Charge Transport in 1-D Nanostructured CdS Dye Sensitized Solar Cell

Abstract

Charge transport in eosin yellow sensitized CdS 1-D nanostructures is studied. Direct conduction pathway for electron transport in nanowires enhances V oc in CdS nanowires compared to nanorods and nanoparticles. J - V characterization of nanowires results in improved efficiency of 0.184% due to fewer interparticle connections. Increase in J sc is observed by coating CdS 1-D nanostructures on TiO 2 substrate which reduces rate of recombination and photocorrosive nature of CdS photoanodes. Enhancement in efficiency up to 0.501% is achieved for CdS 1-D nanostructures DSSCs on TiO 2 substrate.
