AbstractWe used solvent-vapor treatment methods to determine nanoscale phase separation and thus tailor the charge mobility of the poly(3-hexylthiophene)/fullerene (P3HT/C-60) blend films. The nanowires obtained by chloroform vapor treatment are rich in C-60, whereas the nanowires obtained by 1,2-dichlorobenzene (DCB) vapor treatment are rich in P3HT. The treated blends offer far superior hole transport than the untreated blends, which is attributed to nanoscale phase separation and a three-dimensional network containing C-60 or P3HT nanowires. Meanwhile, the electrically bicontinuous nanoscale morphology realized by controlling the crystallinity of P3HT and C-60 using different solvent-vapor results in enhanced absorption in visible light without further heat treatment or preparation in both cases. Solar cells fabricating from the films after treatment show several-fold improvements in power conversion efficiency compared to that of devices having films without treatment.
