NOVELTY - A light splitting-based photovoltaic system comprises light concentrating lens, light parallelizing lens (130), light splitting prism, mirror-based light recycling structure, and photovoltaic cells. The light concentrating lens is at the forefront. The light parallelizing lens is under the concentrating lens. The light splitting prism is underneath the light parallelizing lens. The photovoltaic cells have different band gap energies. The photovoltaic cells and mirror-based light recycling structure are beneath the lenses and prism.    USE - Light splitting-based photovoltaic system for generating electricity.    ADVANTAGE - The light splitting-based photovoltaic system provides high intensity, efficiently converts light energy into electricity, eliminates the problems in the prior art system by separating frequency components of light more spatially, and prevents unwanted irradiation from reaching the cell, thus improves performance of the system. The light splitting-based photovoltaic system allows the installation of the photovoltaic cells at the positions that correspond to spectral bands at a right angle with the light beam, and covers the whole photovoltaic cells with mirrors (except the light entering hole) to redirect the reflected light onto the photovoltaic cells.    DETAILED DESCRIPTION - A light splitting-based photovoltaic system comprises light concentrating lens, light parallelizing lens, light splitting prism, mirror-based light recycling structure, and photovoltaic cells. The light concentrating lens is at the forefront. The light parallelizing lens is under the concentrating lens. The light splitting prism is underneath the light parallelizing lens. The photovoltaic cells have different band gap energies. The photovoltaic cells and mirror-based light recycling structure are beneath the lenses and prism. The mirror-based light recycling structure covers photovoltaic cells. An INDEPENDENT CLAIM is included for light splitting method comprising concentrating the light using the concentrating lens such as Fresnel lens or glass convex lens, parallelizing the concentrated light by placing the parallelizing lens having short focal length in a place where its focal point (120) coincides with the focal point of the concentrating lens, and splitting the concentrated light into many spectral bands by placing a prism immediately after the parallelizing lens.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of the overall structure of light-spitting based photovoltaic system.    Focal point (120)    Light parallelizing lens (130)
