Organometallic halide perovskites have attracted great research interest as light-active materials for use in optoelectronics. Here, we report a high-performance photoconductor based on a methylammonium lead iodide (MAPbI3) film that was prepared from a methylamine-treated MAPbI3/PbI2 perovskite film. An ultrahigh responsivity of 3.6 A/W and detectivity of 5.4×1012 Jones were obtained for the film under 0.5 mW/cm2 white-light illumination. In addition, under 420 nm light irradiation, the film exhibited its highest responsivity and detectivity of 30 A/W and 2.4×1014 Jones, respectively. The excellent photo-response performance results from the improved electronic quality and suppressed nonradiative recombination channels of the treated perovskite thin film.
