Heliatek GmbH announced a record breaking 12%
cell efficiency for its organic solar cells, establishing a world
record. In cooperation with the University of Ulm and TU Dresden, the
solar cells were measured by the accredited testing facility
SGS. The measurement campaign at SGS also validated the superior low
light and high temperature performances of organic photovoltaics (OPV)
compared to traditional solar technologies.
The 12.0% record cell on a standard size of 1.1 cm² combines two patented absorber materials, which convert light of different wavelengths. Using two different absorber materials creates a stronger absorption of photons and improves energetic utilization through a higher photovoltage. Thanks to OPV's unique behavior at high temperatures and low light conditions, this 12% efficiency is comparable to about 14% to 15% efficiency for traditional solar technologies like crystalline silicon and thin film PV.
