Patent ID: 8063299

Claim:
A solar battery module comprising: a light penetrable sheet member; a sheet member; plate-like solar cells held between said light penetrable sheet member on a light receiving surface side and said sheet member on a back surface side with internal apertures therebetween filled with a sealing resin; wherein said plate like solar cells have a generally rectangular shape, except that each of its four corners is cut-off at an approximately 45° angle; and a plurality of light diffusion sections diffusely reflecting light and arranged along each cut-off corner on an invalid region of each solar cell, wherein the light diffusion sections are arranged on the invalid region positioned on the light receiving surface side of the solar cell, and the light diffusion sections diffuse and reflect light to the light penetrable sheet member side, wherein a connection member for electrically connecting the adjacent solar cells is arranged on the invalid region of said solar cells, and the light diffusion section is arranged on a light receiving surface side of the connection member; wherein said light diffusion sections along with said light penetrable sheet member are designed to reflect light to a solar cell which is immediately adjacent to said light diffusion sections; wherein said connection member is located on and in contact with a bus electrode and wherein said connection member runs parallel, directly above said bus electrode.
