The device was designed by scientists in Portugal to optimise light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode. December 20, 2021 Emiliano BelliniFrom pv magazine GlobalSolar redox flow cells (SRFCs) are devices that can store electricity by harvesting sunlight via a photoelectrochemical (PE) panel. These storage devices are attracting increasing interest from scientists and research institutes and have been developed so far only at research level.
Two of the biggest challenges these batteries have to overcome, along with other minor issues, are the fact that their performance is restricted by inefficient photoelectrochemical reactions…
