Abstract:
1. A solar module comprising: a bifacial light-receiving solar cell, a transparent member that reflects light arranged on the light-receiving surface side of the solar cell, a weather-resistant member arranged on the back surface side of the solar cell, and a bonding layer arranged in a space between the transparent member and the weather-resistant member; wherein the bonding layer including at least two media with different refractive indices, interfaces are formed by at least two media and are positioned in a region unoccupied by the solar cells, and the interfaces being configured such that at least some of the light that is incident on the interfaces in a direction perpendicular to the solar module is refracted at the interfaces towards the solar cells, reflected on the weather-resistant member, and guided to the back surface of the solar cells.
