Method for manufacturing photovoltaic module and photovoltaic module

A method for manufacturing a photovoltaic module, comprising:

• providing a plurality of solar cells and a solder strip, wherein the solar cells are back contact solar cells;
• applying an insulating adhesive on a rear surface of the solar cells;
• laying the plurality of solar cells in sequence along a first direction;
• placing the solder strip on the solar cells so that, along the first direction, one end of the solder strip abuts against a positive busbar of one of the solar cells, and at least part of the one end of the solder strip is bonded to the insulating adhesive on the solar cells, and the other end of the solder strip abuts against a negative busbar of another one of the solar cells adjacent thereto, and at least part of the other end of the solder strip is bonded to the insulating adhesive on the solar cells;
• curing the insulating adhesive by irradiation with an ultraviolet lamp to fixedly connect the solder strip to the solar cells, so that the plurality of solar cells are connected through the solder strip to form a solar cell string;
• arranging a plurality of formed solar cell strings along a second direction, and connecting two adjacent solar cell strings in series and/or in parallel to form a photovoltaic cell pack, wherein the second direction is perpendicular to the first direction;
• providing a front packaging structure and a back packaging structure;
• and
• arranging the front packaging structure on a front surface of the photovoltaic cell pack, arranging the back packaging structure on a rear surface of the photovoltaic cell pack, and laminating the front packaging structure, the photovoltaic cell pack, and the back packaging structure to form the photovoltaic module,
• wherein, subsequent to the applying an insulating adhesive on a rear surface of the solar cells and prior to the laying the plurality of solar cells in sequence along a first direction, the method further comprises:
• performing adhesive deviation inspection to the solar cells on which the insulating adhesive is applied;
• and
• performing appearance inspection to the solar cells, and
• wherein, subsequent to the performing appearance inspection to the solar cells, the method further comprises:
• scribing each of the solar cells into half-cut cells;
• and
• performing front appearance inspection and back appearance inspection to the half-cut cells.
