Heliatek was spun-off in 2006 from the Technical
University of Dresden (IAPP) and the University of Ulm. The company is the global
leader in the development of organic photovoltaics (OPV) based on small
molecules and the manufacture of organic solar films. Investors in Heliatek
include leading industrial and financial companies such as BASF, Bosch, RWE,
and Wellington Partners. Research and development work, as well as the
installation of production technology, has been funded by the Free State of
Saxony, the BMBF (Federal Ministry for Education & Research), the BMWi
(Federal Ministry of Economics and Technology) and the European Union.
The key to Heliatek’s success is the family of small organic molecules –
oligomers – developed and synthesized at its own lab in Ulm, Germany.
Heliatek is the only solar company in the world that uses the deposition of
small organic molecules in a low temperature, roll-to-roll vacuum process. Its
solar tandem cells are made of nanometers-thin layers of high purity and
uniformity. This enables the company to literally engineer the cell
architecture to systematically improve efficiency and lifespan. This technology
is very similar to the well-established OLED technology (organic LEDs) except
that it operates in reverse, taking in light to create electricity. This
gives Heliatek access to readily available manufacturing machines, giving it a
fast track to reliable, volume production.
