| Popis: | Organic ultraviolet (UV) light-sensitive photovoltaic (PV) diodes, based on 4, 4′, 4″-tris-(2-methylphenyl phenylamino) triphenylamine (m-MTDATA) as an electron donor and copper phthalocyanine (CuPc) as acceptor, have been fabricated. The PV diode exhibits high open-circuit voltage ( V OC ) of 1.05 V under illumination of 365 nm UV light with 1.7 mW/cm 2 , although the CuPc was generally used as electron donor in other PV diodes. And the short-circuit current ( I SC ) of 54.6 μA/cm 2 , fill factor (FF) of 0.304 and power conversion efficiency ( η e ) of 1.03% are respectively achieved. This diode can accurately detect the UV radiation according to photo-generated voltage signal. |
