Abstract

A dye-sensitized solar cell, comprising: a light-transmission substrate; a plurality of auxiliary electrodes, formed on the light-transmission substrate; an oxide semiconductor layer which is formed on the light-transmission substrate so as to cover the plurality of auxiliary electrodes directly; and dyes, adhered to the oxide semiconductor layer. Each of electrons, excited at the dyes, is transferred to a nearest auxiliary electrode over a distance “C”, which is smaller than a thickness “B” of the oxide semiconductor layer.

Claims (39)
