CuSCN Modified Back Contacts for High Performance CZTSSe Solar Cells

Advanced Functional Materials, 2023
AbstractOptimization of the back contact interface is crucial for improving the performance of Cu2ZnSnS4 (CZTS) thin film solar cells. In this paper, self‐depleted CuSCN is deployed as an intermediate layer at the Mo/CZTS interface to improve the quality of the back contact.

Analysis of CZTSSe Monograin Layer Solar Cells

, 2011
Monograin layer (MGL) solar cell combines the features of a monocrystalline solar cell and a thin film solar cell. The photoactive layer is formed from the kesterite-stannite semiconductor Cu2SnZn(S,Se)4 (CZTSSe) material with the single-crystalline grains embedded into the epoxy resin (Altosaar et al., 2003).
