“…Since the first demonstration of dye-sensitized solar cells by Grätzel and co-workers in 1991, there have been many efforts to improve the solar-to-electric power-conversion efficiency (PCE) of DSSCs. As a result, the PCE of DSSCs has reached 12%, through the development of high efficient photoanodes [5][6][7], dyes [8] and electrolytes [9].…”

Mesoporous TiO 2 granules were prepared by spray pyrolysis using nano-sized titania particles which were synthesized by a hydrothermal method, and they were evaluated as the photoanode of dye-sensitized solar cells. To enhance the cell efficiency, nanoparticles within granules were chemically interconnected by adding titanium ethoxide (TEOT) to colloidal spray solution. The resulting titania particles had anatase phase without forming rutile. TiO 2 granules obtained showed about 400 nm in size, the specific surface area of 74-77 m 2 /g, and average pore size of 13-17 nm. The chemical modification of TiO 2 granules by adding TEOT initially to the colloidal spray solution was proved to be an effective way in terms of increasing both the light scattering within photoanode and the lifetimes of photo-excited electrons. Consequently, the light-harvesting efficiency of TEOT-modified granules (η=6.72%) was enhanced about 14% higher than primitive nanoparticles.
