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.

This highly conductive grid (22) collects the electricity from the TCO layer (21) and directs it to the periphery of the cell.
