A new type of organic electro-optic device combining an organic light emitting diode with an organic photovoltaic cell is studied. The structure is ITO/NPB/Alq3/CuPc/C60/NPB/Alq3/LiF/Al. NPB/Alq3 functions as the light-emitting layer; meanwhile CuPc/C60 functions as a photonic/electric energy transfer cell. The device presents different current density-voltage and power density-voltage curves when in the forward voltage scan then in the backward voltage scan. These transition from a high (ON) to low (OFF) luminance renders a prototype to realize a switchable organic electroluminescence. The conversion efficiency of the optioelectric layer is 0.153%. Several methods to improve the conversion efficiency are also discussed.
