摘要： In a solar cell including a photoelectric conversion layer 14 disposed on a flexible substrate 11 and constituted by a laminated layer of non-single crystalline silicon thin films, the flexible substrate 11 has a coefficient of linear thermal expansion of is 2.0 ppm to 10.0 ppm. By this, the coefficient of linear thermal expansion of the flexible substrate 11 and that of the photoelectric conversion layer 14 become close to each other, so that warp and deformation during manufacturing steps and after the steps are decreased. Further, since stress applied to the photoelectric conversion layer 14 is also lessened, the photoelectric conversion efficiency can be increased.
