Perovskite solar cell devices on flexible stainless-steel substrate

This work demonstrates the perovskite (CH ₃ NH ₃ PbI ₃ ) solar cell devices on flexible stainless-steel as a substrate that can be used for flexible electronics applications. The preliminary attempts of the device fabrication showed a power conversion efficiency of 3.45%. The reasons for obtaining device performance and scope of their improvement are investigated and discussed.
