A study of kapton as a flexible substrate for perovskite solar cells ...
1. Introduction. The remarkable rise of perovskite solar cells (PSC) in recent years has been met with significant enthusiasm, largely due to their impressive power conversion efficiencies and relatively simple manufacturing processes [[1], [2], [3]].Flexible substrates, such as Polyethylene Terephthalate (PET) and Polyethylene Naphthalate …
