Influence of single-walled carbon nanotubes induced crystallinity enhancement and morphology change on polymer photovoltaic devices.
Single-walled carbon nanotubes (SWNTs) were determined to have significant interaction with poly(3-hexylthiophene) (P3HT), which is helpful to form continuous active film with interpenetrating structure and improve the crystallinity of the resultant film for SWNTs/P3HT composite. Photovoltaic devices based on an active film with relatively higher crystallinity display much enhanced performance. The work function of carbon nanotubes modulated by electron transferring from P3HT to SWNTs is proposed to explain the high open-circuit voltage (V(OC)) obtained from the photovoltaic devices based on the SWNTs/P3HT system.
