Tóm tắt

Antimony-based halide perovskites have attracted significant attention owing to their unique optoelectronic properties and low toxicity. However, the distinct defect physics and high exciton binding energy of antimony-based perovskites compared with their lead-based analogues significantly hinder the photovoltaic performance of antimony-based perovskite solar cells (PSCs). In this work, a feasible strategy by regulating the precursor composition is introduced to mitigate the defects and impurity phases of Cs
