METHOD FOR MANUFACTURING PHOTOVOLTAIC CELLS WITH A REAR SIDE POLYSILICON PASSIVATING CONTACT

摘要

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.
