<p><P>PROBLEM TO BE SOLVED: To provide a solar cell module that improves the efficiency of light use by effectively reusing light which is otherwise a loss. <P>SOLUTION: In a solar cell module 200 having an optical reuse sheet 20, the optical reuse sheet 20 has a base material 2 and a reflection forming layer 3, and in an upper surface of the reflection forming layer 3, a plurality of recesses 201 for reflection are formed along a plane parallel to a plane P which is parallel to an optical injection surface 110 of a front board 22. The recess 201 constitutes a curved reflection surface showing a shape wherein a cross-sectional area in a surface parallel to the plane P parallel to the optical injection surface 110 is enlarged as it comes close to the front board 22 side in a projection direction of the recess 201. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
