The present invention relates to a solar cell module and a
building-integrated solar cell module having a sealing composition made of
a polymer blend or a polymer alloy. The blend or alloy is made of at least
one polyolefin series copolymer and at least one crystalline polyolefin.
The copolymer has a fusing point Ta by a differential scanning calorimetry
which fall in a range of 50 to 110.degree. C. The crystalline polyolefin
has a fusing point Tb by a differential scanning calorimetry which falls
in a range of from 110 to 170.degree. C.
