S. K. Kwak, J. H. Oh, and co-workers generate multiple-patterned nanostructures by synergistically combining block-copolymer lithography with nanoimprinting lithography. As described on page 4976, these structures are used as back-reflectors for enhancing light absorption in organic optoelectronic devices including organic photovoltaics and phototransistors. The multiple-patterned electrodes significantly boost the performance of these devices, owing to the highly effective light scattering and plasmonic effects, extending the range of practical applications.
