Solar Cell Module and Photovoltaic Power Generator Using This

A solar cell module comprising a plurality of solar cell elements having a plate shape, and arranged between a translucent panel and a back surface protective member such that the solar cell elements are electrically connected to each other by innerleads and spaces between these are filled with a filler member,

• wherein the plurality of solar cell elements each comprises:
• a semiconductor substrate;
• light-receiving surface electrodes on a light receiving surface side of the semiconductor substrate comprising:
• three front surface bus bar electrodes for providing output;
• and
• front surface finger electrodes perpendicular to the front surface bus bar electrodes;
• and
• three back surface bus bar electrodes for providing output on a non-light receiving surface side of the semiconductor substrate,
• wherein, in the plurality of solar cell elements, each of the three front surface bus bar electrodes of one solar cell element is connected by the innerleads to each of the three back surface bus bar electrodes of another solar cell element,
• wherein the front surface bus bar electrodes have widths of not less than 0.5 mm and not more than 2 mm, and the front surface finger electrodes have widths of not less than 0.05 mm and not more than 0.1 mm,
• wherein each of the back surface bus bar electrodes is arranged to be directly below each of the front surface bus bar electrodes with respect to the semiconductor substrate therebetween,
• wherein one of the three front surface bus bar electrodes is disposed on a center line of the semiconductor substrate, and
• wherein neighboring front surface bus bar electrodes are electrically connected to each other via the front surface finger electrodes.
