Abstract.  We discuss fabrication processes for implementing nanometer scale confinement in an organic bulk heterojunction device architecture, including formation and integration of the confining self-assembled template. Such confinement has a beneficial influence on the electrical properties of blended poly(3-hexylthiophene): [6,6]-phenyl-C61-butyric acid methyl ester organic solar cell active layers. Crystallization of the blend upon annealing is inhibited by the confining template, which we understand through analysis of x-ray scattering measurements.
