A really cool piece of science and nano-engineering, I can see why they patented it before publishing in Nature Communications. This technology would be ideal for low power stationary systems and will most likely replace any current solar-battery systems currently deployed. Of course, this is still at an early stage, but if they can maintain reversibility and extend device lifetime, I think they are onto a winner. Definitely one to watch!
“The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy,” Wu said. “We’ve integrated both functions into one device. Any time you can do that, you reduce cost.”
