    • There are disclosed a photoelectric conversion electrode having a large amount of a dye to be supported and an excellent dye replacement property and capability of improving a mechanical strength and a photoelectric conversion efficiency. In a photoelectric conversion electrode 11 according to the present invention, on a substrate 12 having a conductive surface 12a, an underlayer 13 containing a metal oxide and a porous metal oxide layer 14 including a metal oxide and a dye can be prepared by an electrolytic deposition process, and an electrolysis potential of the underlayer 13 is set to a potential or less of a flection point having a minimum potential among a plurality of flection points observed in a range of 0 to −1.5 V (vs. Ag/AgCl) in a current-potential profile during electrolytic deposition, whereby the underlayer is formed so that pointed crystal particles 13a of the metal oxide are piled up in a layer thickness direction.
    • 公开了一种具有大量待负载染料的光电转换电极,并且具有优异的染料替代性和提高机械强度和光电转换效率的能力。 在根据本发明的光电转换电极11中,在具有导电表面12a的基板12上,含有金属氧化物的底层13和包含金属氧化物的多孔金属氧化物层14和染料可以通过电解 沉积工艺,并且底层13的电解电位被设定为在0至-1.5V(相对于Ag / AgCl)的范围内观察到的多个反射点中具有最小电位的反射点的电位或更小的电位 电解沉积期间的电流 - 电位分布,由此形成底层,使得金属氧化物的尖晶体颗粒13a在层厚度方向上堆积。
