Value Chain Activity: Manufacturing Chemicals for Solar Industry

The manufacturing of photovoltaic modules, thermal receivers and reflectors requires a number of chemicals and materials for coatings, laminates, photovolatic materals and solar glass. This part of the value chain is a profitable business, evidenced by new entrants from non-polysilicon producing companies, i.e. companies that with no traditional ties to the solar industry.


Here is a list of a selection of companies, which highlights the diversity of companies involved from start-up to established companies that diversify their portfolio.
