چکیده انگلیسی
This paper reports the effect of surface topography of titanium dioxide films on short-circuit current density of photoelectrochemical solar cell of ITO/TiO2/PVC-LiCLO4/graphite. The films were deposited onto ITO-covered glass substrate by screen-printing technique. The films were tempered at 300 °C, 350 °C, 400 °C, 450 °C and 500 °C for 30 min to burn out the organic parts and to achieve the films with porous structure. The surface roughness of the films were studied using scanning electron microscope (SEM). Current-voltage relationship of the devices were characterized in dark at room temperature and under illumination of 100 mW cmâ2 light from tungsten halogen lamp at 50 °C. The device utilising the TiO2 film annealed at 400 °C produces the highest short-circuit current density and open-circuit voltage as it posses the smoothest surface topography with the electrolyte. The short-circuit current density and open-circuit voltage of the devices increase with the decreasing grain size of the TiO2 films. The short-circuit current density and open-circuit voltage are 0.6 μA/cm2 and 109 mV respectively.
