Abstract:
A thin-layer solar cell array system including a solar cell layer placed over a planar substrate and provided with at least one n-type semiconductor zone and at least one p-type semiconductor zone, first and a second contact electrodes respectively of different electrical polarity and respectively connected to the n-type semiconductor zone and to the p-type semiconductor zone wherein:an electrical insulation layer is disposed on the planar substrate on which the first and second contact electrodes are disposed; the first contact electrode faces and is under the solar cell layer; the solar cell layer is separated from the first and second contact electrodes; at least one first contact channel extends at least through the solar cell layer so that the first contact electrode and the n-type semiconductor zone are electrically connected by an electrically conductive material inside the at least one first contact channel; the second electrical contact electrode faces and is under the solar cell layer and is spaced from and electrically insulated from the first contact electrode; and at least one second contact channel extends at least through the solar cell layer so that the second contact electrode and the at least one p-type semiconductor zone are electrically connected by an electrically conductive material inside the at least one second contact channel.
