Dye-sensitized solar cells using zinc sulphide-coated titanium dioxide films as photoanode: Effect of immersion temperature on its performance

Abstract

This work is concerned with the utilization of ZnS-coated TiO2 films as photoanode in a dye-sensitized solar cell (DSSC). The effect of immersion temperature of TiO2 films in ZnS solution on the optical properties and photovoltaic parameters has been studied. The sample prepared at 50°C of immersion temperature possesess the highest optical reflection which is around 42% in the visible region. The DSSC utilizing the sample prepared at 50°C performed the highest η of 0.28%. This is due to this device owns the the highest optical reflection that means that it has the highest light scaterring.
