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)

- Only at BESSY II worldwide: IR nanoscopy at very long THz wavelengthsThe team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.
- Blind spot for the arrangement of atomsArtificial intelligence is increasingly being used to predict the properties of new materials. A research team from Jena and the United States now shows in a study published in the journal Nature Computational Science that when language models are used for this purpose, they reliably identify which types of atoms a material contains. However, they make insufficient use of information about how those atoms are arranged in space. Neither larger models nor additional training data resolve this weakness. For material properties that depend strongly on structure, AI models specifically designed to process spatial relationships are therefore the more reliable choice. (DOI: 10.1038/s43588-026-01045-2)
- Patterns of polar vortices in lead-free superlattices on siliconA team at HZB has, for the first time, reported polar vortices in (BaTiO3/SrTiO3)10 superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open up new options for incorporating complex ferroelectric states into silicon-based technologies.
