Heliatek claims world record for organic solar cells with certified 9.8 percent cell efficiency
One year ago, Heliatek set a world record for efficiency of 8.3 % for an active surface of 1.1 cm ² . Heliatek has now been able to make a 1.5 % leap in cell efficiency, to 9.8 %.
Dr. Martin Pfeiffer, co-founder and CTO of Heliatek, explained: “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.”
Heliatek optimized the absorber layer system of the record-breaking cells through synthetizing the right materials. By improving the deposition process, cell morphology was also 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.
Thibaud Le Seguillon, CEO of Heliatek, said: “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.”
