Abstract: A solar cell module includes a plurality of solar cells, each solar cell including a semiconductor substrate, an emitter region, a back surface field region a first electrode connected to the emitter region, a second electrode connected to the back surface field region, and a conductive line connected to one electrode of the first and second electrodes using a conductive adhesive and insulated from the other electrode of the first and second electrodes through an insulating layer, the conductive line being used to connect a plurality of solar cells in series. A thickness of the conductive adhesive between the one electrode and the conductive line is greater than a thickness of the insulating layer between the other electrode and the conductive line.
