Chemical structure of PFFBT4T-C9C13 (PCE12).



Compared to PffBT4T-2OD (PCE11), PffBT4T-C9C13 has larger side chains which help promote better solubility and film morphology. When using PffBT4T-C9C13 as a polymer donor and PC71BM as electron acceptor (with trimethylbenzene (TMB) as host solvent), a higher device performance of 11.7% was achieved [2].

Due to its broader absorption of the solar spectrum in the visible light region (with an absorption edge at about 800 nm), PffBT4T-C9C13 is also ideal for use as a donor material for all-polymer solar cells and NFA-polymer solar cells 

Additionally, its higher solubility means that PffBT4T-C9C13 can be processed with non-halogenated solvents. There are great opportunities with this polymer for inkjet printing on an industrial scale - an environment-friendly approach for alternative renewable energy.
