Abstract: Disclosed are a flexible electrode substrate including a porous electrode, a method for manufacturing the flexible electrode substrate, and an energy storage element including the flexible electrode substrate. The flexible electrode substrate can be attached to various objects due to the excellent electrochemical properties and the adhesive properties thereof and thus is very useful. In particular, since the flexible electrode substrate can be used as an electrode of an energy storage element, an energy storage element including the flexible electrode substrate can be attached to various objects and thus can be used as a sticker-type energy storage element. In addition, the flexible electrode substrate can be easily manufactured by transfer method using a difference in adhesive strength and thus allows a simple manufacturing process thereof. Furthermore, electrodes having various patterns can be manufactured with high level of efficiency through simple adjustment of the manufacturing process.

Abstract: Disclosed is a method of forming a chalcopyrite light-absorbing layer for a solar cell, including: forming a thin film including a chalcopyrite compound precursor; and radiating light on the thin film, wherein the chalcopyrite compound precursor absorbs light energy and is thus crystallized. When forming the chalcopyrite light-absorbing layer, light, but not heat, is applied, thus preventing problems, including damage to a substrate due to heat and formation of MoSe2 due to heating of the Mo rear electrode. Furthermore, long-wavelength light, which deeply penetrates the thin film, is first radiated, and short-wavelength light, which shallowly penetrates the thin film, is subsequently radiated, thereby sequentially forming the chalcopyrite light-absorbing layer from the bottom of the thin film.
