<P>PROBLEM TO BE SOLVED: To provide a solar cell module improved the light use efficiency by effectively reusing light that is lost in nature. <P>SOLUTION: The solar cell module 200 includes a light reuse sheet 20. The light reuse sheet 20 includes a base 2 and a reflection layer 3. A plurality of convex portions 201 for reflection is formed on the reflection layer 3 along a flat plane that is parallel to a plane P that is parallel to the light incident plane 110 of a front plate 22. The convex portion 201 includes a curved reflection plane having such a shape that the cross sectional area in the plane parallel to the flat plane P that is parallel to the light incident plane 110 is reduced as the front plate 22 gets closer in the convex direction of the convex portion 201. <P>COPYRIGHT: (C)2010,JPO&INPIT |
