Dye-sensitized solar cells and organic thin-film solar cells are lightweight and have high process ability while maintaining low production costs and have been studied for the next generation of solar cells. ●Dye-Sensitized Solar Cells 　Grätzel and co-worker reported solar energy-to-electricity conversion efficiencies as high as 7-8% on dye- sensitized fractal-type TiO2 electrodes1). These solar cells, also known as the Grätzel cell, are composed of I) transparent electrode, II) TiO2, III) dyes, IV) electrolytes, V) counter electrode. Transparent Electrolyte Counter Electrode Electrode Dye 1) Dyes 　A large numbers of dyes (photosensitizer) have been synthesized to improve the efficiency of solar cells. Ruthenium complex dyes are most widely used for sensitizer. N719 dye (red dye) is a typical Ru-complex dye and a modification of the classical N-3 dye, to increase cell voltage. O O HO C C O N
