Title: Rapid sintering of TiO{sub 2} photoelectrodes using intense pulsed white light for flexible dye-sensitized solar cells

Intense pulsed white light (IPWL) sintering was carried out at room temperature, which is suitable dye-sensitized solar cells (DSSCs) fabrication process on plastic substrates for the mass production. Five seconds irradiation of IPWL on TiO{sub 2} electrode significantly improves the photocurrent density and power conversion efficiency of DSSCs by more than 110% and 115%, respectively, compared to the DSSCs without IPWL treatment. These improvements were mainly attributed to the enhanced interconnection between the TiO{sub 2} nanoparticles induced by IPWL illumination, which is confirmed by the impedance spectra analysis.
