Photovoltaic nickel paste, preparation method and application of photovoltaic nickel paste in preparation of photovoltaic cell nickel grid line

The invention provides photovoltaic nickel paste, a preparation method and application of the photovoltaic nickel paste in preparation of a photovoltaic cell nickel grid line. The photovoltaic nickel paste comprises the following components in percentage by mass: 1-5% of glass powder, 10-40% of an organic carrier and 60-80% of nickel powder, the organic carrier comprises organic resin and an organic solvent in a mass ratio of (3-7): (2-5). In the sintering process of the photovoltaic nickel paste, the glass powder melts and corrodes the silicon nitride at a high temperature, the nickel powder permeates and forms an alloy with the silicon below to generate ohmic contact, and the problem that a silicon nitride layer is removed before a grid line of a solar cell is electroplated by adopting an existing laser grooving process and a mask/photo-sensitive resist process is solved. 本发明提供了一种光伏镍浆、制备方法及其在制备光伏电池镍栅线中的应用。所述光伏镍浆按质量百分含量计包括以下组分：玻璃粉1～5％、有机载体10～40％、镍粉60～80％；所述有机载体包括质量比为(3～7):(2～5)的有机树脂和有机溶剂。本发明所述光伏镍浆烧结过程中玻璃粉在高温
