Abstract In this work, synthesis and characterization of polyaniline:poly (styrene sulfonate) (PANI:PSS) is prepared with different ratios of the doping PSS for producing an efficient hole extraction layer in inverted planar perovskite solar cells. The PANI to PSS ratios are investigated using ratios of 1:3, 1:4, 1:5, 1:6 and 1:7 to find the optimum ratio for high performance perovskite cells. It is observed that decreasing the PSS content leads to increase the conductivity, which reached the maximum value at 1:4 ratio, then a slight decrease happens for 1:3 ratio. The hole extraction ability also increases with decreasing the PSS concentration. The optimum ratio of PANI:PSS is 1:4, which shows the best performance as HTL, the average short-circuit current density and fill factor are enhanced compared with the cells of the performance of 1:3 and 1:5 ratios. The highest cell performance for the cell with the ratio of 1:4 which has Jsc, Voc, FF and efficiency 22.5 mA/cm2, 0.87 V, 0.42 and 8.22 % respectively.

聚苯胺：聚（苯乙烯磺酸盐）不同比例对钙钛矿太阳能电池空穴提取能力的影响

摘要 在这项工作中，合成和表征了聚苯胺：聚（苯乙烯磺酸盐）（PANI：PSS）和不同比例的 PSS 掺杂比例，用于在倒置平面钙钛矿太阳能电池中制备有效的空穴提取层。使用 1:3、1:4、1:5、1:6 和 1:7 的比率研究 PANI 与 PSS 的比率，以找到高性能钙钛矿电池的最佳比率。观察到降低 PSS 含量导致电导率增加，在 1:4 比例时达到最大值，然后在 1:3 比例时略有下降。空穴提取能力也随着 PSS 浓度的降低而增加。PANI:PSS的最佳比为1:4，表现出作为HTL的最佳性能，平均短路电流密度和填充因子比1:3和1:1性能的电池有所提高：5 个比率。Jsc、Voc、FF 和效率分别为 22.5 mA/cm2、0.87 V、0.42 和 8.22 % 的电池比为 1:4 的电池性能最高。
