摘要：
本发明公开了一种高均匀性含丹皮酚的单晶硅太阳能电池片表面织构液，其是由下述重量份的原料制得：丹皮酚0.05‑0.1，苯乙烯1.5‑2.5，5‑10%过硫酸铵溶液1‑2，十二烷基硫酸钠0.1‑0.2，十二氟庚基丙基三甲氧基硅烷0.1‑0.15，N‑油酰基‑N‑甲基牛磺酸钠0.1‑0.15，羧甲基纤维素0.03‑0.05，氢氧化钠3‑5，柠檬酸0.3‑0.5，木糖醇0.3‑0.5，水100‑120。本发明的硅片织构液反应速度较快，腐蚀适中、减薄量小、重复利用率高，制得的绒面金字塔分布、大小均匀，颗粒较小，并且工艺加工质量稳定性好，硅片表面质量高。
摘要（英）：

The invention discloses high-uniformity paeonol-containing single crystalline silicon solar cell surface texture liquid. The single crystalline silicon solar cell surface texture liquid is prepared from the following raw materials in parts by weight: 0.05-0.1 part of paeonol, 1.5-2.5 parts of styrene, 1-2 parts of 5-10% ammonium persulfate solution, 0.1-0.2 part of sodium dodecyl sulfate, 0.1-0.15 part of dodecafluoroheptyl-propyl-trimethoxylsilane, 0.1-0.15 part of N-oleoyl-N-methyl sodium taurine, 0.03-0.05 part of carboxymethylcellulose, 3-5 parts of sodium hydroxide, 0.3-0.5 part of citric acid, 0.3-0.5 part of xylitol and 100-120 parts of water. The silicon wafer texture liquid disclosed by the invention is relatively high in reaction speed, moderate in corrosion, small in reduction amount and high in repeating utilization rate, prepared textured surfaces are in pyramid distribution and are uniform in size, particles are smaller, the technology processing quality is high in stability, and silicon wafers are high in surface quality.
