Perovskite solar cells (PSCs) have attracted a lot of attention among the scientific community due rapid progress in photo-conversion efficiency (PCE) from 3% to above 22% and because of their low-cost fabrication with the ability to fabricate on flexible substrate. 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) and lead thiocyanate Pb(SCN)₂ as a dopant in MAPbI₃ increases the solar cell performance. At the same time in ITO resistance of PET substrate has a huge effect on the PCE due to its variation in transmittance. Therefore, in this 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 the effect of using different type of multication perovskite as absorber material. At the same time addition of Pb(SCN)₂ and effect employing different antisolvent, different PET/ITO resistance will be reported.
