Abstract

A solar cell module that includes a plurality of solar cells each of which has a photoelectric conversion body configured to generate carriers upon exposure to light; and an electrode provided on the main surface of the photoelectric conversion body, and configured to collect the carriers from the photoelectric conversion body; a wiring member configured to electrically connect the plurality of solar cells; and a wiring substrate that covers main surfaces of at least two or more solar cells out of the plurality of solar cells, the wiring substrate comprising a groove provided along at least a part of the electrodes, wherein a conductive member is provided at a bottom of the groove, and the conductive member electrically connects the electrodes to the wiring member.

Claims

1. A solar cell module comprising:

a plurality of solar cells each comprising;

a photoelectric conversion body that generates carriers upon exposure to light; and

an electrode provided on a main surface of the photoelectric conversion body, which collects the carriers from the photoelectric conversion body;

a wiring member that electrically connects the plurality of solar cells; and

a wiring substrate that covers the main surfaces of at least two or more solar cells out of the plurality of solar cells, the wiring substrate comprising a groove provided along at least a part of the electrodes, wherein

a conductive member is provided at the bottom of the groove, and

the conductive member electrically connects the electrodes to the wiring member.

2. The solar cell module of claim 1, further comprising a linear solar cell array comprised of a group of solar cells electrically connected to each other by the wiring member in a predetermined arrangement direction, wherein

the width of the wiring substrate is smaller than the width of the solar cell string.

3. The solar cell module of claim 1, wherein

the wiring member is provided inside the groove.

4. The solar cell module of claim 1, wherein

the groove is provided to extend continuously across at least two or more solar cells, and the wiring member is provided inside the groove.

5. The solar cell module of claim 1, wherein

the wiring member electrically connects at least two or more solar cells to each other.

6. The solar cell module of claim 1, further comprising an elastic member provided between the bottom of the groove and the conductive member.

7. The solar cell module of claim 1, further comprising a plurality of solar cell arrays, each comprised of a group of solar cells electrically connected to each other by the wiring member in a predetermined arrangement direction, wherein

the plurality of solar cell arrays include a first solar cell array and a second solar cell array adjacent to the first solar cell array;

a first solar cell provided at one end of the first solar cell array is electrically connected to a second solar cell provided at one end of the second solar cell array by the wiring member; and

the wiring substrate covers the main surface of the first solar cell and the main surface of the second solar cell.
