Optimization of the Optical Properties of Black Silicon Solar Cell
Black silicon (BSi) is an important texturized form of a semiconducting material used in photovoltaic solar cell technology. It is characterized by surface structuration of silicon with very low reflectance. In this paper, we study the optical properties of black silicon in the visible-near infrared wavelength range. Our work focuses on texturing the silicon surface using cryogenic etching in an inductively coupled plasma (ICP) system. The surface structure of black silicon is formed by varying several parameters of the cryo-etching process, like wafer temperature, / ratio and bias voltage. The microstructure surfaces of BSi can be formed in various shapes (Pyramids, Columns, and Cones forms). The optical properties of the micro-structures were studied by spectrophotometer measurements. The results obtained show that columnar microstructures (CMS) exhibit different texturing shapes under different plasma etching process conditions. The CMS obtained without HF chemical treatment process have a reflectance value as high as about 14%. However, the surface reflectance is reduced to less than 2% in the VIS-NIR range by processing the samples in HF solution.
