PROBLEM TO BE SOLVED: To provide a solar cell structure capable of increasing the amount of power generation while retaining design quality.SOLUTION: In a solar cell structure 100, a structure 10 has flat parts 12a, 12b and a level-difference part 14. A light guide layer 30 covers the flat parts 12a, 12b and the level-difference part 14. A photoelectric conversion unit 20 is provided on the light guide layer 30 covering the flat part 12a. The light guide layer 30 guides incident light thereupon into the photoelectric conversion unit 20. A light control layer 34 is provided on the light guide layer 30 and used to control the direction of light entering toward the light guide layer 30. The light control layer 34 is provided with an orientation layer provided on the light guide layer 30 and a light condensation layer provided on the orientation layer, the light condensation layer condensing incident light toward the light guide layer 30, and the orientation layer changing the direction of light condensed by the light condensation layer to a direction in which the light guide layer 30 extends. |
