Keywords:Asymmetrical waveguide

Unlike conventional spectrum-splitting system , which need human to split the spectrum and the performance of the whole system is greatly influenced by the incoming sunlight. In our asymmetric waveguide coupled concentrating solar cells, how to make spatially propagating light efficiently convert into wave light is of vital importance for the research.
