The Influence of Silver Powder Specific Surface Area on the Performance of Photovoltaic Silver Paste
Photovoltaic silver paste is an indispensable core component of solar cells, and its quality directly affects the solar cell performance. Silver paste is typically coated onto the front and back of the cell in a grid formation and adhered by rapid heating (sintering), and the silver grid serves as a highly conductive electron network. Usually, silver powder accounts for 70-90% of the paste by weight, therefore silver material properties will directly affect the overall performance of photovoltaic silver paste. Shape, particle size, dispersion, and specific surface area affect the properties of silver powder.
