<p>PROBLEM TO BE SOLVED: To provide a solar battery module which enables the suppression of inter-cell shrinkage while ensuring the transparency.SOLUTION: A solar battery module comprises a top protective material 1, a sealant 2, solar battery cells 3, a sealant 4, and a bottom protective material 5, which are laminated in this order; the sealant 2 is laminated on the solar battery cells 3 on the side of their light-receiving surfaces. The quantity of heat of crystal fusionΔH(≥120°C) at or above 120°C measured at a heating rate of 10°C/min in a differential scanning calorimetry on the sealant 2, and the quantity of heat of crystal fusionΔH(≥120°C) at or above 120°C measured at a heating rate of 10°C/min in the differential scanning calorimetry on the sealant 4 satisfy the following conditions (i) to (iii): (i)ΔH(≥120°C)+ΔH(≥120°C)≥3.6 J/g; (ii)ΔH(≥120°C)/ΔH(≥120°C)>1.0; and (iii)ΔH(≥120°C)≥0.4 J/g.</p> |
