ABSTRACT:
In a photovoltaic device comprising a conductive base plate having four side edges, at least one conductive foil having a higher conductivity than the conductive base plate is provided in contact with the conductive base plate along at least one side edge of the conductive base plate. The conductive foil is preferably provided on the non-light-receiving surface of the photovoltaic device, and comprises copper as a main ingredient. The conductive foil preferably has a thickness in the range of 70 .mu.m to 150 .mu.m and is provided along each of two side edges of the conductive base plate facing each other. The conductive base plate is a base plate made of stainless steel. In the photovoltaic device and a manufacture method thereof, the conductive foil and the conductive base plate are connected together by ultrasonic welding.
