This Catalyst article investigates the development of better, more energy-efficient solar cells. Every minute enough sunlight strikes the Earth to power our civilisation for a year, yet less than 1% of global energy generation is provided by solar energy. Solar cells convert sunshine directly to electricity, but to make them more attractive they have to perform at higher efficiencies and lower costs. Physicists around the world are working on a myriad of new technologies so that in the future we will be able to harness the Sun’s energy on a scale that matches its potential.
