SOLAR CELL MATERIALS
 Mereco Technologies Group Inc., comprised of the Metachem Resins
Corporation and DMS, supplies high quality low cost aluminum paste
for the back surface metallization of silicon solar cells.
Because Mereco does not have the cost structure and overhead of
larger suppliers of aluminum paste, we can provide you with the most
cost effective economic approach to your aluminum paste
requirements.
With over 10 years of experience supplying proprietary customers
worldwide, Mereco chemists, materials scientists, and engineers,
combine extensive experience in metal powder, binder, glass frit,
and solvent technology to provide state of the art aluminum paste
products for the manufacture of solar cells.
 Conducting extensive evaluations of the proper formulations of
powder, glass, binder, and solvent, Mereco scientists can tailor the
paste to your specific processing and firing conditions. Pastes can
be formulated for either screen printing or tampon printing
operations.
Mereco’s new low bow formulations are designed around proprietary
powder and lead-free and cadmium-free glass frit technology and can
result in excellent bow results on all size and thicknesses of
wafers.
