G. Electromagnetic radiation, for example, a method is provided in order to convert solar energy into electrical energy and a device to increase the efficiency compared to conventional solar cells. The photovoltaic (PV) devices are typically window layer; The photons to be moved over the window layer, and electrons are generated at the time to be absorbed by the absorber layer, a window layer disposed on the lower absorbent layer; And a plurality of contact for external connection connected to the absorbent layer comprises a (contact point for the external connection are arranged on the lower the absorption layer, the photons do not block up to the absorption layer through the window layer). By placing all of the contacts on the rear side of the PV device, typically a solar shadow generated by the front-side contact is found in the conventional solar cell is prevented. Therefore, a PV device having a rear-side contact point described herein can increase the efficiency compared to conventional solar cells.
