Sb 2 Se 3 Thin-Film Solar Cells Exceeding 10% Power Conversion Efficiency Enabled by Injection Vapor Deposition Technology.

Due to their attractive anisotropic optoelectronic characteristics, Binary Sb 2 Se 3 semiconductors are promising as the absorber materials in inorganic chalcogenide compound photovoltaics are promising. However, Sb 2 Se 3 solar cells suffer from extensive and unusual intrinsic defects due to the poor symmetry of the quasi-crystalline crystal structure, resulting in a significant voltage deficit that reduces the ultimate power conversion efficiency. owing to poor carrier recombination and excellent carrier transportation and extraction, the resulting Sb 2 Se 3 thin-film solar cells have a PCE of 10. 12%, owing to subsidized carrier recombination and excellent carrier transport and extraction.
