    Efficient production of monocrystalline semiconductors

    A Freiberg-based semiconductor manufacturer has now developed a new process that enables up to nine crystals to be grown simultaneously in parallel. This reduces the specific energy consumption for the production by two thirds. The new technological principle can be applied to growing other semiconductor substrates.  more...
     

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Batteries in the low-voltage grid for more PV energy

    In areas where already a large number of photovoltaic systems are installed, impermissibly high voltages can occur in the power grid on sunny days. It therefore needs to be clarified how the energy generated can be optimally used both technically and economically. One idea is that new charging strategies for batteries can effectively relieve the grid by optimally integrating the energy storage systems.  more...
     

    Identifying risks and minimising them through regulations

    How safe and reliable are photovoltaic installations with lithium-ion storage systems? In order to find out, scientists are investigating different plant systems. The intention is to identify possible weak points – such as during transport and installation – so that they can be taken into account in future standardisation work.  more...
     

    Quadruple solar cell achieves record-breaking efficiency

    Researchers have developed a quadruple solar cell that converts 46 per cent of sunlight into electricity. The high-performance cells achieve this record-breaking efficiency in connection with optics that concentrate the light 508 times. If these cells were built in concentrator modules, energy would be produced even more economically in regions with high levels of sun.  more...

    Heating system keeps rotor blades ice-free

    In cold climate zones, the wind is particularly strong meaning best conditions for a wind turbine. However, in the cold temperatures there is the danger of ice that can freeze onto rotor blades. This can lead to imbalances, impairment of the rotor blade’s aerodynamics and a drop in the efficiency of the turbine. The so-called carbon-nanotube coating offers a solution.  more...
     

    Combining compost and biogas

    A new method improves the energy balance and processing capacity of composting plants. With the usual composting process, considerable energy is consumed to provide the required mechanical ventilation. In the new method, the liquid organic components of the organic waste are separated in advance and are used for producing biogas. This enables energy to be generated in the plants. For the project, a new biofilm digester has been designed which provides cost advantages relative to other digestion processes.  more...
     

    Fast-track testing of nacelles

    In Bremerhaven, a test rig is being developed that can test complete wind turbine nacelles in the multi-megawatt class. Unprecedented: a load transmission system mechanically simulates the wind loads occurring in the field. The researchers are investigating the electrical components using a simulated electricity grid. Laboratory tests are also providing information on how wind turbine concepts can be improved. With these properties, the test rig has the world’s most powerful grid simulation system.  more...

    Low-cost collector integration in buildings

    To promote the spread of solar thermal energy further, the cost of system components must come down. Under the stewardship of the Fraunhofer Institute for Solar Energy Systems ISE, scientists have developed collectors with absorbers and coverings produced from low-cost plastic. Over 30 terraced houses in the Mortensrud neighbourhood near Oslo in Norway have been fitted with the new technology and showcased recently to the public.  more...

    New coating protects masts from corrosion

    Submerged sections of offshore plants provide the ideal habitat for colonisation by mussels and microorganisms. This can lead to biologically-induced corrosion and premature wear. To inhibit this, new coatings and surface structures are being developed by 14 partners from science and industry in the Foulprotect project. These are intended to protect plant foundations against "biofouling".  more...
