Future Timeline

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%.

Their work is published in Angewandte Chemie International Edition.

OSCs have attracted great attention in the field of organic electronic devices due to their advantages of light weight, good mechanical flexibility and translucency. The development of new materials and optimization of the fabrication process have contributed to the rapid improvement in the PCE of OSCs, which has exceeded 19%.
