TANDEM SOLAR CELL

摘要

A solar cell is configured by: arranging two glass substrates, each of which is provided with a transparent conductive layer, so that the transparent conductive layers face each other; disposing a titanium dioxide layer on one glass substrate; disposing silicon dioxide particles on the other glass substrate; and filling the space between the two glass substrates with an electrolyte. The glass substrate on which light does not enter may alternatively be a metal plate. A sensitizing dye such as a ruthenium complex may be absorbed onto the titanium dioxide layer or the silicon dioxide layer. Since the titanium dioxide layer generates electric power by means of ultraviolet light incident thereon and the silicon dioxide layer generates electric power by means of visible light and infrared light incident thereon, the generation efficiency of the solar cell is increased.

1. A tandem solar cell comprising two glass substrates each having a transparent conductive layer formed thereon that are disposed to allow the transparent conductive layers to face each other;
a titanium dioxide photoelectromotive element that is disposed on one of aid glass substrates; a silicon dioxide photoelectromotive element that is disposed on the other of said glass substrates; and an electrolyte that is filled between the two glass substrates.
