<p><P>PROBLEM TO BE SOLVED: To provide a solar cell module provided with an insulating substrate controlling the generation of warpage in the solar cell module. <P>SOLUTION: The solar cell module 1 has: a translucent substrate 2; a plurality of solar cells 5; and the insulating substrate 3 containing an electric wiring, wherein the plurality of cells 5 are sealed by a sealing layer 6 between the translucent substrate 2 and the insulating substrate 3. The translucent substrate 3 is a glass panel with a thickness of 2-4 mm, and the solar cells 5 are crystalline solar cells with a thickness of not more than 100-300μm which are arranged staggered via gaps. This solar cell module 1 satisfies following formulas when the warpage (unit:μm) of the solar module 1 is Y, and the product of the elastic modulus E (unit: GPa) and the thermal expansion coefficientα(unit: ppm) of the insulating substrate 3 is X. A formula (1): Y≤12.88X+521.7. A formula (2): Y≥0.0324X+83.69. A formula (3): Y≤1,000, X≤700. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
