الملخص الانجليزي
Gold nanoparticles (AuNPs) were synthesis by electrolysis method as colloidal nanoparticles and
deposited on both glass substrates and p-type porous silicon (PS) to prepare films by using drop casting
method to improve the performance of PS/Si solar cell. PS was prepared by electrochemical etching pro-
cess (ECE) for p-Si wafers. The optical properties of PS and AuNPs were examined. The structural and
morphological properties for PSi and gold nanostructure (AuNSs) deposited on glass substrate have been
studied by using (XRD) and Atomic Force Microscope (AFM) respectively. TEM testing for AuNPs was
investigated. XRD pattern of PS showed that it had single crystalline structure, whereas for Au nanostruc-
ture it was polycrystalline one. AFM confirmed the nanometric size of both AuNSs and PSi it was around
40 nm for AuNSs and 62 nm for PS. The AuNPs diffusion effect on the electrical properties of PS/Si hetero-
junction was studied. The photovoltaic characteristics of AuNPs/PS/Si/Al Solar cell were reported and the
efficiency of solar cell was 15.67% and F.F is 34.31%.
