coefficients
    that limit its potential to achieve a superior thermoelectric figure of merit,
    zT, particularly in the low-temperature range where this material could be effective.
    To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites
    by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering
    strategy allows for precise adjustment of Cu/Te ratios and results in a reversible
    phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically
    confirmed by in situ high-temperature X-ray diffraction combined with differential
    scanning calorimetry analysis. The phase transition leads to a conversion from
    metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se
    generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain
    growth, minimizing thermal conductivity and decreasing hole concentration. These
    properties indicate that copper telluride based compounds have a promising thermoelectric
    potential, translated into a high dimensionless zT of 1.3 at 560 K.

  text: 'The broad implementation of thermoelectricity requires high-performance and
    low-cost materials. One possibility is employing surfactant-free solution synthesis
    to produce nanopowders. We propose the strategy of functionalizing “naked” particles’
    surface by inorganic molecules to control the nanostructure and, consequently,
    thermoelectric performance. In particular, we use bismuth thiolates to functionalize
    surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates
    decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1)
    carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement
    and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity
    reduction by small grain domains, grain boundaries and nanostructuration. Overall,
    the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average
    z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed
    SnTe.'

  text: SnSe has emerged as one of the most promising materials for thermoelectric
    energy conversion due to its extraordinary performance in its single-crystal form
    and its low-cost constituent elements. However, to achieve an economic impact,
    the polycrystalline counterpart needs to replicate the performance of the single
    crystal. Herein, we optimize the thermoelectric performance of polycrystalline
    SnSe produced by consolidating solution-processed and surface-engineered SnSe
    particles. In particular, the SnSe particles are coated with CdSe molecular complexes
    that crystallize during the sintering process, forming CdSe nanoparticles. The
    presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation
    step due to Zener pinning, yielding a material with a high density of grain boundaries.
    Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects
    at different length scales, which significantly reduce the thermal conductivity.
    The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit
    up to 2.2 at 786 K, which is among the highest reported for solution-processed
    SnSe.

  text: A versatile, scalable, room temperature and surfactant-free route for the
    synthesis of metal chalcogenide nanoparticles in aqueous solution is detailed
    here for the production of PbS and Cu-doped PbS nanoparticles. Subsequently, nanoparticles
    are annealed in a reducing atmosphere to remove surface oxide, and consolidated
    into dense polycrystalline materials by means of spark plasma sintering. By characterizing
    the transport properties of the sintered material, we observe the annealing step
    and the incorporation of Cu to play a key role in promoting the thermoelectric
    performance of PbS. The presence of Cu allows improving the electrical conductivity
    by increasing the charge carrier concentration and simultaneously maintaining
    a large charge carrier mobility, which overall translates into record power factors
    at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity
    decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room
    temperature and ZT = 1.22 at 773 K. Besides, a record average ZTave = 0.76 is
    demonstrated in the temperature range 320–773 K for n-type Pb0.955Cu0.045S.

  text: Thermoelectric materials are engines that convert heat into an electrical
    current. Intuitively, the efficiency of this process depends on how many electrons
    (charge carriers) can move and how easily they do so, how much energy those moving
    electrons transport, and how easily the temperature gradient is maintained. In
    terms of material properties, an excellent thermoelectric material requires a
    high electrical conductivity σ, a high Seebeck coefficient S (a measure of the
    induced thermoelectric voltage as a function of temperature gradient), and a low
    thermal conductivity κ. The challenge is that these three properties are strongly
    interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury
    et al. (2) have found a way to partially break these ties in silver antimony telluride
    (AgSbTe2) with the addition of cadmium (Cd) cations, which increase the ordering
    in this inherently disordered thermoelectric material.

  text: The cost-effective conversion of low-grade heat into electricity using thermoelectric
    devices requires developing alternative materials and material processing technologies
    able to reduce the currently high device manufacturing costs. In this direction,
    thermoelectric materials that do not rely on rare or toxic elements such as tellurium
    or lead need to be produced using high-throughput technologies not involving high
    temperatures and long processes. Bi2Se3 is an obvious possible Te-free alternative
    to Bi2Te3 for ambient temperature thermoelectric applications, but its performance
    is still low for practical applications, and additional efforts toward finding
    proper dopants are required. Here, we report a scalable method to produce Bi2Se3
    nanosheets at low synthesis temperatures. We studied the influence of different
    dopants on the thermoelectric properties of this material. Among the elements
    tested, we demonstrated that Sn doping resulted in the best performance. Sn incorporation
    resulted in a significant improvement to the Bi2Se3 Seebeck coefficient and a
    reduction in the thermal conductivity in the direction of the hot-press axis,
    resulting in an overall 60% improvement in the thermoelectric figure of merit
    of Bi2Se3.

  text: Cesium lead halides have intrinsically unstable crystal lattices and easily
    transform within perovskite and nonperovskite structures. In this work, we explore
    the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS
    at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6
    nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into
    the PbS lattice with a consequent increase in the concentration of free charge
    carriers. This new doping strategy enables the adjustment of the density of charge
    carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for
    doping other nanocrystal-based semiconductors.

  text: 'The precise engineering of thermoelectric materials using nanocrystals as
    their building blocks has proven to be an excellent strategy to increase energy
    conversion efficiency. Here we present a synthetic route to produce Sb-doped PbS
    colloidal nanoparticles. These nanoparticles are then consolidated into nanocrystalline
    PbS:Sb using spark plasma sintering. We demonstrate that the introduction of Sb
    significantly influences the size, geometry, crystal lattice and especially the
    carrier concentration of PbS. The increase of charge carrier concentration achieved
    with the introduction of Sb translates into an increase of the electrical and
    thermal conductivities and a decrease of the Seebeck coefficient. Overall, PbS:Sb
    nanomaterial were characterized by two-fold higher thermoelectric figures of merit
    than undoped PbS. '

  text: Cu2–xS has become one of the most promising thermoelectric materials for application
    in the middle-high temperature range. Its advantages include the abundance, low
    cost, and safety of its elements and a high performance at relatively elevated
    temperatures. However, stability issues limit its operation current and temperature,
    thus calling for the optimization of the material performance in the middle temperature
    range. Here, we present a synthetic protocol for large scale production of covellite
    CuS nanoparticles at ambient temperature and atmosphere, and using water as a
    solvent. The crystal phase and stoichiometry of the particles are afterward tuned
    through an annealing process at a moderate temperature under inert or reducing
    atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral
    crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal
    Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed
    in argon to transform to the cubic phase at ca. 400 K, while the material annealed
    in the presence of hydrogen undergoes two phase transitions, first to hexagonal
    and then to the cubic structure. The annealing atmosphere, temperature, and time
    allow adjustment of the density of copper vacancies and thus tuning of the charge
    carrier concentration and material transport properties. In this direction, the
    material annealed under Ar is characterized by higher electrical conductivities
    but lower Seebeck coefficients than the material annealed in the presence of hydrogen.
    By optimizing the charge carrier concentration through the annealing time, Cu2–xS
    with record figures of merit in the middle temperature range, up to 1.41 at 710
    K, is obtained. We finally demonstrate that this strategy, based on a low-cost
    and scalable solution synthesis process, is also suitable for the production of
    high performance Cu2–xS layers using high throughput and cost-effective printing
    technologies.

  text: The high processing cost, poor mechanical properties and moderate performance
    of Bi2Te3–based alloys used in thermoelectric devices limit the cost-effectiveness
    of this energy conversion technology. Towards solving these current challenges,
    in the present work, we detail a low temperature solution-based approach to produce
    Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach
    consists in combining proper ratios of colloidal nanoparticles and to consolidate
    the resulting mixture into nanocomposites using a hot press. The transport properties
    of the nanocomposites are characterized and compared with those of pure Bi2Te3
    nanomaterials obtained following the same procedure. In contrast with most previous
    works, the presence of Cu2-xTe nanodomains does not result in a significant reduction
    of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which
    is already very low. However, the introduction of Cu2-xTe yields a nearly threefold
    increase of the power factor associated to a simultaneous increase of the Seebeck
    coefficient and electrical conductivity at temperatures above 400 K. Taking into
    account the band alignment of the two materials, we rationalize this increase
    by considering that Cu2-xTe nanostructures, with a relatively low electron affinity,
    are able to inject electrons into Bi2Te3, enhancing in this way its electrical
    conductivity. The simultaneous increase of the Seebeck coefficient is related
    to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains
    associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3
    heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe
    nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure
    of merit of Bi2Te3.

  text: Copper chalcogenides are outstanding thermoelectric materials for applications
    in the medium-high temperature range. Among different chalcogenides, while Cu2−xSe
    is characterized by higher thermoelectric figures of merit, Cu2−xS provides advantages
    in terms of low cost and element abundance. In the present work, we investigate
    the effect of different dopants to enhance the Cu2−xS performance and also its
    thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest
    improvement in stability against sulfur volatilization. Additionally, Pb incorporation
    allows tuning charge carrier concentration, which enables a significant improvement
    of the power factor. We demonstrate here that the introduction of an optimal additive
    amount of just 0.3% results in a threefold increase of the power factor in the
    middle-temperature range (500–800 K) and a record dimensionless thermoelectric
    figure of merit above 2 at 880 K.

  text: Solution synthesis of particles emerged as an alternative to prepare thermoelectric
    materials with less demanding processing conditions than conventional solid-state
    synthetic methods. However, solution synthesis generally involves the presence
    of additional molecules or ions belonging to the precursors or added to enable
    solubility and/or regulate nucleation and growth. These molecules or ions can
    end up in the particles as surface adsorbates and interfere in the material properties.
    This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically
    adsorbed in SnSe particles synthesized in water and play a crucial role not only
    in directing the material nano/microstructure but also in determining the transport
    properties of the consolidated material. In dense pellets prepared by sintering
    SnSe particles, Na remains within the crystal lattice as dopant, in dislocations,
    precipitates, and forming grain boundary complexions. These results highlight
    the importance of considering all the possible unintentional impurities to establish
    proper structure-property relationships and control material properties in solution-processed
    thermoelectric materials.

  text: Composite materials offer numerous advantages in a wide range of applications,
    including thermoelectrics. Here, semiconductor–metal composites are produced by
    just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
    and at room temperature with a metallic Cu powder. The obtained blend is annealed
    in a reducing atmosphere and afterward consolidated into dense polycrystalline
    pellets through spark plasma sintering (SPS). We observe that, during the annealing
    process, the presence of metallic copper activates a partial reduction of the
    PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
    lead during the SPS process habilitates the liquid-phase sintering of the composite.
    Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
    and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
    that the presence of metallic lead decisively contributes to a strong increase
    of the charge carrier concentration through spillover of charge carriers enabled
    by the low work function of lead. The increase in charge carrier concentration
    translates into much higher electrical conductivities and moderately lower Seebeck
    coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
    at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
    the presence of multiple phases in the final composite results in a notable decrease
    in the lattice thermal conductivity. Overall, the introduction of metallic copper
    in the initial blend results in a significant improvement of the thermoelectric
    performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
    = 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
    an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.

  text: In the present work, we report a solution-based strategy to produce crystallographically
    textured SnSe bulk nanomaterials and printed layers with optimized thermoelectric
    performance in the direction normal to the substrate. Our strategy is based on
    the formulation of a molecular precursor that can be continuously decomposed to
    produce a SnSe powder or printed into predefined patterns. The precursor formulation
    and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates.
    The printed layer and the bulk material obtained after hot press displays a clear
    preferential orientation of the crystallographic domains, resulting in an ultralow
    thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate.
    Such textured nanomaterials present highly anisotropic properties with the best
    thermoelectric performance in plane, i.e., in the directions parallel to the substrate,
    which coincide with the crystallographic bc plane of SnSe. This is an unfortunate
    characteristic because thermoelectric devices are designed to create/harvest temperature
    gradients in the direction normal to the substrate. We further demonstrate that
    this limitation can be overcome with the introduction of small amounts of tellurium
    in the precursor. The presence of tellurium allows one to reduce the band gap
    and increase both the charge carrier concentration and the mobility, especially
    the cross plane, with a minimal decrease of the Seebeck coefficient. These effects
    translate into record out of plane ZT values at 800 K.

  text: "Appropriately designed nanocomposites allow improving the thermoelectric
    performance by several mechanisms, including phonon scattering, modulation doping
    and energy filtering, while additionally promoting better mechanical properties
    than those of crystalline materials. Here, a strategy for producing Bi2Te3–Cu2xTe
    nanocomposites based on the consolidation of heterostructured nanoparticles is
    described and the thermoelectric properties of the obtained materials are investigated.
    We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures,
    based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires.
    We characterize the structural and chemical properties of the synthesized nanostructures
    and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate
    temperatures. Besides, the transport properties of the nanocomposites are investigated
    as a function of the amount of Cu introduced. Overall, the presence of Cu decreases
    the material thermal conductivity through promotion of phonon scattering, modulates
    the charge carrier concentration through electron spillover, and increases the
    Seebeck coefficient through filtering of charge carriers at energy barriers. These
    effects result in an improvement of over 50% of the thermoelectric figure of merit
    of Bi2Te3."

  text: Nanomaterials produced from the bottom-up assembly of nanocrystals may incorporate
    ∼1020–1021 cm–3 not fully coordinated surface atoms, i.e., ∼1020–1021 cm–3 potential
    donor or acceptor states that can strongly affect transport properties. Therefore,
    to exploit the full potential of nanocrystal building blocks to produce functional
    nanomaterials and thin films, a proper control of their surface chemistry is required.
    Here, we analyze how the ligand stripping procedure influences the charge and
    heat transport properties of sintered PbSe nanomaterials produced from the bottom-up
    assembly of colloidal PbSe nanocrystals. First, we show that the removal of the
    native organic ligands by thermal decomposition in an inert atmosphere leaves
    relatively large amounts of carbon at the crystal interfaces. This carbon blocks
    crystal growth during consolidation and at the same time hampers charge and heat
    transport through the final nanomaterial. Second, we demonstrate that, by stripping
    ligands from the nanocrystal surface before consolidation, nanomaterials with
    larger crystal domains, lower porosity, and higher charge carrier concentrations
    are obtained, thus resulting in nanomaterials with higher electrical and thermal
    conductivities. In addition, the ligand displacement leaves the nanocrystal surface
    unprotected, facilitating oxidation and chalcogen evaporation. The influence of
    the ligand displacement on the nanomaterial charge transport properties is rationalized
    here using a two-band model based on the standard Boltzmann transport equation
    with the relaxation time approximation. Finally, we present an application of
    the produced functional nanomaterials by modeling, fabricating, and testing a
    simple PbSe-based thermoelectric device with a ring geometry.

  text: Methodologies that involve the use of nanoparticles as “artificial atoms”
    to rationally build materials in a bottom-up fashion are particularly well-suited
    to control the matter at the nanoscale. Colloidal synthetic routes allow for an
    exquisite control over such “artificial atoms” in terms of size, shape, and crystal
    phase as well as core and surface compositions. We present here a bottom-up approach
    to produce Pb–Ag–K–S–Te nanocomposites, which is a highly promising system for
    thermoelectric energy conversion. First, we developed a high-yield and scalable
    colloidal synthesis route to uniform lead sulfide (PbS) nanorods, whose tips are
    made of silver sulfide (Ag2S). We then took advantage of the large surface-to-volume
    ratio to introduce a p-type dopant (K) by replacing native organic ligands with
    K2Te. Upon thermal consolidation, K2Te-surface modified PbS–Ag2S nanorods yield
    p-type doped nanocomposites with PbTe and PbS as major phases and Ag2S and Ag2Te
    as embedded nanoinclusions. Thermoelectric characterization of such consolidated
    nanosolids showed a high thermoelectric figure-of-merit of 1 at 620 K.

  text: The bottom-up assembly of colloidal nanocrystals is a versatile methodology
    to produce composite nanomaterials with precisely tuned electronic properties.
    Beyond the synthetic control over crystal domain size, shape, crystal phase, and
    composition, solution-processed nanocrystals allow exquisite surface engineering.
    This provides additional means to modulate the nanomaterial characteristics and
    particularly its electronic transport properties. For instance, inorganic surface
    ligands can be used to tune the type and concentration of majority carriers or
    to modify the electronic band structure. Herein, we report the thermoelectric
    properties of SnTe nanocomposites obtained from the consolidation of surface-engineered
    SnTe nanocrystals into macroscopic pellets. A CdSe-based ligand is selected to
    (i) converge the light and heavy bands through partial Cd alloying and (ii) generate
    CdSe nanoinclusions as a secondary phase within the SnTe matrix, thereby reducing
    the thermal conductivity. These SnTe-CdSe nanocomposites possess thermoelectric
    figures of merit of up to 1.3 at 850 K, which is, to the best of our knowledge,
    the highest thermoelectric figure of merit reported for solution-processed SnTe.
