Provided is a dye-sensitized solar cell in which the energy conversion efficiency is increased by adsorbing two different kinds of dyes to the surface of titanium oxide that constitutes a semiconductor electrode. In a dye-sensitized solar cell including a conductive support, a porous semiconductor layer having sensitizing dyes adsorbed onto this conductive support, a carrier transport layer and a counter electrode, the energy conversion efficiency is increased by adsorbing a mixture of a ruthenium complex, and an organic dye having a different molecular size and exhibiting a high open circuit voltage as a photoelectric conversion characteristic obtainable by the dye alone, onto the porous semiconductor layer.
提供的是一种染料敏化太阳能电池,其中通过将两种不同的染料吸附到构成半导体电极的二氧化钛表面来提高能量转换效率。在包括导电支撑、具有敏化染料吸附到该导电支撑上的多孔半导体层、载流子传输层和对电极的染料敏化太阳能电池中,通过将一种钌配合物和一种具有不同分子大小且表现出高开路电压作为仅染料本身可获得的光电转换特性的有机染料的混合物吸附到多孔半导体层上,提高了能量转换效率。
