【Abstract】 An organic photovoltaic（PV） cell, ITO/MEH-PPV/Alq₃/LiF/Al, was fabricated. The MEH-PPV and Alq₃ are the electron-acceptor and donor in the cell, respectively. The respond region matchs the adsorption of Alq₃ film. Under UV light with 0.5 mW·cm^-2 , the cell shows a short-circuit current of 2.4 μA·cm^-2 , open-circuit voltage of 2.6 V, a fill factor of 0.71, and a power conversion efficiency of 0.9%。 It was found that the PV cell indicates electroluminescence （EL） performance and could emit orange light at DC voltage. The maximum luminance is about 1 000 cd·cm^-2 at 15 V.更多还原
