| 摘要 |
A method of providing solar cell electrode by electroless plating and an activator used therein are disclosed. The method of the present invention can be performed without silver paste, and comprises steps: (A) providing a silicon substrate; (B) contacting the silicon substrate with an activator, wherein the activator comprises: a noble metal or a noble metal compound, a thickening agent, and water; (C) washing the silicon substrate by a cleaning agent; (D) dipping the silicon substrate in an electroless nickel plating solution to perform electroless plating. The method of providing solar cell electrode by electroless plating of the present invention has high selectivity between silicon nitride and silicon, large working window, and is steady, easily to be controlled, therefore is suitable for being used in the fabrication of the electrodes of the solar cell substrate.
