Abstract

The present invention concerns a bifacial solar cell (1) comprising a front side (10) and a back side (20), said front and back sides (10, 20) having a respective outer layer (34) made of transparent conductive oxide, on which is placed a respective metallization grid (11, 21), each metallization grid (11, 21) comprising first collectors (111, 211) running parallel to each other in a horizontal direction (x) of said solar cell (1) and second collectors (112, 212) crossing said first collectors (111, 211), each second collector (112, 212) comprising two vertical elements (112a, 112b, 212a, 212b) and at least one horizontal element (112c, 212c) every one or two first collectors (111) or 3 or 6 first collectors (211) connecting said two vertical elements (112a, 112b, 212a, 212b), said solar cell module being characterized in that said metallization grids (11, 21) furtherly comprise at least one respective front or back area (113, 213), said front or back area (113, 213) comprising said at least one horizontal element (112c, 212c) and a portion of the underlying outer layer (34) made of transparent conductive oxide, so that a cell connector can be attached to said solar cell (1) by mea…
