Abstract: Method for electrically connecting photovoltaic cells (102) together and for connecting the panels peripherally. The method comprises the use of a flexible film (103) composed of two layers of five materials having different properties. The film (103) has a plurality of through-holes (104) arranged so that they coincide with connection points (107) located on the rear face of the cells (102), so as to allow them to be electrically coupled via the printed macrocircuit (105). The electrical coupling operation is carried out in an automated manner by a lead-free wave soldering method. This method makes it possible for the cost of industrializing solar modules to be considerably reduced, by implementing a continuous method right from the start of the chain up to the lamination step.
