易に理解できる。A feature of the present invention is that a plurality of V-shaped grooves are arranged on the surface of the substrate (1) so as to be aligned from the ridge toward the eaves. That is, by disposing the V-shaped groove on the surface of the substrate (1), the surface area of the substrate (1) is increased and the heat dissipation is improved. Further, by providing the groove in the direction from the ridge to the eaves, rainwater and the like can quickly flow through the groove, and at the same time, dust and the like accumulated in the groove can be effectively washed away. Therefore, the solar cell roof tile of the present invention can suppress the output decrease due to the high temperature of the solar cell by improving the heat dissipation, and the rainwater flowing through the groove of the roof tile can effectively wash away dust etc. You can prevent the decline. Further, when the apex angle of the groove is formed to be 20 to 90 °, the light reflected by the surface of the substrate (1) can be irradiated again on the opposite slopes to be incident on the substrate (1), so that the sunlight is effective. Can be used for. For example, the groove of the roof tile of the present invention has a depth of 2 mm and an apex angle of 50 °, and the direction of the irradiation light is a film-like photoelectric conversion element (2).
When it is perpendicular to the plane, the reflection loss is about 0.02%, which is much smaller than the reflection loss of 4% of the prior art roof tile under the same irradiation conditions. Further, at this time, the surface area of the roof tile of the present invention is about 2.3 times that of the conventional roof tile, and it can be easily understood that the heat dissipation of the roof tile is improved.

Since the surface area is increased, the heat dissipation of the roof tiles is improved, and as a result, the temperature rise of the solar cell is suppressed, the output reduction due to high temperature can be prevented, and rainwater etc. accumulates in the groove quickly. Dust and the like are effectively removed, and it is possible to prevent a decrease in the irradiation light amount due to dust and the like covering the roof tile surface.
