| Abstract: | Polymer/inorganic hybrid ultra violet (UV) photovoltaic device is fabricated by using poly(N-vinyl-carbazole) (PVK) and zinc sulfide (ZnS). The device shows promising photovoltaic characteristics with a high open-circuit voltage of 1.65 V, and a short-circuit current of 46.8 μA/cm2 under the illumination of 340 nm UV light with the intensity of 14 mW/cm2. Besides, much correlative photocurrent spectra of the device under forward and reverse applied bias manifest the transport mechanism of charge carriers in PVK/ZnS bilayer systems. |
