ABSTRACT:
Laser light having a wavelength where a thin-film semiconductor layer can absorb the laser light is applied on the side of the thin-film semiconductor layer to join a semiconductor-holding member and a metal member by welding. Materials can be joined at a sufficiently high strength and with long term stability especially when a metal member of the same or different type is welded to a conductive substrate which is a part of a photovoltaic device.
