近年来,甲脒基钙钛矿太阳能电池的光电转换效率取得了显著进展,其商业化前景日益明朗.随着钙钛矿电池商业化的快速发展,对于环境友好、成本低廉的钙钛矿前驱体的需求不断增长.甲脒铅碘钙钛矿材料遇水易分解,因此传统钙钛矿粉末合成方法依赖于有机溶剂和惰性气氛手套箱,不具备成本优势.在此背景下,本文提出了一种经济高效的水系合成高纯度δ相甲脒铅碘(δ-FAPbI_(3))粉末的策略.在水溶液中加入过量氢碘酸,碘离子可使不溶性PbI_(2)转化为可溶性[PbI_(2)+n]n-络合物,将FAPbI_(3)的遇水分解转化为溶解,从而使水系合成成为可能.水系合成的甲脒铅碘粉末具有高纯度、低成本优势,可作为钙钛矿薄膜前驱体材料.与以PbI_(2)和FAI的混合物作为前驱体制备的钙钛矿薄膜相比,以水系合成的δ-FAPbI_(3)粉末为前驱体制备的钙钛矿薄膜具有良好的结晶性,降低了缺陷密度,并有效抑制了有害的离子输运和降解过程,从而增强了载流子传输性能和电池稳定性.在环境空气中以合成粉末为前驱体制备的钙钛矿太阳能电池,最高转化效率可达23.24%.
