The metal phase that plays a conductive role is the core of the paste system. Taking stock of the development history of mainstream battery routes, among the photovoltaic pastes used in mass production lines, only silver and aluminum are selected as the conductive phase. In addition, according to the doping type of the silicon wafer substrate, the application areas of silver paste and aluminum paste are different: aluminum paste is usually used for the P side, and silver paste is used for the N side. Looking at the development history of aluminum system pastes in combination with the process of battery technology iteration, the application of aluminum paste in photovoltaic cell technology is not only for electrode conductivity. The three main functions of aluminum paste on the back of BSF batteries are: 1) Passivation. The solubility of impurities in aluminum is greater than that in crystalline silicon, so it can absorb impurities such as iron, cobalt, and nickel in P-type silicon to improve the conversion efficiency of the battery cell. 2) Doping. Aluminum, as a +3 valence element, diffuses into silicon to form a P+ layer, forming a high-low junction with P-type silicon, hindering the diffusion of electrons to the back, thereby reducing back recombination. 3) Conductivity. The atomic radii of aluminum and silicon are close, and they diffuse into each other at a certain temperature to form an alloy junction, that is, an ohmic contact, and the contact resistance is reduced. The fine grid aluminum paste used in PERC cells has two functions: 1) Doping. The local aluminum paste contacts the P+ layer in the PERC structure, which acts as a back field and reduces the back recombination rate. 2) Conductivity. Aluminum and silicon dissolve each other to form local point contacts.
