Patent attributes
This invention is made to improve the characteristics of a photovoltaic module in which a plurality of solar cells are electrically connected to each other with connecting members such as tabs or connecting leads. The present invention provides a method for manufacturing a photovoltaic module comprising a plurality solar cells each including a semiconductor heterojunction made by combining amorphous silicon and crystalline silicon and connecting members for connecting the plurality solar cells in which the connecting members are connected to the solar cells by soldering after a high-temperature heat treatment is applied to the solar cells, and the plurality of solar cells are electrically connected to each other with the connecting members.
