This solar cell module (1) has: a light collector unit (10); a first light guide unit (20) provided along the first end surface (10c) of the light collector unit; and a first solar cell element (30) provided to an end in the direction of extension of the first light guide unit. The light collector unit has a first surface and a second surface that border the first end surface. The light collector unit is configured in a manner so as to collect and emit the light that enters to the interior thereof from the first surface at at least the first end surface by causing propagation through the interior. The first light guide unit is configured in a manner so as to cause light emitted from the first end surface of the light collector unit: to enter the interior from the connection surface (20x) between the first light guide unit and the first end surface; to be propagated in the direction of extension of the first light guide unit; to be emitted from the aforementioned end; and to enter the first solar cell element. At least the second surface of the light collector unit is provided with a plurality of first reflection sections (18) that reflect light entering from the first surface, and that, in the in-plane direction of the first surface, alter the direction of progress of the light that has entered to a direction that obliquely intersects with the direction of extension of the first end surface. The solar cell module is able to use a solar cell having a size corresponding to that of the end surface of the first light guide unit, and achieves a high power generation efficiency at a low cost. |
