Silver (Ag) paste is integral to solar cell manufacturing, primarily serving as a conductive material in photovoltaic (PV) cells. Its applications include:
Front-Side Metallization: Ag paste is applied to the front side of solar cells to form fine gridlines, facilitating efficient electron collection and enhancing overall cell performance.
Back-Side Metallization: On the rear side, Ag paste creates a conductive layer that aids in electron flow, contributing to the cell's electrical efficiency.
Passivated Emitter and Rear Cell (PERC) Technology: In PERC cells, Ag paste is used to form rear contacts, improving light absorption and increasing cell efficiency.
