Abstract

The CdS quantum dots were deposited on nanoporous TiO₂ by chemical bath deposition technique to absorb the visible light in the longer wavelength region and are used as photo electrode in the dye sensitized solar cells (DSSC). The CdS quantum dots deposited on nanoporous TiO₂ at 1 min deposition time showed improved short circuit current density (J_sc) and open circuit voltage (V_oc) than films deposited at higher dipping times. The increase in the CdS dipping time reduces the amount of dye adsorbed on nanoporous TiO₂ which limits the redox reactions in the electrolyte.
