super thin and can be glued to almost anything: the new solar film from
Heliatek is intended to ensure nothing less than a revolution in the solar industry.
For twelve years, the Dresden company has been working on the so-called organic
Researched solar cell – now it stands
Technology shortly before its breakthrough, according to Martin Hermenau, the
Head of product development at Heliatek. "We will start with the 2020
Series production, "he says. The solar start-up with its 150 employees is currently looking for
Specialists, production runs in test mode.
The special: The
Solar film does not contain silicon, lead and other pollutants, that's what makes it
more environmentally friendly. Organic solar cells have another
Semiconductor, based on hydrocarbon compounds. That is why
Hermenau explains that the cell's ecological footprint is much smaller than that of conventional photovoltaic modules. In addition, there are material shortages, like for example
with rare earths, almost impossible.
Even Prime Minister Kretschmer praises it
In addition, the film
light and flexible. While normally solar modules appear as solid glass panels
Land on the roofs of houses and garages, the solar film can be used flexibly:

It actually works
currently the other way around. Germany has not exported for a long time
Significant solar cells, but
meanwhile it imports from China, Taiwan or South Korea. "Of the
There is not much left in Germany in the solar industry, "says Norbert Allnoch, head of the International Economic Forum for Renewable Energies (IWR), which is committed to expanding the
renewable energies. According to the Federal Ministry of Economics, there were still 156,700 people in 2011
employed in the solar industry, there were only 42,800 at the end of 2017. "Almost the entire industrial
Value added has been lost, "says Allnoch. Of the 350

Textbook example of wrong industrial policy, "says Volker Quaschning, professor for regenerative
Energy systems at HTW Berlin and co-organizer of Scientists-for-Future-Move. The government from the Union and the FDP cut this in 2011
Feed-in tariffs in the Renewable Energy Sources Act are so drastic that solar power production in Germany
became unattractive. The number of installations dropped by three quarters between 2012 and 2014. "The
But the world market is growing by 20 to 30 percent annually, "says Quaschning.
The manufacturers lacked the German market
German solar companies would have had to grow with them to remain competitive.
This is the only way to negotiate other prices, for example for silicon. "In
the moment the home market collapsed, the Germans had none
More chance to grow, "says Quaschnig, who estimates German manufacturers' share of the world market to be less than one percent

The acquisitions from China, South Korea and Taiwan primarily obtained valuable patents, the German one

Energy Systems (ISE) some patents "for the preservation of this future technology in

However, Asian companies used patents for their technological

All of the world's solar corporations now come from China, which compete primarily on price, "The cells and therefore the most valuable
