Conductivity mechanisms and influence of the Cu/Zn disorder on electronic properties of the powder Cu2ZnSn(S1-xSex)4 solid solutions

Journal of Materials Research and Technology, 2021
One of the major reasons for a recent stuck of the development of kesterite based photovoltaic devices is related to the problems in their open circuit voltage. Several limitations can be pointed out as a possible origin.

Band-gap engineering of Cu2ZnSn1-xGe xS4 single crystals and influence of the surface properties [PDF]

, 2016
Thin film solar cells based on Cu2ZnSn(S,Se)4 are very promising, because they contain earth-abundant elements and show high absorptivity. However, the performance of these solar cells needs to be improved in order to reach efficiencies as high as that ...

DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

Nano Select, Volume 7, Issue 3, March 2026.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 271-285, March 2026.
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...
