Abstract
AbstractTo develop efficient organic and/or hybrid organic-inorganic solar energy devices, it is necessary to use, among other components, an active donor–acceptor layer with highly ordered nanoscale morphology. In an idealized morphology, the effectiveness of internal processes is optimized leading to an efficient conversion of photons to electricity. Using a poly(3-hexylthiophene)-block-poly(L-lactide) rod-coil block copolymer as a structure-directing agent, we have rationally designed and developed an ordered nanoscale morphology consisting of self-assembled poly(3-hexylthiophene) donor domains of molecular dimension, each of them separated by fullerene C60 hydroxide acceptor domains. Using this morphological control, one can begin to probe structure-property relationships with unprecedented detail with the ultimate goal of maximizing the performance of future organic/hybrid photovoltaic devices.
