Researchers set new efficiency record for stable binary organic solar cells

A research group led by Prof. Ge Ziyi from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has developed two self-assembled molecules (SAMs) with large dipole moments and employed them as hole-transporting layers (HTLs) in binary organic solar cells (OSCs), achieving highly efficient and stable binary OSCs with a record power conversion efficiency (PCE) of up to 19.70%.
