<p>PROBLEM TO BE SOLVED: To provide a solar cell complex that achieves a harmony with its surrounding environment and can stably generate power even when an incident direction of external light changes.SOLUTION: A solar cell complex 10 includes a plurality of unit lenses 30 arranged in a first axis direction d1, a sheet type main body 40 where the plurality of unit lenses is disposed, and a solar cell panel 50 disposed on an opposite side to the unit lenses referring to the main body. A plurality of optical functional faces 12 is arranged in the first axis direction to be located between the corresponding unit lens and the solar cell panel. The unit lens guides light incident in a given direction toward the solar cell panel through a region 60 between adjoining two optical functional faces, and guides light incident in another direction different from the given direction toward the optical functional face. An exit face 41 where the light incident to the unit lens in the given direction and propagating toward the solar cell panel exits inclines with respect to the sheet surface of the main body.</p> |
