Asymmetric Waveguide-Coupled Scheme for Multi-striped Orthogonal Photon-Photocarrier-Propagation Solar Cell (MOP³SC)

Abstract

Investigated are asymmetric redirection waveguides that are to couple to a solar-cell unit placed at the end, converting 3D-photons of sunlight to 2D-photons. The redirection waveguide is equipped with two functions, the first of which is to make the 3D-photons coming from various directions go vertically with respect to a 2D-waveguide. The second function is to change the vertically going photons into lateral photons propagating in the 2D waveguide. The redirection waveguide can harvest photons coming in wide area and convey them to the solar-cell unit located at the periphery of the 2D waveguide, as a key element of concentrator solar-cell with high conversion efficiencies as well as of optical wireless power transmission systems.
