Heliatek, a world leader in organic photovoltaic and a manufacturer of solar films based in Dresden, Germany, has put together a €80M round to finance the expansion of its HeliaFilm manufacturing capacity by one million square-metres per year. This round comprises €42M in equity, €20M in debt, and about €18M in subsidies.
The Heliatek GmbH (Dresden, Germany) has reached an important milestone in its pilot project in Singapore. The organic solar film HeliaFilm is being rigorously tested under the tropical weather conditions of Singapore to provide new urban-fit energy solutions for the ever growing cities of Asia.

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material. Solar cells made from compounds that have the crystal structure of the mineral perovskite have captured scientists’ imaginations.
