SOLAR CELLS CONSIST OF LAYERS OF FOAM AND A CONDUCTIVE SUBSTANCE THAT PASSES THROUGH THESE LAYERS.

Abstract

The invention relates to a solar cell (la) comprising a set of stacked foam layers (12), a support layer (2) for easy removal, and a conductive medium (7) passing through the foam layers. The set of stacked foam layers (12) comprises a photoabsorbing layer (3), a first conductive layer (4) comprising a conductive material to carry the electrons released from the photoelectric process at the photoabsorbing layer (3), a counter electrode layer (6) comprising a conductive material and a separating layer (5) made of insulating foam material and arranged between the first conductive layer (4) and the counter electrode layer (tì), and where the first conductive layer (4) is arranged closer to the photoabsorbing layer (3) than to the counter electrode layer (6). The support layer (2) and the conductive medium (7) pass through the support layer (2).
