Azobenzene Stores Solar Energy
https://hackaday.com/2019/11/12/azobenzene-stores-solar-energy/
Probably the most efficient way to convert solar energy into electricity is the old fashioned way, heating water into steam and turning a turbine. This remains a messy affair though and you don’t really want a steam boiler on your roof, so solar cells are popular. However, there’s some new …read more (https://hackaday.com/2019/11/12/azobenzene-stores-solar-energy/)
