Abstract

A CIS solar cell having flexibility and high conversion efficiency may be produced, using, as a substrate, a polyimide film which is prepared from an aromatic tetracarboxylic acid component comprising 3,3',4,4′-biphenyltetracarboxylic dianhydride as the main component and an aromatic diamine component comprising p-phenylenediamine as the main component, and has a maximum dimensional change in the temperature-increasing step of from 25° C. to 500° C. within a range of from +0.6% to +0.9%, excluding +0.6%, based on the dimension at 25° C. before heat treatment.
