Ag electrode glass powder

 

We mainly offer lead-based glass frit powder. These products have extremely good flow characteristics at high firing temperatures and have very high SiN film fire-through(erosion) characteristics. Their ohmic contact is excellent and contact resistance is reduced, contributing to improved conversion efficiency.

Al electrode glass powder

Al electrode glass powder from Central Glass is extremely reactive with Al and Si, and can form a thick and uniform BSF layer when fired. As a result, surface resistance in the vicinity of the Si interface(P+ layer) is reduced, which contributes to increased conversion efficiency.
