Inverted perovskite solar cells incorporating RF sputtered NiO thin films as a hole transport layer and window are demonstrated. The electrical optical properties of the engineered using varied sputtering conditions. localized states within bandgap owing to its crystal disorder nonstoichiometric features affect transmittance which in turn influences J
