Abstract: A method for manufacturing a photovoltaic cell from a substrate (2) having a front side (4), a back side (6) and an edge (8). A carrier selective contact structure (4a) of a first type is provided on at least a part of the front side (4). A stack (10) having a thin oxide layer covered by a polysilicon layer is applied, wherein the stack (10) is applied to the back side (6) and the front side (4) of the substrate (2), and possibly also on edge (8). The stack (10) of thin oxide layer and polysilicon layer on the front side (4) is then removed.

Abstract: A solar cell including a semiconductor substrate, having a front side surface for receiving radiation and back-side surface providing a first junction structure in a first area substrate portion and with a second junction structure in a second area substrate portion. The second area portion borders the first area portion. The first junction structure includes a first conductivity type semiconductor layer covering the first area portion. The second junction structure includes a second conductivity type semiconductor layer covering the second area portion. The second junction structure, second conductivity type semiconductor layer partially overlaps the first junction structure, first conductivity type semiconductor layer, with the overlapping second conductivity type semiconductor layer portion being above a first conductivity type semiconductor layer portion while separated by a first dielectric layer.
