This is a world record. Clever cleaning of solar modules Dust accumulating on solar panels is a big problem. But washing the panels consumes large amounts of water. MIT engineers have now developed a waterless cleaning method. Paper-thin solar cell turns any surface into a power source MIT engineers have developed ultra-light fabric solar cells that can quickly and easily turn any surface into a power source. Solar cells from the printer The solar cells from the inkjet printer are ultra-thin and flexible - and should also work inside buildings. Researchers create record-breaking flexible solar cell Never before have flexible solar cells been so efficient: A team from the Swiss Federal Laboratories for Materials Science and Technology (Empa) has created a flexible thin-film solar cell with a record-breaking efficiency of 20.8 percent. ETH researchers produce fuel from sunlight and air Researchers at the Swiss Federal Institute of Technology in Zurich (ETH) have achieved a world première: They have developed a technology that produces carbon-neutral fuels using only sunlight and air. The solar refinery is already operating under real-life conditions. Cheap raw material for smartphones and solar cells Whether for smartphone screens or solar cells: Precious metals such as iridium or ruthenium are in high demand. Researchers from Basel have developed a cheaper and less toxic alternative. New water filter removes pathogens A research team from the Swiss Federal Institute of Technology Lausanne (EPFL) has presented a prototype of a low-cost filter that efficiently decontaminates water using only sunlight. The device is intended to provide clean drinking water for people in regions with little electricity. Sun soon to be the most important source of energy The sun is likely to become the world's most important source of energy before 2050, according to British scientists. This is the result of an analysis of technological and economic data by the University of Exeter and University College London. Sahara sun from the laboratory ETH Zurich has put an artificial sun into operation. In the room of a new laboratory, the sun shines at the push of a button, just as it does at midday in the Sahara or in January in Berlin.
