In this study, a flattened light-scattering substrate (FLiSS) with a large refractive index contrast in plane is investigated as an approach for overcoming the detrimental effect of highly textured substrates for obtaining better light management in thin-film silicon solar cells. A FLiSS composed of a two-dimensional ZnO grating and a Ag reflector realize a high open circuit voltage in substrate-type microcrystalline silicon solar cells irrespective of the grating structure, with an enhanced infrared response. The optimum FLiSS structure is discussed with the help of numerical simulation.
