We have investigated the performances of the silicon nanowires (SiNW) and silicon nanocones (SiNC) arrays solar cell with different structural parameters. The structural parameters of the thin film solar cell, such as the filling ratio, the period and the length of the nano-wires/cones arrays, can affect the ultimate conversion efficiency greatly. For 3μm SiNW arrays solar cells, with or without the silicon substrates, the obtained corresponding optimizing ultimate efficiency reach to 24.07% and 21.99% respectively, and that of the SiNC arrays solar cells can reach to 31.39% nearly. We have also discussed the simulated results based on the multiple reflection effects, the graded refractive index theory, and guiding mode coupling effect, which will give a guideline for the optimal design of SiNW and SiNC based solar cells..
