Cooling down solar cells, naturally

Photovoltaics are more efficient when they operate at lower temperatures, which can be achieved in solar farms that space out arrays and use the wind to their advantage. A bright,…

Programmable laser beams save more than 30 percent energy

There is a new quality in laser material processing: With a liquid crystal modulator, the beam profile of a laser can be freely programmed with high temporal resolution, but also…

Protons fix a long-standing issue in silicon carbide electronics

Proton implantation prior to device fabrication could unlock the true potential of silicon carbide as a reliable semiconductor material. Silicon carbide (SiC) is a semiconductor material that outperforms pure silicon-based…

Rice lab’s catalyst could be key for hydrogen economy

Inexpensive catalyst uses energy from light to turn ammonia into hydrogen fuel. Rice University researchers have engineered a key light-activated nanomaterial for the hydrogen economy. Using only inexpensive raw materials,…

Successful measuring campaign for 50Hertz in the Baltic Sea

The Fraunhofer Institute for Wind Energy Systems IWES has successfully completed a boulder detection campaign off the coast of the island of Rügen in the German Baltic Sea on behalf…

Technique prints flexible circuits on curved surfaces

– from contact lenses to latex gloves. Researchers from North Carolina State University have demonstrated a new technique for directly printing electronic circuits onto curved and corrugated surfaces. The work…
