Researchers achieve highest certified efficiency of organic solar cells to date

Materials scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have achieved a new record in the performance of organic, non-fullerene-based, single-junction solar cells. Using a series of complex optimisations, they achieved certified power conversion efficiency of 12.25 percent on a surface area measuring one square centimetre. This standardised surface area is the preliminary stage for prototype manufacture. The results, achieved in conjunction with partners from the South China University of Technology (SCUT), have now been published in Nature Energy.
