Major disadvantages of organic solar cell materials are limited absorption and weak charge transport. Here, we have synthesized poly(3-hexylthiophene) nanotubes with a tailored combination of regio-random and regio-regular chains by oxidative polymerization technique, to achieve wide range of absorption (400-720 nm) in visible region. Due to regio-regularity, charge transport follows power law behavior instead of Mott's variable range hopping and the mobility is found to be 2.296 x 10(-2) cm(2) V-1 s(-1), which is comparable to the value reported in the literature. Wide range of absorption and superior charge transport make these nanotubes as important materials in organic photovoltaic applications. (C) 2010 Elsevier B. V. All rights reserved.
