Abstract: Provided is a method of manufacturing a high efficiency flexible thin film solar cell module including a see-thru pattern. The method of manufacturing a flexible thin film solar cell module includes: sequentially forming a light-absorbing layer, a first buffer layer, and a first transparent electrode layer on the release layer; forming a second buffer layer on the exposed bottom surface of the light-absorbing layer; forming a P2 scribing pattern by removing at least one portion of each of the first buffer layer, the light-absorbing layer, and the second buffer layer; forming a second transparent electrode layer on the second buffer layer and the first transparent electrode layer exposed by the P2 scribing pattern; and forming a P4 see-thru pattern by selectively removing at least one portion of the first buffer layer, the light-absorbing layer, the second buffer layer, and the second transparent electrode layer.

Abstract: Provided is a see-through thin film solar cell module including a transparent substrate, a first back electrode deposited on a first surface of the transparent substrate, a second back electrode deposited on the first back electrode and including a MoSe2 layer, an absorber layer deposited on the second back electrode and including selenium (Se) or sulfur (S), and a laser scribing pattern formed by partially removing the absorber layer.
