Effect of Na2S soaking on the properties of Cu2ZnSn(S,Se)4 films and solar cells

Materials Letters, 2020
Abstract In this paper, we propose a Na2S soaking process (used as post-treatment process for the precursor films) for the non-vacuum prepared Cu2ZnSn(S,Se)4 (CZTSSe) films. The CZTSSe film prepared without this process show triple-layer structure in which fine-grain layer and obvious layer-boundaries exist.

Analysis of photovoltaic properties of Cu2ZnSn(S,Se)4-based solar cells

Solar Energy Materials and Solar Cells, 2014
Abstract Analyses of current–voltage characteristics of Cu2ZnSn(S,Se)4-based solar cells reveal a non-superposition between dark and illuminated curves. Numerical simulations have been carried out to model the behavior of the Cu2ZnSn(S,Se)4/CdS heterojunction, and to extract from experimental data the minority carrier diffusion length in the absorber.

Band alignment of Cd-free (Zn, Mg)O layer with Cu2ZnSn(S,Se)4 and its effect on the photovoltaic properties

Optical materials (Amsterdam), 2018
Cu2ZnSn(S,Se)4 (CZTSSe) is an interesting absorber material for thin film solar cells. However, one of the key challenges for the kesterite-based solar cells is to improve the open-circuit voltage (Voc) deficit, which is resultant of recombination at the

Defect-Level Trap optimization in Cu2ZnSn(S,Se)4 Photovoltaic Materials via Sb3+-Doping for over 13% Efficient Solar Cell

Journal of Materials Chemistry A
In this study, Sb2S3 was introduced into the two-step selenization process to promote bottom grain growth and reduce the surface roughness of the Cu2ZnSn(S,Se)4 light-absorber layer.

Cu2ZnSn(S,Se)4 photovoltaic absorber fabrication by hydride chalcogenization of electrodeposited precursors

2015
"Cu2ZnSn(S,Se)4 (CZTSSe) is a semiconducting material with potential application as the absorber layer in thin-film photovoltaic (PV) devices. Closely related to the commercially available Cu(In,Ga)Se2 (CIGS) absorber material, CZTSSe consists of more readily-available materials, and may therefore offer cost reduction and highly scalable production ...
