Berlin Science Week: Research Delivers – What is Slowing Down the Expansion of Solar Energy?
Thanks to new technologies from research, solar power does not cost more than coal-based electricity; but why is the expansion simply not getting off the ground?
Solar modules could also cover a considerable proportion of the energy requirements in cities - especially if the surfaces on the facades are also used in future. For this purpose, there are now a large number of aesthetically attractive facade solutions that also convert scattered light into electricity and are available in many colors and shapes. More and more solutions are emerging from research that enable even higher efficiencies and even lower module costs. The technologies are there and the kilowatt hour of solar power is no more expensive than coal-fired power. Yet the expansion is not getting off the ground. What is the reason for this?
Photovoltaics researchers from the Helmholtz-Zentrum Berlin (HZB) will meet with representatives from politics and industry in a panel discussion. They will discuss research successes, economic aspects, market strategies, political incentives, construction challenges and what is needed to ensure that more solar power soon finds its way into living rooms.
Panel:
- Samira Jama Aden (Architect at Helmholtz-Zentrum Berlin | PVcomB | BAIP)
- Prof. Steve Albrecht (Head of the young investigator group Perowskite Tandem Solar Cells, HZB)
- Prof. Claudia Kemfert (German Institute for Economic Research, Head of Department Energy, Transportation, Environment)
- N.N.
Host: Prof. Rutger Schlatmann (Director of the Competence Centre Photovoltaics Berlin, PVcomB / HZB)

- Detailed insights at BESSY II into the oxidation processes of copperBefore pure copper oxide builds up, complex superstructures such as ‘29’CuxO, are formed. The new results on the '29' CuxO superstructure have relevance for catalyst research and corrosion protection in the development of safe copper containers for nuclear waste repositories.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
