【摘要】 目前,光伏ZnO靶材与铜基板的连接主要依靠价格昂贵的金属铟。本文分别以贵金属钯、贵金属银、胶体铜为活化液,以甲醛、多聚甲醛、次亚磷酸钠等为镀液还原剂,研究了光伏ZnO靶材的化学镀铜条件,实现了其表面化学镀铜,进而利用普通的价格低廉的钎料SnAg0.3Cu0.7,SnBiAg成功实现了靶材与铜基板的连接。该工艺操作简单,耗费小,在大规模的工业生产中具有广泛的应用前景。更多还原

【Abstract】 In this paper,these were studied that electroless copper plating conditions of photovoltaic ZnO target as substrate,using noble metal palladium,noble metals silver,colloidal copper as activators,and formaldehyde,paraformaldehyde,sodium hypophosphite as reducing agents.The solder connected copper and photovoltaic ZnO target after electroless copper plating could use the ordinary solder(SnAg0.3Cu0.7,SnBiAg,RMB 200～400 yuan/kg)in place of noble metal indium(about RMB 4 300 yuan/kg).It would have broad application prospects in large-scale industrial production because of its low cost and simple process.更多还原
