Nitrite (NO2−) is one of the common salts in the aqueous aerosol, and its photolytic products, nitric oxide (NO) and hydroxyl radical (OH), have potential for use in the oxidation...

SUMMARYThis paper discusses two brand-new patterning methods for solar cell front metallization by using a layer of amorphous silicon (a-Si) and the laser processed patterning process. These methods have the advantages of simplicity, rapidity, and low cost for the mass production of plated solar cells and also have the potential to overcome the shortcomings of the existing complex processes for Ni/Cu plated cells. In this paper, we reveal the processes and show the metallization performance. The patterning results were disclosed and had the line width of about 45 μm in our experiment. The specific contact resistivity (ρ c ) between plated Ni and silicon wafer exceeded the order of 10 À4 Ω cm 2 . In addition, the patterning mechanisms are also proposed and discussed.
