| Abstract: | The electro-hydrodynamic (EHD) technique has been successfully applied for manufacturing ZnO photoanode in dye sensitized solar cells (DSSCs). Porous structure of ZnO film after calcinations was beneficial to the absorption of dye and infiltration of electrolyte. By using ionic liquid as an electrolyte, a high short-circuit photocurrent density of 12.1 mA/cm2 was attained and the overall photo-to-electric energy conversion efficiency (η) was 3.4% under an AM-1.5 illumination at 100 mW/cm2. At the same time, the influence factors on the solar cell performance, such as the concentrations of polyvinyl alcohol (PVA) during EHD process and light intensity were discussed.
