Hybrid nanostructures,comprising of a metal core and a semiconductor shell layer,show great potential for a new generation of low-cost solar cells due to their unique electronic and optical properties.However,experimental results have fallen far short of the ultra-high efficiency (i.e.beyond Shockley-Queisser limit) predicted by theoretical simulations.This limits the commercial application of these materials.Here,a non-transparent organic solar cell with an array of Ag/ZnO nanowires has been experimentally fabricated to increase the intal quantum efficiency (IQE) by a factor of 2.5 compared to a planar counterpart.This result indicates a significant enhancement of charge collection efficiency due to the ultrafast Ag nanowire channels.This hybrid nanostructure can also serve as a perfect back reflector for semi-transparent solar cells,which can result in enhanced light absorption by a factor of 1.8 compared to the reference samples.The enhanced charge collection and light absorption can make these Ag/ZnO nanostructures available for the application of mod optoelectronic devices.
