Abstract

A simple synthesis of an ionic liquid is carried out using a trialkylphosphine and an alkyl halide. The results showed that the quality of perovskite crystals is enhanced by the incorporation of BPI, when the percentage is 1.5% the PCE of champion PSCs MA(BPI)PbI increases significantly from 15.5%, with a of 0.957 mV, of 23.6 mA cm, and an FF of 68.4%. Stability tests show that excess BPI by 20% has a protective effect against humidity, MA(BPI)PbI was more stable towards humidity, losing only 20% efficiency for 200 h.

摘要

使用三烷基膦和卤代烷进行离子液体的简单合成。结果表明，当BPI的掺入百分比为1.5%时，钙钛矿晶体的质量得到提高，冠军PSC的MA(BPI)PbI的PCE从15.5%显著增加，开路电压为0.957 mV，短路电流密度为23.6 mA/cm²，填充因子为68.4%。稳定性测试表明，过量20%的BPI对湿度有保护作用，MA(BPI)PbI对湿度更稳定，在200小时内效率仅损失20%。
