The study also investigates the influence of morphology at the semiconductor electrode/electrolyte interface along with quantitative determination of the morphological parameters of the rough electrode surface affecting the photoelectrochemical response using power spectral density analysis. Studies revealed that the Fe₂O₃ sample (E_100cy) prepared with 100 cycles of electrochemical deposition showed the highest photocurrent density of 2.RSC advancesEffect of morphology and impact of the electrode/electrolyte interface on the PEC response of Fe₂O₃ based systems - comparison of two preparation techniques.PMC9057922103/241/2015-NTIndo-US project vide no.
