Heliatek achieves new world record for organic solar cells with certified 9.8 % cell efficiency

(PresseBox) (Dresden/Muenster, ) eCAPITAL portfolio company Heliatek GmbH, a global leader in high-end solar PV technology, has once again set a new world record for organic solar cells after Fraunhofer ISE CalLab certified a cell efficiency of 9.8 % for a 1.1 cm² tandem cell manufactured with a low temperature deposi-tion process. This new record makes the third time in a row that Heliatek has set a world record for efficiency in the field of organic photovoltaic and demonstrates its continuous technology leadership in organic solar.

One year ago, Heliatek GmbH set a world record for efficiency of 8.3 % for an active surface of 1.1 cm2. Thanks to its most recent developments, Heliatek has now been able to make a remarkable 1.5 % leap in cell efficiency, to 9.8 %. This new record was measured and certified by the independent Fraunhofer ISE CalLab (Freiburg, Germany) under standard test conditions.

Dr. Martin Pfeiffer, co-founder and CTO of Heliatek, explains: "Heliatek is the only solar company in the world focused on the deposition of small molecules with low temperature processes, a method that has already been widely adopted by the market for use with organic LEDs (OLEDs). Heliatek develops and synthesizes in-house the molecules responsible for capturing light in solar cells and converting this light into electricity. The new world record is a clear indication that Heliatek is headed in the right direction. Organic solar cells from Heliatek have now reached the level of efficiency of conventional solar cells made from amorphous silicon."

"Organic photovoltaic demonstrates vividly its right to be acknowledged as a valid alternative to known anorganic materials such as Si, CIGS, and CdTe. This record is not the end", adds Dr. Michael Luebbehusen, Managing Partner of eCAPITAL.

Heliatek has both its own chemistry research department as well as a physics research department. This unique combination creates efficient synergies, enabling simultaneous work on material quality and cell design. Heliatek was able to optimize the absorber layer system of the record-breaking cells through synthetizing the right materials. Furthermore, by improving the deposi-tion process, cell morphology was significantly improved, leading to an in-crease in power output and in fill factor.

The record-breaking cell construction will gradually be integrated into He-liatek's manufacturing process after the scheduled start of production in the second half of 2012. Heliatek's in-house measurements have shown that scal-ing up the record-breaking cells to a panel with a size factor >120 results in an efficiency over 9 % for the active module area.

Thibaud Le Séguillon, CEO of Heliatek, concludes: "I am delighted by this new result which confirms our technology leadership in this field. The next step on our way to 15 % will be a cell with over 10 % efficiency sometime next year. This latest record validates once again the decision taken at the outset by our investors and our team to commit ourselves to the production of organic solar based on small molecules using low temperature processes. Our flexible, thin and light panels open up new fields of applications that were so far impossible to address with conventional PV technologies. After our third investment round scheduled for 2012 - during which we plan to raise some €50 million in new capital from current and new investors - we plan to expand our production capacity with additional manufacturing lines. This will allow us to market our high-performance panels into new areas, such as windows and façades for BIPV. This technology has really the potential to revolutionize the solar indus-try."

For achieving this new record efficiency result, Heliatek acknowledges com-prehensive financial support of its R&D projects by the German Federal Minis-try of Education and Research (BMBF) under project numbers 13N9869 and 13N9716, as well as the European Regional Development Fund (ERDF) and Freistaat Sachsen under project number 71070.

Dr. Martin Pfeiffer (CTO of Heliatek GmbH), together with his fellow research-ers Prof. Karl Leo (Director of IAPP) and Dr. Jan Blochwitz-Nimoth (Novaled AG), has been nominated for the 2011 Deutschen Zukunftspreis for success-ful research in the field of organic electronics. On December 14th, German President Christian Wulff will announce the winner from the three teams of scientists in the running for the prize.

About Heliatek:

Heliatek, a global leader in high-end solar PV technology, was spun-off in 2006 from the Technical University of Dresden (IAPP) and the University of Ulm. The company's founding brought together internationally renowned ex-pertise in the fields of organic optoelectronics and organic oligomer synthesis. As the global technology leader in the field of organic photovoltaics (OPV) based on small molecules, Heliatek is currently making the transition from technology development to industrial manufacturing. Heliatek's goal is to mass-produce organic photovoltaic panels using the world's first roll-to-roll low temperature process for deposition of small molecules in 2012.

Heliatek maintains a total staff of some 70 employees and specialists at its facilities in Dresden and Ulm. Investors in Heliatek include leading industrial and financial companies such as BASF, Bosch, RWE, Wellington Partners, and eCAPITAL. Research and development work, as well as the installation of production technology, have been funded by the Free State of Saxony, the BMBF (Federal Ministry for Education & Research), the BMWi (Federal Minis-try of Economics and Technology), and the European Union.
