Two texturing methods using porous silicon (PS) and pyramids were performed to investigate the effect of them on the performance of crystalline silicon (c-Si) solar cell. Surface morphology and structural properties of samples have been studied using scanning electron microscopy (SEM) and atomic forces microscopy (AFM). Optical reflectance was obtained using optical reflectometer. I-V characterization of fabricated solar cells was investigated. The results showed the highest conversion efficiency of 13.23% for PS layer compared with 11.36% and 3.70% efficiencies for the solar cells devices with pyramids texturing and as-grown Si, respectively. PS texturing exhibited an excellent reduction in the reflection of incident light compared with pyramids texturing process, with a good light-trapping of wide wavelength spectrum, which could produce high efficiency solar cells.
