PJ71, for high efficiency polymer solar cells applications

High purity polymer available for fast, secure dispatch


PJ71, BDTT-FBTA back-boned donor-acceptor type polymer semiconductor, with tripropylsilyl substituents on thiophene groups that are conjugated side chains to the BDTT unit, it further down-shifts the HOMO energy level and thus increases the bandgap of the polymer (Eg = 2.16 eV).

The Si-binding atoms also have a significant effect on the crystallinity of the polymer thus the morphology of the device film due to the longer C–Si bond length compared with the C–C bond, giving the rise of stronger π-π stackings between each polymer chains.

PJ71 is used for high efficiency polymer solar cells applications especially with ITIC series as NFAs.
