Excellent Bowing Performance Back Side Aluminum Solar Cell Paste for Solar Cell BSF


Description

As the industry pushed towards thinner wafers to reduce material costs, too much bowing will cause cell cracking and breakages. A cracked solar cell typically exhibits lower electrical efficiency and will results in more B-grade cells being produced in the cell manufacturing line. Broken cells create line stoppages, are resource intensive, and can noticeably affect cell production throughout. LEED-INK aluminum paste has excellent bowing performance on 200μm, 180μm and even 150μm wafer thicknesses.
