The utility model relates to a device with organic electroluminescence and photovoltaic functions. The utility model belongs to the technical field of electroluminescence. The utility model has the structure of ITO / M-MTDATA / M-MTDATA: Alq#-< 3 > / Alq#-< 3 > / MgAg, wherein the ITO is a positive electrode; the M-MTDATA is an organic layer; the M-MTDATA: Alq#-< 3 > is an organic mixed layer; the Alq#-< 3 > is a quinoline aluminum layer; the MgAg is a negative electrode. Since the organic mixed layer M-MTDATA: Alq#-< 3 > and the Alq#-< 3 > are continuous layers, the utility model can also be expressed as ITO / M-MTDATA / Alq#-< 3 > / Mg: Ag. Obvious interface does not exist between the ITO and the Mg: Ag but rather a blurry interface. The utility model driven by direct current voltage can emit yellowish green light of peak value 600NM and can measure open-circuit voltage about 1.3-2V and short-circuit current of 9.8-20 mu A/CM# < 2 >, the corresponding quantum efficiency is 3.8 percent, and maximum energy conversion efficiency is 0.40 percent.
