Abstract

It is an object of the present invention to easily and inexpensively provide a structure of effectively utilizing a light incident on an invalid area of a solar cell. Moreover, it is another object to improve output characteristics of the solar cell by effectively utilizing the light. The gist of the present invention resides in a solar battery module in which plate-like solar cells are held between a light penetrable sheet member on a light receiving surface side and a sheet member on a back surface side, and internal apertures are filled with a sealing resin, wherein a light diffusion section for diffusely reflecting a light or a light diffusion section of a white color is arranged in an invalid region of each solar cell.

Claims

1. A solar battery module in which plate-like solar cells are held between a light penetrable sheet member on a light receiving surface side and a sheet member on a back surface side, and internal apertures are filled with a sealing resin, wherein

a light diffusion section for diffusely reflecting a light or a light diffusion section of a white color is arranged in an invalid region of each solar cell.

2. The solar battery module according to claim 1, wherein a connection member for electrically connecting the adjacent solar cells is arranged in the invalid region, and the light diffusion section is arranged on a light receiving surface side of the connection member.
