Good Adhesion Solar Cell Paste for Monocrystalline and Multicrystalline

Silicon Solar Cells


BL01A series products was specially developed to apply with higher firing peak temperature process. Innovative technologies and materials allow BL01A to provide efficiency gain to solar cells while keeping up all the other essential characteristics and prove to be standard for the materials manufactured.


A typical aluminum paste contains metal powders, glasses and additives mixed in an organic medium. The Al Paste variables such as metal powder, glass chemistry and additives have an influence on electrical performance, wafer bowing and solar cell adhesion. Increased electrical efficiency is typically not associated with Aluminum Paste, but many customers have seen up to 0.1% efficiency increase with our paste due to improved back-surface-field (BSF) strength.


Al paste designed for crystalline silicon wafer

  • Retaining product lines for Pb contained & Pb free
  • High Voc let it have improved efficiency
  • Uniform and thick BSF forming
  • Excellent physical properties (BOW / EVA PEEL FORCE / HOT WATER TEST)
