Abstract

Mass transport of the [Co(bpy)3]II/IIIredox electrolyte is found to strongly depend on porosity and pore size of mesoporous TiO2 films. Photocurrent density is improved by nearly two times with increasing the porosity from 0.52 to 0.59 despite 23% decreased dye loading. Optimized nanostructure sensitized with MK-2 dye shows efficiency of 5.5% at 1 sun.
