In this work, we designed flexible organic-inorganic hybrid photodetectors on various flexible substrates, including polyethylene terephthalate （PET）, common Sellotape and polydimethylsiloxane （PDMS）, with n-type phenyl-C61-butyric acid methyl ester （PCBM） and p-type pearl-like GaP nanowires （NWs） as the active materials. The as-fabricated hybrid devices exhibited an optimized performance superior to the device made of pristine GaP NWs, with a fast response time （43 ms） and high on/off ratio （-170）. Under different bending conditions, the flexible hybrid photodetectors demonstrated excellent flexibility and electrical stability, which make them very promising for further large-scale, high sensitivity and high speed photodetector applications.展开更多
