How a ‘solar battery’ could bring electricity to rural areas

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.
The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists tr
