The power‐conversion efficiency of an organic photovoltaic cell composed of poly(3‐hexylthiophene) and (6,6)‐phenyl‐C 61 ‐butyric acid methyl ester is enhanced significantly by controlling the surface morphology of the photoactive layer. The hierarchical micro‐/nanostructures of the active‐layer surface are fabricated by nanoimprinting the active layer with a commercially available, anodic aluminum oxide (AAO) membrane filter (see image).
