Using vacuum evaporation and sputtering process, we prepared a photoelectric transistor with the vertical structure of Cu/copper phthalocyanine (CuPc)/Al/copper phthalocyanine (CuPc)/ITO. The material of CuPc semiconductor has good photosensitive properties. Excitons will be generated after the optical signal irradiation in semiconductor material, and then transformed into photocurrent under the built-in electric field formed by the Schottky contact, as the organic transistor drive current makes the output current enlarged. The results show that the I–V characteristics of transistor are unsaturated. When device was irradiated by full band (white) light, its working current significantly increased. In full band white light, when V_ec = 3 V, the ratio of light and no light current was ranged for 2.9–6.4 times. Device in the absence of light current amplification coefficient is 16.5, and white light amplification coefficient is 98.65.
