Abstract

A solar cell was fabricated by different texturing methods using pyramids, acidic solutions and porous silicon. Surface morphology and structural properties of porous silicon have been studied by using scanning electron microscopy and atomic forces microscopy images. Optical reflectance was obtained by using optical reflectometer. I-V characterization of fabricated solar cell was investigated. The results showed that the solar cell efficiencies were 2.76 % for pyramids, 3.34 % for acidic solutions and 11.23 % for porous silicon. Porous silicon texturing revealed an excellent reduction in the reflection of incident light compared with different texturing processes, with a good light-trapping of wide wavelength spectrum, which could produce high efficiency solar cells..
