Abstract
In order to provide a see-through solar cell module in which the manufacturing costs can be reduced and transmittance can be readily modified without modifying the manufacturing steps, there is provided a solar cell module comprising solar cells in which are layered a conductive substrate, and a lower electrode layer, a photoelectric conversion layer, and an upper electrode layer in the stated order on the conductive substrate; the solar cell module having a configuration in which a plurality of through-openings that pass through the conductive substrate to the upper electrode layer in the layering direction is formed over the entire surface of the solar cells.
Claims7
A solar cell module comprising:
- first and second solar cells each including
- a conductive substrate,
- a lower electrode layer being disposed next to conductive substrate,
- a photoelectric conversion layer, and
- an upper electrode layer, with the photoelectric conversion layer being disposed between the lower electrode layer and the upper electrode layer;
- a plurality of through-openings extending through the conductive substrate of the first solar cell to the upper electrode layer of the first solar cell;
- and
- an electrical connector electrically connecting the first and second solar cells, the electrical connector being disposed between a surface of the upper electrode layer of the first solar cell and a surface of the conductive substrate of the second solar cell,
- the through-openings being arranged on the first solar cell such that a ratio of opening region of the through-openings per unit area of the first solar cell increases as moving away from the electrical connector along the first solar cell.
