A Theoretical Study on Overpotential and Photocurrent of a Photo Fuel Cell

Abstract

A theoretical study on a TiO₂-based photo fuel cell (PFC) is presented. The different types of overpotentials which the PFC could face with were investigated in this research. In addition, the effect of temperature on the overpotentials was studied. Moreover, it was shown that electron transfer overpotential increased versus the Schottky barrier height (SBH) at higher current densities. Also, higher flux density of photons and higher quantum efficiencies resulted in more photocurrent density. This paper provides a good view for the prospective researches at the areas of PFC modeling.
