摘要	Planar CH3NH3PbI3 perovskite based photodetectors are fabricated by a facile and low-cost one-step method. The devices show broad spectral photoresponse from the ultraviolet to whole visible region and the performance can be significantly improved by the introduction of a bipolar transporting MoO3 interface layer between CH3NH3PbI3 film and Au electrode. The photocurrent of the device with an optimized MoO3 layer is about twice that of the reference device without MoO3 layer, which results in a high ON/OFF current ratio of 5.9 x 10(3) at 5 V. Besides, slightly increased photoresponse speed is also found in the optimized device with rise time and decay time of 21.6 and 9.9 ms, respectively. The improvement can be attributed to the improved hole and electron collection efficiency and the quickly filled in or emptied trap states at the CH3NH3PbI3/Au interface due to the introduction of the bipolar transporting MoO3 layer.
