Lead thiocyanate in the perovskite precursor can increase the grain size of a perovskite thin film and reduce the conductivity of the grain boundaries, leading to perovskite solar cells with reduced hysteresis and enhanced fill factor. A planar perovskite solar cell with grain boundary and interface passivation achieves a steady-state efficiency of 18.42%.
钙钛矿前驱体中的 lead thiocyanate 可以增加钙钛矿薄膜的晶粒尺寸,并降低晶界的电导率,从而使钙钛矿太阳能电池的滞后现象减小,填充因子增强。具有晶界和界面钝化的平面钙钛矿太阳能电池达到了 18.42%的稳态效率。
