Abstract

A method for producing a concentrating solar cell module having the steps of: preparing 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, and a support composed of a thermosetting resin, the support surrounding each of the mounting regions of the base portion; mounting the solar cells on the mounting regions; molding a condensing lens above the mounting regions so as to encapsulate the solar cells, plating a surface of the mounting regions of the prepared base portion after the preparing step and before the mounting step; and joining the support to the base portion after the mounting step and before the molding step, wherein in the molding step, the condensing lens is molded with a transparent thermosetting silicone resin.

First claim

What is claimed is:

1. A method for producing a concentrating solar cell module comprising the steps of:
preparing 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, and a support composed of a thermosetting resin, the support surrounding each of the mounting regions of the base portion;
mounting the solar cells on the mounting regions;
molding a condensing lens above the mounting regions so as to encapsulate the solar cells,
plating a surface of the mounting regions of the prepared base portion after the preparing step and before the mounting step; and
joining the support to a surface of the base portion after the mounting step and before the molding step, 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, so that the support surrounds each of the mounting regions on which the solar cells are mounted, wherein
in the molding step, the condensing lens is molded with a transparent thermosetting silicone resin.

2. The method for producing a concentrating solar cell module according to claim 1 , wherein, the support joined to the base portion in the joining step has an inner wall surface coated with metal by vapor deposition or plating.

3. The method for producing a concentrating solar cell module according to claim 1 , wherein the support prepared in the preparing step has an upper portion extending toward a center of each mounting region of the plurality of mounting regions.

4. The method for producing a concentrating solar cell module according to claim 2 , wherein the support prepared in the preparing step has an upper portion extending toward a center of each mounting region of the plurality of mounting regions.

5. The method for producing a concentrating solar cell module according to claim 1 , wherein in the mounting step, the solar cells being mounted are connected to the respective plated mounting regions through a metal or a conductive thermosetting silicone resin.

6. The method for producing a concentrating solar cell module according to claim 4 , wherein in the mounting step, the solar cells being mounted are connected to the respective plated mounting regions through a metal or a conductive thermosetting silicone resin.

7. The method for producing a concentrating solar cell module according to claim 1 , wherein, after the molding step, only a portion of the base portion is cut or the base portion and only a portion of the support are cut to form a half dicing structure to form an electric circuit.

8. The method for producing a concentrating solar cell module according to claim 6 , wherein, after the molding step, only a portion of the base portion is cut or the base portion and only a portion of the support are cut to form a half dicing structure to form an electric circuit.

9. The method for producing a concentrating solar cell module according to claim 1 , wherein, in the molding step, the condensing lens is molded by compression molding, transfer molding, injection molding, or cast molding.

10. The method for producing a concentrating solar cell module according to claim 1 , wherein, after the molding step, the concentrating solar cell module is cut by dicing into individual concentrating solar cell modules.

11. A method for producing a concentrating solar cell module comprising the steps of:
preparing 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, and a support composed of a thermosetting resin, the support surrounding each of the mounting regions of the base portion;
mounting the solar cells on the mounting regions;
molding a condensing lens above the mounting regions so as to encapsulate the solar cells,
plating a surface of the mounting regions of the prepared base portion after the preparing step and before the mounting step; and
joining the support to a surface of the base portion after the mounting step and before the molding step, 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, so that the support surrounds each of the mounting regions on which the solar cells are mounted, wherein
in the molding step, the condensing lens is molded with a transparent thermosetting silicone resin, and
after the molding step, only a portion of the base portion is cut to form a half dicing structure or the base portion and only a portion of the support are cut to form a half dicing structure, to form an electric circuit.
