New Kind of ‘Solar’ Cell Shows We Can Generate Electricity Even at Night

Conventional solar technology soaks up rays of incoming sunlight to bump out a voltage. Strange as it seems, some materials are capable of running in reverse, producing power as they radiate heat back into the cold night sky. A team of engineers in Australia has now demonstrated the theory in action, using the kind of … Read more
