  • Publication number: 20140014182
    Abstract: The present invention relates to a solar cell module which is characterized in that: a light-transmitting elastomer member and a solar cell element are arranged in a space between a panel of a transparent member upon which sunlight is incident and a panel of a thermally conductive member which is arranged on the side opposite to the sunlight incidence side in such a manner that the light-transmitting elastomer member is closer to the sunlight incidence side; and the solar cell element is pressed by the light-transmitting elastomer member toward the panel of a thermally conductive member so that the solar cell element is compression bonded thereto. This solar cell module is most suitable as a solar cell module that has excellent heat dissipation of a cell, the temperature of which is increased due to sunlight or a hot spot, and a structure that suppresses the production cost.
