Problem to be solved: the invention relates to thin-film photovoltaic modules which are made semi-transparent by laser ablation or by lithography processes. The transparency areas (6) form a network of repetitive patterns such as a network of circular or hexagonal holes. The electrical insulation lines (P1, P3) and the electrical interconnection lines P2 between the cells are positioned at randomeither in the transparency areas (6) or in the non-transparency areas, and demonstrate visual effects which reduce the homogeneous quality of said photovoltaic module. The solution to said problem isas follows: in order to make them invisible to the naked eye, said electrical insulation lines P1 and P3 are positioned in transparency areas (6) arranged in straight bands (7, 8) having high transparency density, and the electrical interconnection lines P2 are positioned in transparency areas (6) arranged in straight bands (9) having low transparency density.
