The electrical and optical properties of kesterites
Journal of Physics: Energy, 2019 AbstractKesterite Cu2ZnSn(SxSe1-x)4(CZTSSe) semiconductor materials have been extensively studied over the past decade, however despite significant efforts, the open circuit voltage remains below 60% of the theoretical maximum. Understanding the optical and electrical properties is critical to explaining and solving the voltage deficit.

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.

Characterization and modelling of Sn-Ge bandgap-graded kesterite thin-film solar cells
, 2023 The performance of kesterite-based photovoltaic devices is famously limited by significant open-circuit voltage (Voc) deficits that restrain their efficiency to levels lower than competing inorganic thin-film technologies such as Cu(In,Ga)Se2 (CIGS) and ...

Thermal and electrical conductivity of single crystalline kesterite Cu2ZnSnS4
Materials Research Express, 2020 For single crystalline sulfur-based kesterite Cu _2 ZnSnS _4 the electrical and thermal conductivity are measured from 20 K to 320 K. The electrical conductivity decreases exponentially with decreasing temperature.

Existence of off stoichiometric single phase kesterite
, 2016 In this work the flexibility of the kesterite structure is discussed. It is shown that kesterite type CZTS and CZTSe can deviate from stoichiometric composition by the formation of intrinsic point defects leading to different off stoichiometric kesterite

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.
