Abstract (AI)
Halide perovskites solar cells have the potential to exhibit higher energy conversion efficiencies with ultrathin films than conventional thin-film solar cells based on CdTe, CuInSe2 , and Cu2 ZnSnSe4 . The superior solar-cell performance of halide perovskites may originate from its high optical absorption, comparable electron and hole effective mass, and electrically clean defect properties, including point defects and grain boundaries.
Key Findings
1
Comparable electron and hole effective masses may contribute to efficient carrier transport and enhanced perovskite photovoltaic performance.
2
Electrically benign defect properties, including those of point defects and grain boundaries, may help explain the strong performance of halide perovskite solar cells.
3
Halide perovskite solar cells could achieve higher energy-conversion efficiencies with ultrathin films than conventional CdTe, CuInSe2, and Cu2ZnSnSe4 thin-film cells.
4
High optical absorption is identified as a possible origin of halide perovskites’ superior solar-cell performance.
