Abstract :
Organic photo-detectors (OPDs) have been discussed as high-speed photo-detectors, which consist of heterostructure of copper phthalocyanine (CuPc) and N,N´-bis(2,5-di-tert-butylphenyl)-3,4,9,10-perylenedicarboximide (BPPC) layers. We analyzed the carrier transport in photodetectors, and the device has a cut-off frequency of more than 70 MHz. The imaging signals were successfully received using the OPD
