DYE-SENSITIZED SOLAR CELLS USING WIDE WAVELENGTH RANGE ABSORPTION NANOSTRUCTURE AND METHOD FOR PREPARING THE SAME

摘要

A dye-sensitized solar cell using wide wavelength range absorption nanostructure and a method for preparing the same are provided to improve the photocurrent density by forming a nano-particle layer which has the optical absorption wavelength. A photo electrode(100) comprises a metal oxide nano-particle layer in which dye is absorbed on the transparent conductive substrate. A counter electrode(200) comprises a platinum layer(220) and a metal oxide nano-particle layer in which the dye is absorbed. The electrolyte(300) fills the interval between the photo electrode and the counter electrode. The photo electrode and the metal oxide nano-particle layer of the counter electrode are arranged to face each other. The counter electrode comprises an insulating layer(240) between the metal oxide nano-particle layer and the platinum layer.
