PBDB-T

Description

PBDB-T (PCE12) is used in high performance organic solar cells (OPV) (PCE > 12%), mainly in conjunction with the non-fullerene acceptor ITIC. PBDB-T can also be used as a passivation layer that increases the PCE and the stability of a perovskite solar cell (PSC) (PCE > 19%, 90% of peak efficiency retained after 3600 hours).
