Abstract

PURPOSE:To improve quantum efficiency by forming P type or N type material layers on both sides of an N type or a P type crystal to form two diodes which are connected in series in reverse direction. CONSTITUTION:On a metal electrode 2, a P type material 3 of amorphous form, etc., is sticked all over, an N type material 4 which can form a hetero junction with the material 3 is grown on it, a material 5 the same as the material 3 is formed on the material 4, and a metallic material 6 is formed on the material 5. By so doing, two P-N junction diodes connected in reverse direction are obtained. Next, a transparent electrode 7 is attached to the incidence side of the N type material and a metal electrode 8 is attached to the opposite face of the material. If positive potential is given to the electrode 7, negative potential is given to electrodes 2, 6 and 8, and photons enter into the electrode 7 and the junction faces 9 and 10, positive holes are formed, are drawn by the field and flow to the electrodes 2 and 6 as a photoelectric current. It mans that the photoelectric current is doubled, and since the light enters in a direction parallel to the junction faces 9 and 10, quantum efficiency is improved. These N type material and P type material may be changed with each other.
