Abstract

A flexible photodetector based on the bulk heterojunction of an organometallic halide perovskites CH₃NH₃PbI₃ and an organic dye Rhodamine B (RhB) has been fabricated via a solution casting process. It showed a high responsivity (R_max = 43.6 mA/W) to visible lights, short response time (t_r ≈ 60 ms, t_d ≈ 40 ms), high on-off ratio (I_on/I_off ≈ 287) and satisfactory stability because of its Schottky barrier structure and the dye enhanced light absorption.
