Top 10 photovoltaic paste companies in China

Photovoltaic paste is the core auxiliary material in the production of photovoltaic cells, accounting for more than 30-40% of the non-silicon cost of cell manufacturing, and about 10% of the total cost of cells. Next, we will compare the respective advantages of photovoltaic paste companies in China.
Photovoltaic silver paste is a mixture of high-purity silver powder (conductive phase), glass oxide (bonding phase), organic resin and organic solvent (organic carrier), which is a uniform paste formed after stirring and three-roll rolling. Photovoltaic cell electronic paste is mainly classified into:
  1.  Back silver pastep;
  2. Back aluminum paste;
  3. Front silver paste.
