Abstract

Abstract A preparation technique of TiO 2 screen‐printing pastes from commercially‐available powders has been disclosed in order to fabricate the nanocrystalline layers without cracking and peeling‐off over 17 µm thickness for the photoactive electrodes of the dye‐sensitised solar cells. A conversion efficiency of 8·7% was obtained by using a single‐layer of a semi‐transparent‐TiO 2 film. A conversion efficiency of 9·2% was obtained by using double‐layers composed of transparent and light‐scattering TiO 2 films for a photon‐trapping system. Copyright © 2007 John Wiley & Sons, Ltd.
