Abstract: A solar cell module and a method of manufacturing the same are provided. The method of manufacturing a solar cell module includes forming a plurality of strings to which a plurality of solar cells are connected; disposing a target string at a repair device, the target string including a target solar cell having a defect; separating the target solar cell from the target string by selectively thermally processing a connection area of a target intercell connector and the plurality of conductive wirings fixed to the target solar cell; disposing a new solar cell at the target string; and connecting the plurality of conductive wirings fixed to the new solar cell to the target intercell connector.

Abstract: A solar cell module and a method for manufacturing the same are discussed. The solar cell module includes a plurality of solar cells each including a semiconductor substrate and first and second electrodes, each of which has a different polarity and is extended in a first direction on a back surface of the semiconductor substrate, and a plurality of conductive lines extended in a second direction crossing the first direction on the back surface of the semiconductor substrate, connected to one of the first and second electrodes through a conductive adhesive, and insulated from the other electrode by an insulating layer. The conductive adhesive includes a first adhesive layer connected to the one electrode and a second adhesive layer positioned on the first adhesive layer and connected to the plurality of conductive lines.
