Abstract

The solar cells have been fabricated based on porous silicon with N (111) and N (100) which prepared by electrochemical etching with an electrolyte solution HF: ethanol in the ratio of 1:3 Surface morphology and structural properties of nanostructures were characterized by using scanning electron microscopy (SEM) .Optical reflectance was obtained by using optical reflectometer. I-V characterizations were studied with 80 mW/cm2 illumination conditions. Porous silicon N(100) revealed as excellent anti-reflection coating versus incident light when it is compare to porous silicon N(111) antireflection coating as well as it is given a good light-trapping of wide wavelength spectrum, which could be produced a high efficiency solar cells.
