单晶硅绒面减反结构制备技术研究

In the technology of solar cell production , the surface structure is critical,the main purpose is to reduce the reflectance of sunlight, thereby improving the light absorption to improve photoelectric efficiency. The paper using chemical etching to get the ideal textured structure.The isopropanol concentration, temperature and corrosion time effecting on the morphology of suede were researched, using SEM for surface samples were observed after the reaction, and we have done the comparative analysis on experimental results .The results show that silicon in 2wt% NaOH and 12wt% IPA mixture, at 80℃,corrosion 50min,we can get a small size, distribution, morphology ideal textured structure.
