A device that can produce electricity from sunlight while simultaneously purifying water has been produced by researchers, an invention they say could solve two problems in one stroke.
The researchers say the device is not only a source of green energy but also offers an alternative to current technologies for purifying water. These, they add, often consume large amounts of electricity and require infrastructure beyond the reach of many communities that lack basic access to safe drinking water – a situation thought to affect more than 780 million people worldwide.
