英文摘要	control over polymeric bulk heterojunction (bhj) morphology is one of the key factors in obtaining high-efficiency devices. the domain size influence on device performance is widely considered critical. in this paper, the fibril width of 3,6-bis-(thiophen-2-yl)-n,n'-bis(2-octyl-1-dodecyl)-1,4-dioxopyrrolo[3,4-c]pyrrole and thieno[3,2-b]thiophene (pdbt-tt):[6,6]-phenyl-c-71-butyric acid methyl ester (pc71bm) blend thin film was adjusted by different processing additives. by decreasing the solubility of pdbt-tt in different additives, the fibril width can be decreased from 65.7 nm to 14.8 nm. it is possible that the pdbt-tt seed-crystallite nuclei concentration is higher in the relatively low solubility solvents than that in the relatively high solubility solvents, thus leading to the formation of narrower fibrils. the pdbt-tt/ pc71bm narrow fibrillar interpenetrating network structure was beneficial to exciton separation and charge transport processes. as a result, the solar cell with the narrowest fibril width has a higher short circuit current (j(sc)) and fill factor (ff), thus achieving optimized device performance from less than 1% to 4.75%.
