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.
