Abstract

Contrary to the common expectation that the introduction of the benzene ring should reduce organic photovoltaics performance, the PffBT4T-B polymer used, yielded a dramatically enhanced performance. Systematic morphological and electronic characterizations were conducted and revelaed that talthough PffBT4T-B exhibits weaker Π-Π stacking and lower crystallinity than PffBt4T, the alkyl chains of the PffBT4T-B polymer form a much tighter extent of interdigitation, which can effcetively expel the ITIC-Th molecules from the polymer domain and thus form more crystalline and pure ITIC-Th domain.
