We demonstrate for the first time that a fibre laser with a wavelength of 1070 nm and a pulse width of milliseconds can be applied to generate mesoporous nanocrystalline（nc） TiO thin films on ITO coated glass in ambient atmosphere,by complete vaporisation of organic binder and inter-connection of TiO nanoparticles,without thermally damaging the ITO layer and the glass *** dye sensitized solar cells with the laser-sintered TiO photoanode reached higher power conversion efficiency,compared with that for the *** impedance spectroscopy studies revealed that the laser sintering effectively increased dye adsorption,decreased charge transfer resistance and increased electron lifetime of the TiO thin *** use of the fibre laser with over 40%wall-plug efficiency offers an economically-feasible,industrial viable solution to the major challenge of rapid fabrication of large scale,mass production of mesoporous metal oxide thin film based solar energy systems,potentially for perovskite and monolithic tandem solar cells,in the future.
