A record-breaking solar panel that can convert more than a quarter of the sunlight it receives into electricity has been developed by researchers in Japan. The silicon solar cell is so efficient that it turns 26.3 per cent of the energy from the sun into renewable power. In contrast, nature’s ‘solar panels’ – leaves – have a “photosynthetic efficiency” of between three and six per cent. The scientists behind the new panel also said they believed they had found a way to create a one with the maximum level of efficiency considered to be theoretically possible – 29.1 per cent.
