Systems integrated in rotor blades generate air currents. The aerodynamics of the wind turbine improve, the energy yield increases.

No ice and no erosion at the blade edge of wind turbines. New thermoplastic hybrid material with integrated heating foil protects the leading edge.

Multi-junction solar cells are suitable for concentrating photovoltaics in sunny countries. The efficiency of the module reaches 41 percent.

Modules for concentrating photovoltaics are to be built directly on site in sunny countries to save transport and production costs.

Special measurement methods monitor the condition of the power electronics and determine the remaining lifetime of the individual components.

No lime on bearings and seals of submersible pumps that pump hot and calcareous thermal water at a depth of several hundred metres.

LaserJetDrilling is the name of a new process in which a laser beam that is guided within a water jet weakens hard rock before it is actually drilled.

Test benches offer reproducible conditions compared to testing new wind turbines in the open field. But is this data enough for certification alone?

Bifacial silicon solar cells achieve an efficiency of 21.6 per cent. New ultra-thin wires cut more wafers from a silicon crystal.
