30.06.2021 Record Efficiency of 68.9% for GaAs Thin Film Photovoltaic Cell Under Laser Light
In addition to the classical applications for solar cells on roofs and open spaces, photovoltaic devices can also be used with laser light for efficient power transmission.
At the 48th IEEE Photovoltaic Specialists Conference, researchers from the Fraunhofer Institute for Solar Energy Systems ISE recently presented how they were able to achieve a record conversion efficiency of 68.9% with a photovoltaic cell under monochromatic laser light. For this, the research team used a very thin photovoltaic cell made of gallium arsenide and applied a highly reflective, conductive mirror on the backside.

New photonics research centers and production facilities for Germany and Canada
29 Apr 2021
Expansion for solar-focused Fraunhofer ISE; OPTICUM research center announced for Hannover; and Coractive plans new plant in Quebec.
Now open: the ISE Center for High Efficiency Solar Cells, in Freiburg.To maintain and strengthen its global leadership position in solar energy research, Fraunhofer ISE has been expanded with a new laboratory building, which opened this week in Freiburg, Germany. It was funded in equal parts by the German Federal Ministry of Education and Research BMBF and the State of Baden-Württemberg.
In his welcoming address on the occasion of the inauguration of the new Fraunhofer ISE laboratory building, Minister President Winfried Kretschmann commented, âIn Baden-Württemberg, we have set ourselves numerous goals for climate policy, and solar energy plays a central role. With Fraunhofer ISE, we have had one of the most important solar research institutes w
