MANHASSET, NY -- Heliatek GmbH has achieved an organic solar cell efficiency of 9.8 percent for a 1.1 cm² tandem cell manufactured with a low-temperature deposition process.
The purported world record certified by independent Fraunhofer ISE CalLab makes the third time in a row that Heliatek has set a world record for efficiency in the field of organic photovoltaic, according to the company.
Earlier, Heliatek achieved 8.3 percent efficiency for an active surface of 1.1 cm².
“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). Organic solar cells from Heliatek have now reached the level of efficiency of conventional solar cells made from amorphous silicon,” said Martin Pfeiffer, co-founder and CTO of Heliatek, in a statement.
The new cell construction will gradually be integrated into Heliatek’s manufacturing process in the second half of 2012. Heliatek’s in-house measurements have shown that scaling up the cells to a panel with a size factor >120 results in an efficiency over 9 percent for the active module area.
“The next step will be a cell with over 10 percent efficiency sometime next year," said Thibaud Le Séguillon, CEO of Heliatek.
Heliatek was spun off in 2006 from the Technical University of Dresden (IAPP) and the University of Ulm.
