Charge recombination at the conductor substrate/electrolyte interface has been prevented by using efficient blocking layers of TiO2compact films in dye-sensitized solar cell photoanodes. Compact blocking layers have been deposited before the mesoporous TiO2film by the layer-by-layer technique using titania nanoparticles as cations and sodium sulfonated polystyrene, PSS, as a polyanion. The TiO2/PSS blocking layer in a DSC prevents the physical contact of FTO and the electrolyte and leads to a 28% increase in the cell's overall conversion efficiency, from 5.7% to 7.3%. © 2009 Elsevier B.V.
