Solar cell and process of manufacturing the same

摘要

A solar cell consisting essentially in a semiconductor substrate having a first region (1) of one conductivity type and a second region (8) of the opposite conductivity type, said substrate being defined by a front radiation receiving surface (2) having a conductive grid and a back surface (3) having separated contacts to the said first region (1) and said second region (8), wherein the conductive grid comprises parallel spaced narrow metal fingers and the contacts to said second region (8) being in the form of wide metal lines connected to the fingers with a limited number of vias (4).
