Polymer solar cells use a mixture of a light-absorbing conducting polymer as the electron donor and a fullerene derivative as the electron acceptor in the solar cell's photoactive layer. The components are generally mixed together to produce a bicontinuous percolating network called a bulk heterojunction. In a previous paper [21] we developed a systematically coarse-grained simulation model of mixtures of the widely used conducting polymer poly(3-hexylthiophene) (P3HT) and the simplest fullerene C<inf>60</inf>. Here we analyze the ensuing polymer structures and mixture morphologies to understand the local structure of these devices, which provide a crucial basis for the future optimization of bulk-heterojunction morphology. © 2010 Elsevier B.V.en© 2010 Elsevier B.V.
