Abstract: A solar cell module that is one example of an embodiment of the present invention comprises: a plurality of solar cells; a wiring member for connecting adjacent solar cells together; a first protection substrate provided on the light-receiving-surface side of the solar cells; a second protection substrate provided on the rear-surface side of the solar cells; and an encapsulant layer for sealing the solar cells and provided between the first protection substrate and the second protection substrate. The first protection substrate is a resin substrate, and the linear expansion coefficient (α) of the encapsulant layer is 10-250 (10−6/K), and the tensile modulus of elasticity (E) thereof satisfies the condition in Formula 1: 140×exp(0.005α) MPa

Abstract: A solar cell module includes a front surface substrate, a seal layer arranged under the front surface substrate to seal a photoelectric converter, a low thermal expansion-contraction layer arranged under the seal layer, and a rear surface substrate arranged under the low thermal expansion-contraction layer. The solar cell module further includes a stress-reducing resin layer arranged between the low thermal expansion-contraction layer and the rear surface substrate. The low thermal expansion-contraction layer has a smaller coefficient of linear expansion than the rear surface substrate, and the stress-reducing resin layer has a smaller tensile modulus of elasticity than the low thermal expansion-contraction layer and the rear surface substrate.

Abstract: A solar cell module includes a resin substrate, a first resin layer, photoelectric converters, and a second resin layer. The first resin layer is provided under the resin substrate. The photoelectric converters are provided under the first resin layer. The second resin layer is provided under the first resin layer to penetrate the first resin layer or cover the first resin layer from outside to be glued to the resin substrate. Adjacent photoelectric converters are electrically connected to each other by a connecting member. A tensile modulus of elasticity of the first resin layer is lower than that a tensile modulus of elasticity of the resin substrate and a tensile modulus of elasticity of the second resin layer.
