Abstract
A thin-film solar module with an array of photovoltaic cells is provided on a soda-lime transparent substrate of a first area. The substrate supports the array on a second area; the first area extends beyond the second area by a stripped peripheral zone. This arrangement results in reduced corrosion of the substrate and the cathode. In addition, the life of the module is further extended if the module is protected against atmospheric humidity with a cover that leaves an air cavity about the array. In a variant of this arrangement, an isolated strip of the same material as the cathode is provided within the stripped peripheral zone, around the perimeter of the second area.
