A solar cell system for generating electricity by absorbing sunlight, comprising a laminated structure and a power generation cell disposed in a peripheral area of the laminated structure, wherein, in the laminated structure, a transparent sheet member comprising a wavelength conversion material and a first transparent sheet are laminated, a maximum emission wavelength of the wavelength conversion material is 780 nm or more, and a refractive index na1 of the first transparent sheet is higher than a refractive index nb of the transparent sheet member. According to the present invention, can provide a solar cell system including a power generation cell and a transparent layer capable of efficiently guiding light to a side surface, wherein, inside the transparent layer, light having been incident on a surface of the transparent layer is converted into light with a long wavelength, such as near infrared radiation. |
