This work reports the fabrication process for preparation of perovskite films with good quality morphology and optimal thickness by a simple process of more than one spin coating or multiple spin coating (MSC) method. It should be noted that perovskite films with good quality morphology and optimal thickness are prepared without antisolvent engineering in full air conditions. In this work, we obtained an optimal good power conversion efficiency (PCE) value for CsPbI3 perovskite solar cells (PSCs) at 11.69%. Although, the PCE result is not high enough, however, this MSC method provides a simple and uncomplicated approach for fabrication of PSCs. (PCE) value for at 11.69%. CsPbI3.
