Heliatek achieves new world record for organic solar cells with certified 9.8 % cell efficiency
One year ago, Heliatek GmbH set a world record for efficiency of 8.3 % for an active surface of 1.1 cm².

  • Heliatek GmbH, 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 deposition process.
  • Start of industrial production is scheduled for the second half of 2012.

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.
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 deposition process, cell morphology was significantly improved, leading to an increase in power output and in fill factor.
The record-breaking cell construction will gradually be integrated into Heliatek’s manufacturing process after the scheduled start of production in the second half of 2012.

Heliatek’s in-house measurements have shown that scaling up the record-breaking cells to a panel with a size factor >120 results in an efficiency over 9 % for the active module area.
