提出了一种新的太阳电池用p型多晶硅片织构化刻蚀方法。在该方法中，我们使用铂或银颗粒作为催化剂，通过化学镀技术将其负载在晶片上。在沉积催化剂之后，在HF溶液中蚀刻和纹理化晶片，在某些情况下向HF溶液中添加化学氧化剂。由织构化晶片制造的太阳能电池（4cm 2）显示出高达16.6%的效率，这比由通过常规碱性方法处理的晶片制造的电池的效率高约1%（绝对值）。
A new etching method for texturing multicrystalline p-type Si wafers for solar cells was developed. In this method, we used platinum or silver particles as the catalysts, which were loaded on the wafers by means of the electroless-plating technique. After deposition of the catalysts, the wafers were etched and textured in HF solution, to which in some cases chemical oxidants were added. The solar cells (4cm2) manufactured from the textured wafers showed efficiency as high as 16.6%, which was about 1% (absolute) higher than that of the cells made from the wafers treated by the conventional alkaline method.
