Spanish and Finnish scientists have developed a solar vanadium redox flow battery paired with commercially available CIGS solar panels. The open-circuit voltage values were high enough to achieve unbiased photocharge, they said.Scientists from Spain's IREC Catalonia Institute for Energy Research and Finland's Aalto University have combined vanadium redox flow batteries (VRFBs) with mini solar modules based on copper, indium, gallium, and selenium (CIGS) tech within a single device, in a bid to take advantage of their high energy density. The researchers said that the high voltage of the VRFBs ...Den vollständigen Artikel lesen ...
