Effect of aqueous media on photoelectrochemical water splitting performance of �-Fe2O3/LaFeO3:Cr tandem cell
A tandem cell that consists of an n-type (�-Fe2O3/hematite) photoanode and a p-type (LFO:Cr/chromium-doped lanthanum iron oxide) photocathode for solar water splitting has been demonstrated and studied for its photoelectrochemically. Under two-electrode system configurations, the PEC performance of...
