L8BO

Description

A new high-performance molecular acceptor reported for use in the creation of organic solar cells with 18% efficiency.

“This work reveals the importance of the branched alkyl chain topology in tuning the molecular packing and blend morphology, which leads to improved organic photovoltaic performance.” (1)

• Pairs well with high performance donor polymer “PM6” (also available from Brilliant Matters).
