University of California Davis researchers are asking, “What if solar cells worked at night?” They are not joking. In fact, their specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime, according […]

A new approach developed at MIT uses sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell that could generate power from sunlight efficiently and on demand.  The MIT researchers expect the technique could also make it easier to store the energy for later use. The new […]
