By mounting a water distillation system on the back of a solar cell, engineers have constructed a device that doubles as an energy generator and water purifier.<\/p>\n

While the solar cell harvests sunlight for electricity, heat from the solar panel drives evaporation in the water distiller below. That vapor wafts through a porous polystyrene membrane that filters out salt and other contaminants, allowing clean water to condense on the other side. \u201cIt doesnt affect the electricity production by the [solar cell]. And at the same time, it gives you bonus freshwater,\u201d says study coauthor Peng Wang, an engineer at King Abdullah University of Science and Technology in Thuwal, Saudi Arabia.<\/p>\n

Solar farms that install these two-for-one machines<\/a> could help meet the increasing global demand for freshwater while cranking out electricity, researchers report online July 9 in Nature Communications<\/em>.<\/p>\n

Using this kind of technology to tackle two big challenges at once \u201cis a great idea,\u201d says Jun Zhou, a materials scientist at Huazhong University of Science and Technology in Wuhan, China not involved in the work.<\/p>\n

In lab experiments under a lamp whose illumination mimics the sun, a prototype device converted about 11 percent of incoming light into electricity. Thats comparable to commercial solar cells<\/a>, which usually transform some 10 to 20 percent of the sunlight they soak up into usable energy (SN: 8\/5\/17, p. 22<\/em>). The researchers tested how well their prototype purified water by feeding saltwater and dirty water laced with heavy metals into the distiller. Based on those experiments, a device about a meter across is esRead More \u2013 Source<\/strong><\/a>
