Vision: To make photovoltaics the most important energy technology of the 21st century

To successfully meet the challenges of climate change, renewable energies must be implemented globally at a massive scale. Alongside wind energy, photovoltaics will play a dominant role.

Recent years have seen exponential growth in the production of solar cells at the gigawatt scale. Nevertheless, we are at the very beginning of a global development; terawatts of energy are required. This successful trend has been driven by sharply falling prices for photovoltaic energy supply. And in addition to falling production costs, the energy conversion efficiency of solar cells has played a decisive role.

The research of the laboratory of “Photovoltaic Energy Conversion” is focused on this goal. On the one hand, it works to improve existing silicon technology, on the other, it develops new solar-cell structures such as perovskite- and tandem solar cells.

Research

Research focus: increasing the efficiency of solar cells, understanding loss mechanisms and developing new solar cell concepts.
