Preparation parameter of dye plays important role in determining DSSC performance. This paper reports the influence of N719 dye dipping temperature on the optical properties and performance parameters of the DSSC utilizing TiO2 films prepared via microwave technique. The TiO2 coated N719 dye films were prepared at various temperatures, namely, 30, 50, 60, 70 and 80°C. It is found that the TiO2 film dipped into N719 dye solution at 50°C possesses the broadest optical absorption window and the highest dye loading. It is also found that the dye dipping temperature does not affect the leak current in the device. The short-circuit current density (JSC) and power conversion efficiency (η) are strongly influenced by the dipping temperature. The DSSC utilizing the sample prepared at 50°C demonstrated the highest JSC and η of 4.06 mA cm–2 and 1.36%, respectively due to highest dye loading and recombination resistance.
