Abstract
Organic-inorganic hybrid perovskite (OIHP) based photo-responsive devices include an OIHP active layer disposed between a cathode layer and an anode layer, and an electron extraction layer disposed between the cathode layer and the active layer. The electron extraction layer includes a layer of C60 directly disposed on the active layer. The active layer includes an organometal trihalide perovskite layer (e.g., CH3NH3PbI2X, where X includes at least one of Cl, Br, or I).
