Abstract
This work is concerned with the comparative study of dye-sensitized solar cell (DSSC) utilizing selenium (Se) and palladium (Pd) cathode. The influence of concentration of selenium dioxide (SeO2) and palladium chloride (PdCl2) on the performance of the device has been investigated. The Se and Pd cathode have been prepared via dip coating-based multilayer deposition technique. The device using Se cathode with seven layers possesses the highest performance in term of short-circuit current density (Jsc). The photovoltaic measurement results show that the device utilizing Pd cathode demonstrates higher power conversion efficiency (?) compared with that of the device using Se cathode. The highest ? of the device with Se and Pd cathode are 0.071 and 0.169%, obtained at the 0.5 ?M SeO2 and 0.60 ?M PdCl2, respectively. The Pd cathode-based device prepared with 0.60 ?M PdCl2 owns the highest ? due to the lowest sheet resistance (Rs). These photovoltaic results imply single material has potential to be modified into binary or ternary cathode material in order to improve the performance of DSSC. � 2021 Indian Chemical Society
