Solar cells use as substrates glass (23) coated with a transparent conductive layer (21), able to collect the electric power generated by the solar cell. This layer (21), normally a TCO, have limited conductivity, implying the use of current collector lines applied in a complex manner. The conductivity of the conductive layer (21) is increased by the application of a structure, in particular a grid, of thin conductive lines (22) inserted in grooves on the glass surface (23) or directly applied on this, followed by a TCO layer coating (21). This highly conductive grid (22) collects the electricity from the TCO layer (21) and directs it to the periphery of the cell. Both glass substrates are sealed by a process employing a precursor of glass surrounding the entire perimeter of the substrate. The glass precursor is heated to its melting point, by a laser, completely sealing the two substrates of the module.
