摘要：

As the most promising lead-free perovskite, tin-based perovskite has attracted much attention due to its suitable bandgap and low toxicity. However, many defects (tin vacancy defects caused by Sn2+ oxidation to Sn4+, grain boundary defects and point defects) in tin-based perovskite lead to serious losses in device efficiency. Here, a universal and effective doping strategy is delivered to improve the structure and optoelectronic properties of tin-based perovskite films through 2,8-dibromo-dibenzothiophene-S,S-dioxide (BrDS) doping. The introduction of BrDS can effectively inhibit the oxidation...
