Abstract

A concentrating solar cell module including; a base portion having a plurality of mounting regions for mounting solar cells and a plurality of lead electrodes for electrically connecting the solar cells with external electrodes; a support composed of a thermosetting resin, the support surrounding each of the mounting regions of the base portion; the solar cells mounted on the mounting regions; and a condensing lens molded above the mounting regions so as to encapsulate the solar cells, wherein a surface of the mounting regions of the base portion is plated, the condensing lens is molded with a transparent thermosetting silicone resin, and the support is joined to a surface of the base portion, the surface to which the support is joined is on the same side of the base portion as the surface on which the solar cells are mounted.

First claim

What is claimed is:

1. A concentrating solar cell module comprising:
a base portion having a plurality of mounting regions for mounting solar cells and a plurality of lead electrodes for electrically connecting the solar cells with external electrodes;
a support composed of a thermosetting resin, the support surrounding each of the mounting regions of the base portion;
the solar cells mounted on the mounting regions; and
a condensing lens molded above each of the mounting regions so as to encapsulate the solar cells,
wherein a surface of each of the mounting regions of the base portion is plated, the condensing lenses are molded with a transparent thermosetting silicone resin, and the support is joined to a surface of the base portion, the surface to which the support is joined is on the same side of the base portion as the surface on which the solar cells are mounted, and
wherein the concentrating solar cell module has a half dicing structure in which only a portion of the base portion is cut or the base portion and only a portion of the support are cut from a backside of the concentrating solar cell module.

2. The concentrating solar cell module according to claim 1 , wherein the support is molded with a thermosetting resin that contains a silicone resin and has a reflectance of 90% or more with respect to a light with a wavelength ranging from 350 nm to 900 nm.

3. The concentrating solar cell module according to claim 1 , wherein an inner wall surface of the support is coated with metal by vapor deposition or plating.

4. The concentrating solar cell module according to claim 2 , wherein an inner wall surface of the support is coated with metal by vapor deposition or plating.

5. The concentrating solar cell module according to claim 1 , wherein the support has an upper portion extending toward a center of the mounting region.

6. The concentrating solar cell module according to claim 4 , wherein the support has an upper portion extending toward a center of the mounting region.

7. The concentrating solar cell module according to claim 1 , wherein the mounted solar cells are connected to the respective plated mounting regions through a metal or a conductive thermosetting silicone resin.

8. The concentrating solar cell module according to claim 6 , wherein the mounted solar cells are connected to the respective plated mounting regions through a metal or a conductive thermosetting silicone resin.

9. The concentrating solar cell module according to claim 1 , wherein the support is formed from at least one material selected from a thermosetting silicone resin, an organic modified silicone resin, and a mixed resin of an epoxy resin and a silicone resin.

10. The concentrating solar cell module according to claim 1 , wherein the support contains at least one selected from the group consisting of a filler, a dispersing agent, a pigment, a fluorescent substance, a reflective substance, a light-shielding substance, and a fibrous inorganic material.
