Heliatek's 12.0% achievement is based on a 1.1cm² cell, with two absorber materials.
Record breakers: Heliatek's 12.0% achievement is based on a standard cell of 1.1cm², which uses a combination of two patented absorber materials that convert light of different wavelengths. Using two different absorber materials creates a stronger absorption of photons and improves energetic utilization through a higher photovoltage.
