Adhesion of Screen-Printed Silver Metallization to Crystalline Silicon Solar Cells

Adhesion strength between screen-printed silver busbar lines and the underlying crystalline silicon wafer in photovoltaic solar cells is critically important to the interconnection of cells during stringing operations in module production. Ninety-degree peel tests were carried out to characterize the adhesion of silver busbars to crystalline silicon solar cells. The mechanical properties of the si...
