To prepare highly efficient optical sensors for UVA light, an organic photovoltaic （PV） device, in which 4,4＇ ,4″-tris [ 3-methylphenyl （ phenyl ） amino ] triphenylamine （ m-MTDATA ） and Re （ CO ） 3 Cl-dipyrido [ 3,2-a ：2＇ ,3＇-c] phenazine（Re-DPPz） are used as an electron donor and an acceptor, respectively, has been fabricated by a vacuum deposition method. Under illumination with UV light （ 365 nm, 1.6 mW/cm^2 ） , the short circuit current, open circuit vohage, fill factor and power conversion efficiency of the PV device are measured to be 57. 1 μA/cm^2, 0. 86 V, 0. 39, 1.2% respectively. These results indicate that the Re-DPPz complex, a promising triplet emitter, is characterized not only by its electroluminescence but also by good PV performance. These experiments also show that utilizing phosphorescent materials is a promising way to improve the PV performance of a device.
