The use of laser transfer techniques to produce porous nc-TiO 2 films required for dye-sensitized solar cells was presented. Pulsed laser deposition and laser direct-write techniques were applied to deposit the dense and porous nanocrystalline TiO 2 layers. A pulsed ultraviolet (UV) laser was used to forward transfer a suspension of TiO 2 nanopowder onto a F-doped SnO 2 coated glass substrate. It was found that the dye solar cells fabricated with the laser processed TiO 2 layers on the glass had a power conversion efficiency of 3∼4.3% under an illumination of 10mW/cm.
