摘要:
The present invention relates to a solar power generation device which includes an electric double-layer capacitor and a solar cell. The electric double-layer capacitor includes a pair of current collectors formed using a light-transmitting conductive material; active materials which are dispersed on the pair of current collectors; a light-transmitting electrolyte layer which is provided between the pair of current collectors; and a terminal portion which is electrically connected to the current collector. The solar cell includes, over a light-transmitting substrate, a first light-transmitting conductive film; a photoelectric conversion layer which is provided in contact with the first light-transmitting conductive film; and a second light-transmitting conductive film which is provided in contact with the photoelectric conversion layer. 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.
摘要:
Highly-pure graphite oxide, graphene oxide, or graphene is mass-produced. Graphite is oxidized by an oxidizer, so that a graphite oxide solution is obtained, and electrodialysis is performed on the graphite oxide solution to remove aqueous ions, whereby the purity of graphite oxide is increased. Graphene oxide manufactured using the graphite oxide is mixed with powder, and the mixture is reduced, whereby graphene exhibiting conductive properties is yielded and the powder can be bonded. Such graphene can be used instead of a conduction auxiliary agent or a binder of a variety of batteries.
