A solar module having improved photoelectric conversion efficiency is provided. The solar module (1) is provided with a bifacial light-receiving solar cell (10), a transparent member (15), a weather-resistant member (14), and a bonding layer (13). The bonding layer (13) includes at least two media (13b, 13c) having different refractive indices. Interfaces (22, 23) are formed by at least two media (13b, 13c) and are positioned in a region unoccupied by the solar cells (10). The interfaces (22, 23) are configured such that at least some of the light that is incident on the interfaces (22, 23) in a direction (z) perpendicular to the solar module (1) is guided to the back surface (10b) of the solar cells (10). |
