Abstract: The invention relates to thin-film solar power modules. The problem associated with known thin-film solar power modules is that the barrier effect of the front film does not prevent moisture from permeating the space between the solar cell and the cover film when exposed to moisture over a longer period of time. In order to solve this problem, the solar module comprises, starting from the solar cell (6), the following layer structure: front: an inorganic barrier layer (2), an inorganic-organic hybrid polymer barrier layer (3), a transparent adhesive layer (4a), a transparent cover film (1b); back: a transparent adhesive layer (4b), a standard backing film (7b).
