Photovoltaics

A particular focus is on the further development of modern technologies such as silicon photovoltaics, research into tandem solar cells and innovative perovskite solar cells. Photovoltaic systems are also considered holistically - from the individual cell to integration into energy-efficient overall solutions.

Building-integrated photovoltaics (BIPV) is also an important topic of our research. Here we combine architectural design with energy-efficient energy generation to create aesthetically pleasing and functionally efficient solutions for the energy transition in the building sector.
