摘要
A photovoltaic cell is provided. The photovoltaic cell includes a concentrator optic structure separating the solar spectrum of light into a plurality of spectral bands. The concentrator optic structure focuses these spectral bands into a plurality of concentric tightly focused ring-shaped spots and a central round spot. A multitude of circular sub-cells are each approximately positioned at a ring-shaped spot associated with a respective spectral band produced by the concentrator optic structure. Each of the sub-cells stores the energy produced at the respective spectral band
