Abstract

PURPOSE:To generate recombination electric fields and to increase an SN ratio by providing a p-i-n junction or an n-i-p junction in a semiconductor having a photoelectric effect to form an internal electric field and further forming energy band into w-n-w structure as well. CONSTITUTION:A semiconductor 1 has the 1st layer 31 by a p type semiconductor or semiinsulator in contact with a conductor 2, the 2nd intrinsic layer 32 and the 3rd layer 33 of an n type, and is constituted with transition regions 37, 36 between the respective layers. Further, the conduction band 38, and valence band 39 of these layers continuous and have no discontinuity such as kinks, dips and the like in terms of energy band. Since such internal electric fields are created, the Hall diffusion to the rear conductor 1 is 10<2>-10<4> times faster than in the prior art, whereby the semiconductor 2 can be reduced to 1/2-1/3 thickness of the prior art and the generation of cracks is reduced as well. The possibility of pollution is eliminated by the use of not semiconductors of CdS but non-crystalline silicon semiconductors, or semiconductors or semiinsulators added with silicone and carbon, nitrogen or oxygen.
