Solution processable perovskite solar cells (PSCs) have attracted a lot of attention in recent years, which have already reached beyond the photo conversion efficiency (PCE) of 20%, employing a multication approach. However, PCE on flexible PSCs is still behind from the reported values on rigid substrates. It has been already investigated that a small addition of formamidinium (FA) in methylammonium lead iodide (MAPbI₃) increases the solar cell performance. Therefore, in the present work, we aimed to optimize the performance of flexible PSCs on Indium tin oxide (ITO) coated polyethylene terephthalate (PET) film by utilizing the similar approach. The present work also discusses about effect of using different type of hole transporting material. Moreover, doping effect of lead (II) thiocyanate Pb(SCN)₂ on flexible PSCs will be reported.
