Dynamic Impurity Redistributions in Kesterite Absorbers [PDF]
physica status solidi (b), 2020 Cu2ZnSn(S,Se)4 is a promising nontoxic earth‐abundant solar cell absorber. To optimize the thin films for solar cell device performance, postdeposition treatments at temperatures below the crystallization temperature are normally performed, which alter the surface and bulk properties.

High-pressure behavior of disordered kesterite-type Cu2ZnSnS4 [PDF]
Applied Physics A, 2021 AbstractWe have investigated the high-pressure structural and vibrational behavior of the disordered kesterite-type Cu2ZnSnS4 compound at ambient temperature. Our experimental and theoretical investigations have revealed a clear structural transition to a GeSb-type phase close to 15 GPa, a tetragonally distorted variant of the NaCl-type phase.

Photovoltaic response of natural Kesterite crystals [PDF]
Solar Energy Materials and Solar Cells, 2016 Abstract The photoelectrochemical performance of naturally occurring single and multicrystalline Kesterite or Cu2(Zn,Fe)SnS4 (CZTS) is presented. Elemental analyses of the crystals indicate high sulfur to metal atomic ratios and the presence of 12.3–14.5 at% of iron presumably in the 2+ metal site replacing zinc in the lattice.

Doping and alloying of kesterites
Journal of Physics: Energy, 2019 Abstract Attempts to improve the efficiency of kesterite solar cells by changing the intrinsic stoichiometry have not helped to boost the device efficiency beyond the current record of 12.6%. In this light, the addition of extrinsic elements to the Cu2ZnSn(S,Se)4 matrix in various quantities has emerged as a popular topic aiming to ...

High Recovery of Selenium from Kesterite‐Based Photovoltaic Cells [PDF]
European Journal of Inorganic Chemistry, 2020 The use of photovoltaic cells is constantly increasing and, in particular, a new generation of thin‐film photovoltaic (PV) cells is under development. The absorber of these new cells, kesterite (CZT(S)Se), is composed of abundant chemical elements. Nonetheless, the development of the recycling process for these elements is indispensable for circular ...
