Tech News 1: Alkoxy substitution on asymmetric conjugated molecule enables high-efficiency ternary organic solar cells

[bob_turner]

A research group led by Prof. Ge Ziyi at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has developed an alkoxy-substituted asymmetric conjugated molecule and doped it into the PM6:BTP-eC9-based binary organic solar cells (OSCs) as a third component, resulting in high-efficiency ternary OSCs with a power conversion efficiency (PCE) of over 18.1%.
