Helmholtz Association promotes cooperation between HZB and Slovenia

The research focus is on the characterization of tandem solar cells made of perovskite and silicon.

A HZB team has successfully raised funds from the “Helmholtz European Partnering Program” of the Helmholtz Association to expand cooperation with partners of the University of Ljubljana, Slovenia.

Currently, most solar modules consist of silicon, a semiconductor that mainly uses the red parts of the solar spectrum to generate electricity. The combination of silicon with perovskite semiconductors therefore promises great opportunities for even higher efficiencies. Semiconductor materials from this material class convert the energy-rich, blue parts of the spectrum into electricity.

Now the HZB physicist Prof. Dr. Steve Albrecht has raised funds from the Helmholtz Association to investigate such tandem solar cells with partners from the University of Ljubljana, Slovenia. The TAPAS project is funded by the Helmholtz European Partnering programme for the next three years with 250,000 euros per year each. Following an evaluation, the funding period can be extended by two years. The Helmholtz European Partnering programme was set up to strengthen the European research area, in particular cooperation with countries in Southern, Central and Eastern Europe.

The name TAPAS stands for "Tandem Perovskite and Silicon solar cells - Advanced opto-electrical characterization, modeling and stability".  Together with opto-electrical modelling, highly efficient and stable next-generation tandem solar cells are to be developed for the energy system of the future.

The Working Group for Photovoltaics and Optoelectronics at the University of Ljubljana (LPVO, headed by Prof. Dr Marko Topič) and the Helmholtz-Zentrum Berlin have established a very successful cooperation in recent years, which will be further strengthened by this funding. The aim of the cooperation is to analyse the processes that affect the stability of the modules in the field.
