Applications

PNDI(2HD)2T, also known as P(NDI2HD-T2), copolymer of naphtalene and bithiophene, is used as a polymer acceptor in high performance all-PSCs.

Compared to PNDI(2OD)2T, PNDI(2HD)2T exhibits a higher degree of crystalline behaviours. This facilitates superior 3D charge-transport between polymer donor and acceptor materials, resulting in enhanced device performance for all-PSCs. 

When PNDI-bithiophene copolymers with different side-chain length were compared, the maximum μe,FET value was identified as 0.39, 1.22 and 1.90 cm2 V?1 s?1 for PNDI(2DT)2T, PNDI(2OD)2T, and PNDI(2HD)2T respectively [2].
