Title:
SOLAR BATTERY AND PROCESS FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/1998/050962
Kind Code:
A1
Abstract:
A solar battery having a semiconductor layer of a chalcopyrite structure as a light absorption layer and a flexible film as a substrate and being prevented from causing breakdown and peel-off of the semiconductor layer of the chalcopyrite structure due to warping of the flexible film during heat treatment. To realize this, a poly(p-phenyleneterephthalamide) film having a coefficient of thermal expansion of 5.0 x 10?-6�/�C is used as a substrate (1). After a Ti-base reinforcing layer (6) is provided on the whole back surface of this substrate (1), a first electrode layer (2) is provided on the front surface of this substrate (1), and a p-type semiconductor layer (3) of a chalcopyrite structure is formed as a light absorption layer on the surface of the layer (2).
