Abstract
Abstract In a photoelectric conversion panel which has a laminate member for photoelectric conversion use which includes a PIN type non-single-crystal laminate member formed on a substrate, the substrate is formed by a thin, flexible, chemically reinforced glass sheet. A plurality of such photoelectric conversion panels are arranged side by side through using a flexible plastic frame reinforced with carbon fibers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
A photoelectric conversion panel comprising: a light-transparent substrate having a potassium containing surface layer; a laminated member formed on the light-transparent substrate and comprising, in sequence, a light-transparent first conductive layer, at least one PIN type non-single-crystal semiconductor laminate photoelectric conversion member, and a second conductive layer; a first impurity blocking layer formed of silicon nitride and provided between the light-transparent substrate and the laminate member for preventing entrance of unnecessary impurities into the laminate member from the light-transparent substrate; and a second impurity blocking layer formed on the laminate member for preventing entrance of unnecessary impurities into the laminate member from the outside.
Claim 2
Dependent Claim
104 words
A photoelectric conversion panel comprising: a light-transparent substrate having a potassium containing surface layer; a laminated member formed on the light-transparent substrate and comprising, in sequence, a light-transparent first conductive layer, at least one PIN type non-single-crystal semiconductor laminate photoelectric conversion member, and a second conductive layer; a first impurity blocking layer formed of silicon nitride and provided between the light-transparent substrate and the laminate member for preventing entrance of unnecessary impurities into the laminate member from the light-transparent substrate; and a second impurity blocking layer formed on the laminate member for preventing entrance of unnecessary impurities into the laminate member from the outside.
