摘要

A double-cell spectrum splitting scheme for solar photovoltaics is investigated. A simple and flexible design promises both terrestrial and space applications at low costs. The investigation was performed using the Fourier Modal Method based on the scattering matrix formalism. A numerical optimization was done by an evolutionary strategy algorithm. The optimized design is predicted to have over 41% solar conversion efficiency limit cells without sun light concentration. We believe that the proposed design has the potential of becoming a cost-efficient photovoltaic technology.
