SOLAR CELL MODULE AND SOLAR CELL DEVICE

摘要

A solar cell module includes a light-transmitting substrate and solar cell element groups. Each solar cell element group includes solar cell elements aligned in a first direction and each having rectangular first and second surfaces, and a wiring material electrically connecting a first solar cell element and a second solar cell element adjacent to each other in the first direction. The solar cell element groups are aligned in a second direction perpendicular to the first direction. In each solar cell element, first and second side parts each located along the second direction have a length in the second direction larger than the length in the first direction of third and fourth side parts each located along the first direction. The light-transmitting substrate covers the solar cell element groups from the first surface side and has a short side along the first direction and a long side along the second direction.

主权项
