Numerical analysis guidelines for the design of efficient novel nip structures for perovskite solar cell
Abstract In this work, detailed analysis and guidelines were provided using solar cell capacitance software (SCAPS) to characterize possible novel n i p structures for M A P b I 3 based perovskite solar cells having device power conversion efficiency (PCE) greater than 22% To accomplish this task, we first optimize the performance of T i O 2 M A P b I 3 S p i r o M e O T A D device structure by finding the optimal parameters of thickness and doping concentration for each layer. After device optimization, we first apply eight different electron transport layers (ETL) to the given device structure by replacing each with T i O 2 in the SCAPS environment and analyzing the effect of each ETL on device performance. After evaluating device structure with different ETL layers, we then apply six different kesterite and quaternary compounds as a possible candidate for the HTL layer. From an analysis, we found forty nine new possible n i p device structures for each ETL and HTL layer having PCE variation from a value of 2% to 26.69% Among them the best possible n i p structures, we achieved are E T L M A P b I 3 C N T S having PCE greater than 24.84% to the maximum value of 26.69%
