The key raw material for photovoltaic cell modules is conductive silver paste.The improvement in battery conversion efficiency and module power generation,as well as almost every technological change in the photovoltaic industry, can not be achieved without the contribution of conductive silver paste;And almost every link in the photovoltaic industry chain, from silicon materials to downstream photovoltaic power plant applications, is closely related to conductive silver paste.
The basic preparation process of conductive silver paste is as follows:
Ingredients -Mixing and defoaming machine:to evenly mix the carrier with silver powder and glass powder,avoiding layering.
Dispersion -Three roll grinder: solves the problem of filer dispersion and refinement. Among them, silver powder solves conductivity and oxidation resistance, glass powder solves sintering temperature range and bonding strength, organic metal compounds and oxides solve battery conversion efficiency, resin and solvent solve fine wire screen printing performance, and reduce the volume resistance of silver paste.
