Claim:
1. A method for manufacturing a solar cell module comprising: preparing a plurality of solar cells each having a plurality of first electrodes and a plurality of second electrodes positioned in parallel with each other on a back surface of a semiconductor substrate; and connecting a first conductive line to the plurality of first electrodes included in each of the plurality of solar cells using a conductive adhesive and a second conductive line to the plurality of second electrodes included in each of the plurality of solar cells using the conductive adhesive by a first thermal process; interconnecting the first conductive line of a first solar cell of the plurality of solar cells to an interconnector and the second conductive line of a second solar cell of the plurality of solar cells, which is adjacent to the first solar cell, to the interconnector by a second thermal process; and laminating the plurality of the solar cells between a first encapsulant layer and a second encapsulant layer; wherein the interconnector is located between the first solar cell and the second solar cell, wherein a plurality of first connection points are positioned in a portion where the plurality of first electrodes and the first conductive line cross or overlap each other, and a plurality of second connection points are positioned in a portion where the plurality of second electrodes and the second conductive line cross or overlap each other, wherein the first thermal process of the connecting includes: a temporary attachment process at a first maximum temperature; and a main attachment process at a second maximum temperature higher than the first maximum temperature, and wherein the main attachment process is performed along with the laminating.
