Abstract
A solar cell includes a metal layer and a chalcopyrite compound semiconductor layer in this order on a polyimide film. A manufacturing method according to the present invention includes the following steps in the order: cast applying a polyimide precursor solution onto a support base containing an alkali metal; imidizing the polyimide precursor by heating to form a stacked body including a polyimide film on the support base; forming a metal layer on the polyimide film of the stacked body; and forming a chalcopyrite compound semiconductor layer on the metal layer.
