Paper Abstract
We fabricated nanostructured Si/SiO2 superlattice films for solar cell appliactions. The Si/SiO2 superlattice films were fabricated by thermal annealing of a-Si/SiO2 superlattice films. TEM observations revealed the existence of nanocrystalline Si in the Si layer. This sample showed photoluminescence spectrum with peak energy at around 1.5 eV. It was also found that the defect density in the superlattice was reduced by using forming gas annealing. Applying nanosphere lithography and reactive ion etching, we successfully prepared nanostructures on the surface of the superlattice. We also compared the optical properties with the simulation results using rigorous coupled wave analysis.
