Read moreIn the race for higher power yields, the Zentrum f�r Sonnenenergie- und Wasserstoff-Forschung Baden-W�rttemberg (Centre for Solar Energy and Hydrogen Research, ZSW) has set a new world record. The Stuttgart researchers have improved the efficiency of CIGS thin-film solar cells to 20.8%. This figure is a record for converting sunlight into electrical energy and, for the first time, it exceeds the efficiency of market-dominating multicrystalline silicon solar cells.

Read moreVast energy sources are slumbering below big cities. Sustainable energies for heating in winter and cooling in summer may be extracted from heated groundwater aquifers. Researchers from KIT and ETH Zurich developed an analytical heat flux model and found that increasing heat in the underground is mainly caused by an increase in surface temperatures and heat release from buildings.

Read moreBillions of euros are spent treating trillions of litres of wastewater every year, consuming substantial amounts of energy. However, this wastewater could act as a renewable resource, saving significant quantities of energy and money, as it contains organic pollutants which can be used to produce electricity, hydrogen and high-value chemicals, such as caustic soda.

Read moreConverting heat directly into power could be a major source of renewable energy. A novel approach to study this so called thermoelectricity may help to design new materials that are highly efficient. In an experiment with cold atoms trapped by lasers at ETH Zurich an international group of physicists precisely simulates the behavior of thermoelectric materials.
