Boron emitter metallization pretreatment method and application

The invention provides a boron emitter metallization pretreatment method and application, and the method comprises the following steps: carrying out the patterning treatment of the front surface of a half-cell, exposing a part of a boron emitter, carrying out the corrosion treatment of the boron emitter through a corrosion liquid, forming surface active sites, and carrying out the metallization treatment of the surface active sites. The corrosive liquid comprises the following components: water, silver nitrate, hydrofluoric acid, hydrogen peroxide and isopropanol. According to the invention, corrosion treatment is carried out by using the high-acidity oxidant solution, so that an oxide layer and impurities on the surface of the front boron emitter can be removed, and meanwhile, fine recesses and rough surface structures are formed, and fine active sites are formed, so that the binding force between the front boron emitter and metal is increased. 本发明提供一种硼发射极金属化前处理方法及应用，硼发射极金属化前处理方法包括以下步骤：对半电池正面进行图案化处理，露出部分硼发射极
