Abstract	Photoelectric conversion characteristics of a GaAs solar cell with biomimetic antireflective nanostructure are investigated by using an near-field optical beam induced current (NOBIC) technique. The mappings of the nanostructured profile and photocurrent induced by incident light with different wavelengths can be obtained simultaneously. The measured results of NOBIC show the optical conversion efficiency is mostly harvested near the valley of the nanostructures, which serve as light guides for incident light with three different wavelengths. The observation is consistent with the simulation results using a rigorous coupled wave analysis.
