Mixture of anti-solvents plays a decisive factor on the preparation of active layers for perovskite photovoltaic applications. This work explores the perovskite precursor treatment with various mixture of anti-solvents, in which it, not only improves in the surface morphology, but also enhances the crystallinity of the CH₃NH₃PbI₃active layer. The toluene mixed with dichlorobenzene in a volume ratio of 1:1 has the best power conversion efficiency of 18.01%. It is also observed that adding certain amount of [6,6]-phenyl-C61-butyric acid methyl ester into the anti-solvent mixture can significantly improve the PCE of PSC by 6%, enhancing the passivation of grain boundary. Moreover, such procedure uses in p-i-n plane perovskite solar cell preparation is applicable to n-i-p stacking mesoporous perovskite solar cell. These perovskite active layer, prepare via this approach, are highly crystalline as well as homogeneous in nature with appropriate grain boundaries.

抗溶剂的混合物在钙钛矿光伏应用的活性层的制备中起决定性的作用。这项工作探索了用各种反溶剂混合物处理钙钛矿前体的方法，该方法不仅可以改善表面形态，还可以提高CH ₃ NH ₃ PbI ₃的结晶度。活动层。甲苯与二氯苯以1：1的体积比混合时，具有18.01％的最佳功率转换效率。还观察到向反溶剂混合物中添加一定量的[6,6]-苯基-C61-丁酸甲酯可以显着提高PSC的PCE 6％，从而增强晶界的钝化。而且，这种在销平面钙钛矿太阳能电池制备中使用的程序适用于夹压堆叠中孔钙钛矿太阳能电池。通过这种方法制备的这些钙钛矿活性层是高度结晶的，并且本质上是均匀的，具有适当的晶界。
