A solar-energy storage cell that works at night

A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it’s dark. The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source. Those systems are hindered by not being able to use that solar energy at night or when cloudy conditions exist. The UT Arlington team developed an all-vanadium photo-electrochemical flow cell that allows for efficient and large-scale solar energy storage even at nighttime. The team is now working on a larger prototype.” - Link
