Abstract:

This paper introduced the role， performance requirements， common structures of photovoltaic backsheets as well as the product types， properties and production scales of major domestic backsheet manufacturers. The current situation of raw materials for backsheets such as PET⁃supported membranes， fluorine films， and adhesive was analyzed. Finally， the backsheet market was forecasted， and the new generation backsheet， transparent backsheet， was introduced on the basis of the development trend of photovoltaic backsheets.

Key words: photovoltaic, backsheet, transparent backsheet, poly（ethylene terephthalate） supported membrane, fluorine film
