| In world first, researchers convert sunlight to electricity with over 40 percent efficiency Posted: 07 Dec 2014 06:16 AM PST Australia's solar researchers have converted over 40 percent of the sunlight hitting a solar system into electricity, the highest efficiency ever reported. A key part of the prototype's design is the use of a custom optical bandpass filter to capture sunlight that is normally wasted by commercial solar cells on towers and convert it to electricity at a higher efficiency than the solar cells themselves ever could. |
