The investigation on different light harvesting layers and their sufficient effect on the photovoltaic characteristics in dye sensitized solar cell

Titanium dioxide-based nanofibers (TiO2 nanofiber) were prepared by an electrospinning technique. The electrospun composite fibers were synthesized at different concentrations of titanium isopropoxide (25.35, 50.69, 76.05 wt%) and calcinated at different temperatures (450 oC, 650 oC and 850 oC) for 2 h. The diameters of nanofibers decreased by increas...

TiO2-Anatase Nanowire Dispersed Composite Electrode for Dye-Sensitized Solar Cells

TiO2 anatase nanowires have been prepared by a hydrothermal process followed by post-heat treatment in air. TiO2 nanoparticle/TiO2 nanowire composite electrodes were prepared for dye-sensitized solar cells (DSC) in order to improve light-to-electricity conversion efficiency. The TiO2 NP/TiO2 NW composite cells showed higher DSC performance than ordinary nanoparticle cells and fully nanowire cel...
