What are solar cells, and how do they work? Find out more about solar power - and learn how this renewable resource harnesses the power of the sun into usable energy.
The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.
