摘要
钙钛矿太阳能电池(PSC)稳定性不好,遇水容易导致有毒铅离子的释放,因此未能实现工业化。本研究采用湿沉淀法合成了两种纳米级的HAPs用于去除PSCs中降解出的Pb(Ⅱ)。采用Langmuir模型建立吸附等温线,HAP的最大吸附量可达1322.2mg/g(pH=5)。此外,将HAP用于制备新型PSC,与传统PSC相比,故障模拟过程中Pb(Ⅱ)释放量更少。
Perovskite solar cells(PSCs)are easy to release toxic lead ions(Pb(Ⅱ))when water infiltrat,so they have not been industrialized.Therefore,in this project,two nanoscale HAPs were synthesized by wet precipitation method to remove degraded Pb(Ⅱ)from PSCs.Langmuir model was used to establish adsorption isotherms,and the maximum HAP adsorption capacity was 1322.2mg/g(pH=5).In addition,PSCs with HAP released less Pb(Ⅱ)during failure simulation compared to traditional PSCs.
