Abstract: The invention relates to a thin film solar module comprising a monolithic solar cell array (1), including a plurality of solar cells (2) with a layer structure, comprising a rear contact layer (3), a front contact layer (4) and an absorber layer between the rear contact layer and the front contact layer, and an electrical connection structure (6) for electrically serially connecting neighbouring solar cells. The invention also relates to an associated production method. In the thin film solar module according to the invention, the electrical connection structure includes contact strips (7) for electrically serially connecting neighbouring solar cells, wherein the electrical connection structure electrically serially connects two respective solar cells (2m, 2m+1) that are adjacent to one another in a series connection direction (RS) via one or more contact strips (7).
