  text: Copper-based chalcogenides that comprise abundant, low-cost, and environmental
    friendly elements are excellent materials for a number of energy conversion applications,
    including photovoltaics, photocatalysis, and thermoelectrics (TE). In such applications,
    the use of solution-processed nanocrystals (NCs) to produce thin films or bulk
    nanomaterials has associated several potential advantages, such as high material
    yield and throughput, and composition control with unmatched spatial resolution
    and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts
    of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic
    resonance and infrared spectroscopy, these NCs were used to produce dense CASe
    bulk nanomaterials for solid state TE energy conversion. By adjusting the amount
    of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673
    K were reached. Such high ZT values are related to an optimized carrier concentration
    by Sn doping, a minimized lattice thermal conductivity due to efficient phonon
    scattering at point defects and grain boundaries, and to an increase of the Seebeck
    coefficient obtained by a modification of the electronic band structure with Bi
    doping. Nanomaterials were further employed to fabricate ring-shaped TE generators
    to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when
    exposed to a 160 °C temperature gradient. The simple design and good thermal contact
    associated with the ring geometry and the potential low cost of the material solution
    processing may allow the fabrication of TE generators with short payback times.
