LIGHT REUSE SHEET AND SOLAR BATTERY MODULE

摘要

A light reuse sheet includes: a reflection forming layer having an uneven portion including a first inclined portion and a second inclined portion; and a reflecting surface provided at a surface of the uneven portion. The light reuse sheet generates second light by reflecting first light toward a front plate, the first light being transmitted through a filling layer without being received by a light receiving face of a solar battery cell, the light reuse sheet generates third light by reflecting the second light at an interface between a light incident surface and outside of the front plate, and the light reuse sheet causes the third light to be incident to the light receiving face of the solar battery cell.
