Abstract
A manufacturing method of an embodiment according to the present invention may comprise the steps of: locating a solar cell, including a semiconductor substrate and a semiconductor layer which has an absorption coefficient higher than that of the semiconductor substrate and is formed on at least one side of the semiconductor substrate, such that the semiconductor layer is oriented toward a laser; emitting a laser beam toward the semiconductor layer to form a groove on the solar cell; and dividing the solar cell along the groove into a plurality of pieces.
Claims13
A method for fabricating a solar cell, the method comprising:
- positioning a semiconductor substrate and a semiconductor layer with a higher absorption coefficient than the semiconductor substrate in such a manner that the semiconductor layer faces a laser in a solar cell formed on at least one side of the semiconductor substrate;
- forming a groove in the solar cell by directing the laser toward the semiconductor layer;
- and
- dividing the solar cell into multiple sections along the groove.
