Electric double-layer capacitor and solar power generation device

A solar power generation device comprising:

• an electric double-layer capacitor comprising:
• a first current collector including a light-transmitting conductive material;
• a second current collector including a light-transmitting conductive material;
• first active materials comprising activated carbon or a polyacenic material, which are dispersed on a surface of the first current collector;
• second active materials comprising activated carbon or a polyacenic material, which are dispersed on a surface of the second current collector;
• a light-transmitting electrolyte layer between the first current collector and the second current collector so that the first active materials and the second active materials are provided on the light-transmitting electrolyte layer side;
• and
• a terminal portion which is electrically connected to the first current collector,
• wherein the first active materials and the second active materials are partially provided so that the electric double-layer capacitor does not lose a light-transmitting property, and
• wherein the first active materials and the second active materials are embedded within the light-transmitting electrolyte layer;
• and
• a solar cell comprising:
• a first light-transmitting conductive film over a light-transmitting substrate;
• a photoelectric conversion layer in contact with the first light-transmitting conductive film;
• and
• a second light-transmitting conductive film in contact with the photoelectric conversion layer,
• wherein the electric double-layer capacitor and the solar cell are electrically connected to each other through the terminal portion, the first light-transmitting conductive film, and the second light-transmitting conductive film.
