[11p-W321-6] New Asymmetric Waveguide with Discrete Translational Symmetry for Multi-striped Orthogonal Photon-Photocarrier Propagation Solar Cells
Keywords:solar cell, waveguide, asymmetry
We have investigated a new type of redirection waveguides for concentration solar-cell systems. The solar cell units are to be placed at the peripheral region of the waveguide. The redirection waveguide converts three-dimensionally propagating (3D) photons into 2D photons that propagate in a planar waveguide which serves as the mainstream of the redirection waveguide. In this new waveguide, the cladding layer on one side of the planar waveguide, not being spatially continuous, tangentially touches the core of the planar waveguide which, having an open geometry, is connected, through tributary waveguides, to the bottom plane where the 3D-photons come in vertically.
