A high performance heterojunction organic ultraviolet photodetector based on NPB and Bphen has been fabricated. A transparent conducting polymer PEDOT:PSS coated quartz substrate instead of ITO coated glass substrate as anode is propitious to detect shorter wavelength ultraviolet light. As a result, the device shows a low dark current density, a high responsivity of 502 mA/W and a detectivity of 2...
