Harvesting energy from the temperature difference between photovoltaic cell, surrounding air leads to a viable, renewable source of electricity at night

12-Apr-2022

About 750 million people in the world do not have access to electricity at night. Solar cells provide power during the day, but saving energy for later use requires substantial battery storage. In Applied Physics Letters, by AIP Publishing, researchers from Stanford University constructed a ...
