Abstract
Today's solar cells absorb only visible light, wasting the infrared that makes up half of the Sun's output that reaches Earth. But a new material developed in Spain can absorb infrared too, and should make it possible to hike the power solar cells can produce, say researchers. Conventional solar cells are based on a semiconductor such as silicon. But their inability to soak up infrared gives them a theoretical absorption limit of just over 40% of solar energy. In practice, they only absorb about 30%. The new material, though, can harness both visible and infrared photons, so it has a theoretical maximum efficiency of 63%, it creators say, and should give significantly better real-world performance
