This research aims to control the orientation of lead halide perovskite (composition formula: CH₃NH₃PbI₃, MAPbI₃) which has attracted much attention in recent years as photoactive layer for solar cells. We focused on the heteroepitaxial growth on rubrene and fabricated MAPbI₃ film on rubrene/pentacene. Grazing incidence wide angle X-ray scattering (GIWAXS) measurement revealed that rubrene/pentacene can control out-of-plane orientation of MAPbI₃.
