Method and apparatus for manufacturing photovoltaic device
First Claim
1. A method of manufacturing a photovoltaic device, comprising:
- a first step of fixing thin metal wires which are coated with electroconductive resin, to a principal surface of a photovoltaic member;
a second step of heating the photovoltaic member to which the thin metal wires are fixed; and
a third step of pressing an elastic film against the photovoltaic member and the thin metal wires while a pressure of first gas on a side opposite the photovoltaic member across the elastic film is larger than a pressure of second gas present in a space between the elastic film and the principal surface of the photovoltaic member.

Abstract
A method of manufacturing a photovoltaic device includes: a step of fixing thin metal wires which are coated with electroconductive resin, to a principal surface of a photovoltaic member; a step of heating the photovoltaic member to which the thin metal wires are fixed; and a step of pressing an elastic film against the photovoltaic member and the thin metal wires while the pressure of gas on the side opposite the photovoltaic member across the elastic film is larger than the pressure of gas on the photovoltaic member side. The thin metal wires to serve as a collector electrode provided in a photovoltaic member are prevented from bending. This makes it possible to produce, with high yield, photovoltaic devices that have no fear of being reduced in output by bent thin metal wires.
