Abstract
The present invention relates to a method and apparatus for manufacturing a solar cell module using a laser. In the present invention, a tabbing process for bonding a solar cell and metal electrodes is performed by a local irradiation with a laser, so that the heating area can be localized only to a required zone (bonding area) for the tabbing process, thereby minimizing a direct heating zone which occurs in the process. Therefore, it is possible to reduce the damage such as cracks and breakage due to thermal expansion/contraction of a solar cell which is conventionally configured to have a multi-layered structure made of different materials, to improve the bonding strength and the bonding uniformity, and to reduce the processing time, thereby improving the production efficiency.
