Organic-inorganic hybrid lead halide perovskite solar cells (PSCs) have seen a huge surge in photovoltaic performance in recent years. There are still some hurdles such as its chemical instability, degradation in ambient, which are the critical bottlenecks from commercial perspectives. Two-dimensional (2D) perovskites have emerged as the possible solution to these hurdles. They have provided the PSCs with more stability but attaining high PCE with 2D perovskites is still a problem. This is due to the insulating nature of the hydrophobic spacer head groups which lie in-between the conducting inorganic slabs. We have fabricated PSCs with Ruddlesden Popper (RP) 2D perovskite as the photoabsorber using CH3(CH2)3NH3)2(CH3NH3)n-1PbnI3n+1 layers at multiple stoichiometric compositions to study the stability and impact on PCE for these various formulations. These results will shed insights toward the integration of solution-processed 2D perovskite films for solar cells to enhance stability and performance of the devices.
