Hydrazine Hydrate-Induced Surface Modification of CdS Electron Transport Layer Enables 10.30%-Efficient Sb₂(S,Se)₃ Planar Solar Cells.

ABSTRACT: Antimony selenosulfide (Sb₂(S,Se)₃), a simple alloyed compound containing earth-abundant constituents, with a tunable bandgap and high absorption coefficient has attracted significant attention in high-efficiency photovoltaic applications. Optimizing interfacial defects and absorber layers to a high standard is essential in improving the efficiency of Sb₂(S,Se)₃ solar cells. In particular, the electron transport layer (ETL) greatly affects the final device performance of the superstrate structure. In this study, a simple and effective hydrazine hydrate (N₂H₄) solution post-treatment is proposed to modify CdS ETL in order to enhance Sb₂(S,Se)₃ solar cell efficiency. By this process, oxides and residual c
