不同官能团对钙钛矿太阳电池的钝化效果(英文)
发布时间:2021-07-01 13:10
为了提高钙钛矿太阳能电池的效率和稳定性,许多具有不同官能团的有机分子已被报道用来钝化钙钛矿表面.然而,不同官能团与其钝化效果的内在关联性却很少被人们了解.本文系统研究和比较了12种不同官能团对钙钛矿太阳电池的钝化作用,结果表明,钝化效果和电池的开路电压随着钝化分子与钙钛矿表面缺陷化学键合强度的增加而具有增加趋势.并且其中四叔丁基苯甲酸可以通过分子间的额外氢键作用,形成具有不溶于水和高熔点的晶体界面层,可以进一步稳定钙钛矿薄膜表面的钝化效果.得益于与钙钛矿的强配位作用和自身的氢键作用,基于四叔丁基苯甲酸钝化的钙钛矿电池获得了21.46%效率.更重要的是,这些器件在45%相对湿度下储存了1年以上(10,080小时),仍能保持88%的初始性能.该工作对于理解钙钛矿表界面的钝化以及进一步提高钙钛矿太阳电池性能和稳定性具有积极借鉴意义.
