Effect of Hole transport layer PTAA and PEDOT:PSS on the Morphology and Efficiency of Inverted Planer Perovskiet Cell Solar

In this study, the structure of the inverted planer solar cell was used because of its prominent features, such as low temperature construction and low cost construction, the effect of two layers of PDOT:PSS and PTAA as the underlying perovskite on the morphology perovskite layer and parameters affecting solar cell performance Jsc, Voc, FF, PCE were investigated.
SEM and AFM images showed that Proper morphology and high coverage of perovskite film with PTAA compared to perovskite film with PEDOT: PSS resulted in increased light absorption and efficiency in perovskite solar cell with PTAA. Their yields reached 11.37, while the maximum PDOT: PSS-based solar cell efficiency was 9.23.
