摘　　要：将酸制绒方式与双层膜工艺进行结合,研究发现酸制绒电池片跟碱制绒电池片相比,除短路电流和效率略低外,开路电压、并联电阻和反向漏电流均有明显优势。在双层膜工艺中,当第一层膜的镀膜时间小于180 s(膜厚小于34.6 nm)时,随镀膜时间增加,总反射率降低,尤其是短波范围,短路电流也因此增加;但大于180 s后,随镀膜时间增加,虽然短波反射率仍降低,短路电流却有所下降。The method of acid texturization with the technique of dual layer anti-reflection coating was studied. Comparing acid textured solar cells with alkaline textured solar cells, except it had lower efficiency and short-circuit current, it had obvious advantage on open circuit voltage, shunt resistance and reverse leakage current. In the experiment of dual coatings, it was found that the total reflectance especially in the short wavelength became lower with the increase of the plating time, thus short circuit current increased when the plating time of the first coating was below 180 s （the thickness of the coating is below 34.6 nm）. But if the plating time was continued increasing, the short circuit current would decline, though the reflectance of the short wavelength still decreased.
