After the 'sunrush': what comes next for solar power?

The fall in costs that has driven solar’s rapid growth is slowing - but scientists are exploring the next generation of materials that can harness more energy from the sunSome people call it the “sunrush”: a 25-year period in which solar power has grown exponentially, transforming the technology from rarefied oddity to the world’s fastest-growing energy source.This surge, which saw 100MW of capacity in 1992 rocket to more than 300GW in 2016, has been largely driven by fal
