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.

    40 years of research with synchrotron light in Berlin
    Press release _ Berlin, 14 September: For decades, science in Berlin has been an important driver of innovation and progress. Creative, talented people from all over the world come together here and develop new ideas from which we all benefit as a society. Many discoveries – from fundamental insights to marketable products – are made by doing research with synchrotron light. Researchers have had access to this intense light in Berlin for 40 years. It inspires many scientific disciplines and is an advantage for Germany.
