摘要: We investigated nanotextured Si solar cells using the silver-assisted chemical etching process. The nanotexturing process is very sensitive to concentration of solution. high results in a nanowire formation for nanosurfaces and causes severe surface damage top region micropyramids. These nanowires show excellent light absorption photoreflectance spectra radiative emission photoluminescence spectra. However, low forms nano-roughened provides minority carrier lifetimes. surfaces samples improved electrical cell properties quantum efficiency, conversion fill factor due reduction over-doped dead layer.
