Roland Piquepaille’s Technology Trends has a good writeup on a new photovoltaic cell that doesn’t need a battery for power storage. “Solar cells can convert solar energy to electricity, but that’s about all they can do. You need batteries to store, and then release, this electricity. But this extra-step might soon no longer be necessary. Japanese scientists have developed a new type of solar cell which integrates an electricity storage device.” [ more ]
