Designable shingled photovoltaic module and manufacturing method therefor

A method of manufacturing a designable shingled photovoltaic module having a designable shingled string structure, the method comprising:

• operation (a) of preparing a solar cell having a front surface on which a finger electrode and a busbar electrode are formed and a rear surface on which a rear surface electrode is formed;
• operation (b) of cutting the solar cell in a rectangular shape through a laser scribing process to divide the solar cell into a plurality of unit cells;
• and
• operation (c) of connecting the unit cells to have a shingled array structure in which a short side of any one divide unit cell overlaps a short side of another divided unit cell,
• wherein, in operation (a), the finger electrode is disposed as a plurality of finger electrodes in a first direction parallel to the short side of the divided unit cell, and
• the busbar electrode includes a collection electrode line which extends in a second direction parallel to a long side of the divided unit cell and connects ends of the plurality of finger electrodes and a connecting electrode line which is branched off from an end of the collection electrode line and extends in the first direction to be electrically connected to another unit cell to be connected.

A method of manufacturing a designable shingled photovoltaic module, the method comprising:

• (a) forming a solar cell in which a front surface electrode, a finger electrode, and a rear surface electrode are formed on a semiconductor substrate and dividing the solar cell into a plurality of unit cells by cutting the solar cell along cut lines in a checkerboard shape;
• (b) forming strings by connecting the divided unit cells in a shingled manner;
• and
• (c) forming a photovoltaic module by connecting the plurality of strings using a conductive wire embedded in a flexible connecting wire,
• wherein the forming of the photovoltaic module includes applying an electrically conductive adhesive on electrodes of the unit cells formed at two sides of the strings and electrically connecting the electrodes and the conductive wire through a curing process performed as a thermal process in a state in which the conductive wire is disposed.
