The present invention discloses in detail a semiconductor device and a patterning method for the plated electrode thereof. By using the laser ablation method according to the prior art, the semiconductor substrate below the ARC is damaged by direct destructive burning. According to the present invention, an additional protection layer is inserted between the ARC and the semiconductor substrate. Then a laser is used for heating and liquefying the protection layer below the ARC, and thus separating the ARC from the liquefied protection layer underneath and forming pattered openings. Afterwards, by a plating process, nickel and copper can plated.

A method for fabricating a silicon-doped or boron-doped aluminum electrode is revealed. Aluminum target or aluminum paste prepared by selectively doped with silicon and/or boron is arranged at a silicon wafer with a passivation layer by physical deposition or screen printing. Then the doped aluminum layer is melted in linear or dot pattern to pass through the passivation layer and contact with the silicon wafer. Thus contact resistance between an aluminum back electrode and the silicon wafer of crystalline silicon solar cells is reduced and acceptor concentration on a surface layer of the silicon wafer is increased. Therefore the process speed is faster and the energy conversion efficiency of the solar cell is improved.

The present invention relates to a preparation method for patternization of metal electrodes in silicon solar cells. After disposing an amorphous silicon layer on a silicon substrate processed by diffusion, laser light is projected on the amorphous silicon layer for patternization, and transforming the amorphous silicon with low optical conductivity into polysilicon with high optical conductivity thanks to the recrystallization process of the laser light. Then, after immersing the amorphous silicon layer in plating liquid, metal electrode can be formed accurately at the spots of the amorphous silicon layer patterned by laser light. No external voltage is required; plating reaction is induced by illumination directly.
