In this study, a novel nanodome array structure for thin film silicon solar cell is proposed and systematically simulated. This design not only reduces surface recombination, but also achieves a high broadband absorption regardless of the polarisation and incident angles of light, by taking advantage of almost perfect anti-reflection, Mie scattering and Fabry-Perot resonance. The fabrication of such a nanodome structure is technically feasible and the proposed approach is also applicable to other solar cell materials.
