Abstract
The work presents the design of a diffraction back grating for light-trapping in thin-film GaAs-based quantum dot solar cells. Uni-periodic and bi-periodic gratings made of off-theshelf almost transparent dielectric materials routinely used in photolithography are considered. Gratings are wave-optics simulated by rigorous coupled wave analysis. Optimizing the shape and geometrical aspect ratio of the grating, almost quadrupled photocurrent from quantum dots is demonstrated.
