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.

Impact of Sb and Na Doping on the Surface Electronic Landscape of Cu2ZnSnS4 Thin Films [PDF]
, 2018 Open-circuit voltage deficiency is the key limiting factor in Cu2ZnSnS4 (CZTS) thin-film solar cells, which is commonly associated with band tails and deep gap states arising from elemental disorder.

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.

Influence of reaction conditions on the properties of solution-processed Cu2ZnSnS4 nanocrystals [PDF]
, 2014 Cu2ZnSnS4 nanocrystals were fabricated by hot injection of sulphur into a solution of metallic precursors. By careful control of the reaction conditions it was possible to control the elemental composition of the nanocrystals such that they are suitable ...

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.
