title: Organic Dye-Sensitized CH3NH3PbI3Hybrid Flexible Photodetector with Bulk Heterojunction Architectures.
abstract: A flexible photodetector based on the bulk heterojunction of an organometallic halide perovskites CH3NH3PbI3and an organic dye Rhodamine B (RhB) has been fabricated via a solution casting process. It showed a high responsivity (Rmax= 43.6 mA/W) to visible lights, short response time (tr≈ 60 ms, td≈ 40 ms), high on-off ratio (Ion/Ioff≈ 287) and satisfactory stability because of its Schottky barrier structure and the dye enhanced light absorption.
