QUASI-SOLID-STATE DYE-SENSITIZED SOLAR CELLS BASED ON Z_nO PHOTOANODE

Abstract

ZnO photoanode in dye-sensitized solar cells (DSSCs) has been successfully prepared by the electro-hydrodynamic (EHD) technique. The sandwich solar cells exhibited a short-circuit photocurrent density of 7.0 mA cm⁻² and conversion efficiency of 1.65% with a quasi-solid-state electrolyte under simulated sun illumination (AM-1.5, 100 mW cm⁻²). The stability and the influencing factors, such as film thickness and light intensity, on solar cell performance were discussed.
