The invention disclosed an additive for preparing suede on a polycrystalline silicon chip. The invention also provides a suede preparation liquid for preparing suede on a polycrystalline silicon chip, comprising: an acid solution and the aforementioned additive for preparing suede on a polycrystalline silicon chip. The invention also provides a method for preparing suede on a polycrystalline silicon chip, by using which suede can be prepared on the surface of a polycrystalline silicon chip with the foregoing suede preparation liquid. With the use of the additive for preparing suede on a polycrystalline silicon chip in the preparation of suede on a polycrystalline silicon chip, micropore-shaped microstructural suede having an excellent uniformity and no obvious color difference between crystalline grains can be obtained to reduce reflection rate and effectively decrease the number of black lines; by changing reaction mechanism and controlling reaction speed, the additive for preparing suede on a polycrystalline silicon chip disclosed herein enables the preparation of suede at a room temperature, thus greatly reducing temperature control cost, besides, a roller imprint is effectively removed, therefore, the silicon sheet is clearer to be better matched with subsequent procedures to achieve a much stable cell performance. |
