A solar cell module of the present invention was made to improve adhesion between electrodes, which is formed with thermosetting resin containing silver paste, of a solar cell element and connecting tabs coated with lead (Pb) free solder. To achieve this purpose, the solar cell module is comprised of a front surface member, a rear surface protective member, a plurality of solar cell elements provided between the front surface member and the rear surface protective member, and connecting tabs for electrically connecting the solar cell elements to each other through electrodes with the use of lead free solder. The electrodes of the solar cell elements are made of silver paste containing thermosetting resin and silver powder. The thermosetting resin contains epoxy resin at volume ratio of 70% or more having a glass transition rate of 80° C. to 200° C. measured by a TMA method. The connecting tabs coated with lead free solder are soldered to the electrodes. |
