Dye-Sensitized Nanocrystalline ZnO Solar Cells Based on Ruthenium(II) Phendione Complexes
Figure 7
Photocurrent action spectrum obtained with the nanocrystalline ZnO solar cell sensitized by (Ru(phen)2(phendione))2+ (1) with the electrolyte of 0.6 M DMPImI, 0.1 M LiI, 0.05 M I2, and 0.5 M TBP in methoxyacetonitrile (solid line) and Ru(deeb)/TiO2 in 0.5 M LiClO4/0.05 M I2 electrolyte. The TiO2 surfaces were pretreated with pH 2 (circles) aqueous solution [37]. Ru-(deeb)2(py)2/TiO2 (squares) and Ru(bpy)2(ina)2/TiO2 (triangles) are regenerative solar cell in 0.5 M LiI/0.05 M I2 acetonitrile electrolyte [38]. IPCE is represented as a function of wavelength.
