<p><P>PROBLEM TO BE SOLVED: To provide a photoelectric transducer of high reliability at low cost. <P>SOLUTION: In this photoelectric transducer, a large number of granular crystal semiconductors exhibiting a conductivity type are arranged on a substrate having one electrode layer and bonded to the substrate. Parts between the semiconductors are filled with insulator, a semiconductor layer exhibiting an opposite conductivity type is arranged on the semiconductors, and the other electrode is connected with the semiconductor layer exhibiting the opposite conductivity type. The granular crystal semiconductors are composed of silicon. The insulator is formed of paste of glass composition powder for low temperature backing. Ratio of particles whose diameter is at most 1μm is at least 5% of the whole grain diameter distribution, and ratio of particles whose diameter is at least 5μm is at least 20% of the whole grain diameter distribution. The insulator is glass composition whose coefficient of thermal expansion at 40-400°C is 40-80×10<SP>-7</SP>/°C. As a result, the insulator with which the parts between the granular crystal semiconductors are filled and which prevents generation of defects such as cracks, foaming and abnormal deposit and have stable reliability can be formed, and the photoelectric transducer of high reliability can be provided. <P>COPYRIGHT: (C)2003,JPO</p> |
