Method of manufacturing an amorphous/crystalline silicon heterojunction solar cell

A method for manufacturing a solar cell includes providing a first conductivity type doped crystalline silicon wafer, depositing on one side a first intrinsic a-Si:H buffer layer, followed by a second conductivity type doped a-Si:H layer, turning over the wafer and depositing on the opposite side a surface passivating anti-reflection coating, applying a first mask having a grid opening on the second conductivity type doped a-Si:H covered surface of the wafer, dry etching to remove the second conductivity type doped a-Si:H layer not covered by the first mask, while maintaining the first mask in position: depositing a second intrinsic buffer layer of a-Si:H, depositing a first conductivity type doped a-Si:H layer
