Zusammenfassung:In this work nanocrystalline porous silicon (PSi) prepared by electrochemical etching of p type silicon wafers. PSi is characterised by means of XRD, FTIR and AFM. Crystallites length become expected with the aid of X-Ray diffraction. Atomic Force microscopy confirmed the nanometric size. Colloidal Al2O3 nanoparticles prepared via electrolysis method and deposited using drop-casting method as a thin film. The structural, morphological, optical homes of Al 2 O 3 NPs were investigated. The effect of Al 2 O 3 NPs diffusion at the holes of PSi sun mobile have stated which exhibits an improvement in (Ag/Al 2 O 3 /PSi/Si/Al) solar cell performance.
