  • Diffractive optical element, design method thereof and application thereof to solar cell
    Patent number: 9547181
    Abstract: Disclosed are a diffractive optical element, a design method thereof and the application thereof in a solar cell. The design method for a design modulation thickness of a sampling point of the diffractive optical element comprises: calculating the modulation thickness of the current sampling point for each wavelength component; obtaining a series of alternative modulation thicknesses which are mutually equivalent for each modulation thickness, wherein a difference between the corresponding modulation phases is an integral multiple of 2?; and selecting one modulation thickness from the alternative modulation thicknesses of each wavelength to determine the design modulation thickness of the current sampling point. In an embodiment, the design method introduces a thickness optimization algorithm into a Yang-Gu algorithm.
