NOVELTY - The solar cell module has first solar cell (Cell-a) and second solar cell (Cell-b) that each includes first electrodes (C141) formed on back surface of a semiconductor substrate (110), second electrodes (C142) formed in parallel with the first electrodes on back surface of semiconductor substrate, first auxiliary electrode (P141) connected to first electrodes, and second auxiliary electrode (P142) connected to second electrodes. An interconnector (IC) electrically connects the first auxiliary electrode of first solar cell to second auxiliary electrode of second solar cell.    USE - Solar cell module.    ADVANTAGE - Reduces manufacturing cost since unnecessary increase in the thickness is prevented in a state in which minimum resistance is properly secured when thickness of each of the first and second auxiliary electrodes is equal to or less than about 900 micrometers. The thermal expansion stress applied to the semiconductor substrate of solar cell is minimized in the process for manufacturing the cell string of solar cells to manufacture the solar cell module. Minimizes contact resistance between interconnector and first auxiliary electrode pad and contact resistance between interconnector and second auxiliary electrode pad and further increases adhesive strength therebetween since second conductive adhesive is formed between the interconnector and first auxiliary electrode pad and between the interconnector and second auxiliary electrode pad. Increases optical gain by reflecting light incident between the semiconductor substrate of first solar cell and semiconductor substrate of second solar cell and allowing the reflected light to be again incident on the semiconductor substrate of first solar cell and semiconductor substrate of second solar cell through the front glass substrate. The fracture or crack is prevented from being generated in the semiconductor substrate, and at the same time, the resistances of the electrodes formed on the back surface of semiconductor substrate are greatly reduced. Reduces time required in the semiconductor manufacturing process by relatively reducing the thicknesses of first and second electrodes formed on the semiconductor substrate. The bowing phenomenon of semiconductor substrate is minimized and thermal expansion stress of the semiconductor substrate is minimized even if the thickness of electrodes formed on the back surface of semiconductor substrate increase due to the first and second auxiliary electrodes. The efficiency of solar cell module is further improved through increase in the optical gain of solar cell module. The time and yield of the manufacturing process of the solar cell module is further improved.
