Uncovering quantum secret in photosynthesis

Scientists have been able to show for the first time at ambient conditions that the quantum mechanisms of energy transfer make phyotosynthesis more robust in the face of environmental influences. The quantum phenomenon responsible, known as coherence, is manifested in so-called photosynthetic antenna proteins that are responsible for absorption of sunlight and energy transport to the photochemical reaction centers of photosynthesis.

Innovative inspection method for photovoltaic systems

Scientists at the Institute of Photovoltaic at the University of Stuttgart have developed an innovative method, enabling damage to the photovoltaic modules to be revealed quickly, above all for the first time also independent of lighting conditions with the help of luminescence images.

Polymer-coated catalyst protects 'artificial leaf'

Researchers have modified so called superstrate solar cells with their highly efficient architecture in order to obtain hydrogen from water with the help of suitable catalysts. But the solar cell rapidly corrodes when placed in the aqueous electrolyte solution. Now, they have found a way to prevent corrosion by embedding the catalysts in an electrically conducting polymer and then mounting them onto the solar cell's two contact surfaces.

Generating wind energy from kites

The electricity from our sockets could soon come from a high-tech device flying in the sky. The innovative research project to generate wind energy with the aid of a kite won over the 'Venture Kick' jury; it is providing CHF 10,000 of support for the Empa spin-off 'TwingTec'.
