As the solar industry accelerates toward higher efficiency and lower cost-per-watt, precision abrasives play a vital role in wafering, edge grinding, and surface finishing of photovoltaic materials. Our silicon carbide and alumina abrasives are optimized for monocrystalline and polycrystalline silicon processing, offering high material removal rates and exceptional surface quality for solar cell production.
High-purity SiC abrasives ensure precise cutting with reduced kerf loss and wafer bow in wire sawing operations.
Medium-grit silicon carbide removes edge microcracks, preventing cell breakage during handling and cell stringing.
Fine-grade abrasives create uniform backside roughness for enhanced passivation and bonding performance.
Alumina abrasives clean module backsheets and frame surfaces before adhesive application or laser soldering.
Brown fused alumina is used to smooth aluminum frame edges and prepare for coating or sealing.
Specialized abrasives enhance light trapping by creating controlled roughness on silicon wafer surfaces.
