A process for the production of thin film solar cell modules having a predetermined transparency

The invention relates to an apparatus and a method for manufacturing thin film solar cell modules having a predetermined transparency may be incorporated in which in a thin-film solar cell module (2) blind holes, which penetrate through the non-transparent layers, and are arranged in a predetermined pattern of holes, the blind holes formed by coating removal by laser beam be and the pulse power and pulse duration of the laser beam can be matched to the material and the thickness of the layers that the coating removal is performed with only one hole per laser pulse.
