PHOTOELECTRIC CONVERSION APPARATUS AND ITS FABRICATING METHOD

摘要

PROBLEM TO BE SOLVED: To overcome the problem of a photoelectric conversion apparatus employing crystalline semiconductor particles that the characteristics are low and the cost is high. SOLUTION: The photoelectric conversion apparatus comprises multiple granular crystalline semiconductors 2 arranged on a substrate 1 having one electrode layer 1, and an insulator 3 filling the gaps of the granular crystalline semiconductors 2 wherein the granular crystalline semiconductors 2 and the substrate 1 are bonded through a complex 20 produced by diffusing particles 22 composed of the material of the granular crystalline semiconductor 2 into an alloy 21 of the granular crystalline semiconductor 2 and the substrate 1. The substrate 1 is composed of aluminum and the granular crystalline semiconductor 2 is composed of silicon and the granular crystalline semiconductor 2 can be bonded well to the substrate 1 by heating them at 577 deg.C or above while touching each other thereby bonding them through the complex 20 produced by diffusing particles 22 composed of the material of the granular crystalline semiconductor 2 into the alloy 21 of the granular crystalline semiconductor 2 and the substrate 1.
