Abstract
A thin film solar cell module of see-through type and a method of fabricating the same are provided. First, bi-directional openings are formed in the transparent electrode material layer to avoid problems that affect the production yield such as short-circuit resulted by the high-temperature laser scribing process. Moreover, the thin film solar cell module of see-through type has openings that expose the transparent substrate without covering the transparent electrode material layer to increase the transmittance of the cells.
