Cermet Materials, Inc., was founded in 1985 to manufacture powders and thick film pastes for the multi-layer ceramic capacitor (MLCC) and hybrid circuit industries.  Recently, Cermet has introduced screen printable conductive pastes for the photovoltaic (PV) industry.  The years of technical know-how in thick film manufacturing and excellent customer service enabled Cermet to swiftly introduce PV pastes into the market.  Our PV product line consists of Aluminum, Silver/Aluminum,  and Silver thick film pastes for Cz and multi-crystalline silicon applications. Below is a brief description of our product line:

ALUMINUM PASTES

Solus 6200 series are screen printable Aluminum pastes for rear side metallization.  There are fritless, non-leaded and leaded versions of the Solus 6200 series that are aimed to achieve minimal lay down and also to produce a uniform and smooth print after firing.  The Solus 6200 series pastes, when printed and fired above the eutectic temperature of Si/Al, yield a uniformly doped p+ layer without any residual dust.  There are also versions of the Solus 6200 series that are used for rear side passivation applications for both fire-through and non-fire through dielectric layers.  Individual products are summarized below with links to their data sheets

  6214   – Fritted, lead free aluminum paste
  6220   – Fritted, lead free, aluminum paste designed for low bow requirements paste
  6241   – Fritted aluminum paste for fire through applications paste
  

BACK CONTACT PASTES

Solus 6300 series are screen printable silver/aluminum or silver pastes designed for back contact metallization.  The Solus 6300 series pastes are designed with the optimum material composition that reduces the back surface recombination velocity without reducing the adhesion strength of tabbing material.  Cermet’s Solus 6300 series pastes are lead-free and Cadmium-free with a high pull strength and ease of soldering.  Because of high silver prices, Cermet has recently introduced Silver and Silver/Aluminum pastes with Silver contents as low as 50%.  Individual products are summarized below with links to their data sheets:

  6318-55, 50, and 45      – 100%Ag Pastes for polycrystalline cells
  6319-75, 70, 65 and 60  – Ag/Al Pastes for monocrystalline cells
