英文摘要	Organic-inorganic perovskites are promising light absorbing active materials for photodetectors; however, the performance of current organic-inorganic perovskite-based photodetectors are limited by the high dark current due to hole injection at the cathode interlayer typically composed of fullerene derivatives. We have developed a mixture interlayer by simply blending polymethyl methacrylate ( PMMA) with [6,6]-phenyl-C61-butyric acidmethyl ester (PCBM). Scanning Kelvin probe microscopy imaging reveals that the presence of PMMA reduced the work function of the PCBM: PMMA interlayer, which leads to increased energy barrier for hole injection and better hole-blocking property. Optimized perovskite photodetector with PCBM: PMMA hole-blocking interlayer exhibits a high detectivity of 1.1 x 10(13) Jones, a broad linear dynamic range of 112 dB, and a fast response time of 2.2 mu s.
