Title:
CAPACITOR-INTEGRATED SOLAR CELL HAVING ELECTRICITY STORAGE FUNCTION
Document Type and Number:
WIPO Patent Application WO/2012/144534
Kind Code:
A1
Abstract:
According to the present invention, a capacitor-integrated solar cell (100) having an electricity storage function, in which an electrode part (101) and a backside metal electrode (103) are connected in parallel with each other via a through hole (105), can be obtained.
A capacitor-integrated solar cell is configured to have a structure which comprises an electrode part (101), a light-receiving part (102) and a metal electrode part (107), in said structure the electrode part (101) and the metal electrode part (107) being connected via a through hole (105) that is filled with a conductive substance. The structure has a function of a capacitor by means of the metal electrode part and a capacitor electrode. The capacitor-integrated solar cell is characterized by having a function of a solar cell and a function of a capacitor that has an electricity storage function.
