Front (Substrate) and Back (Cover) Glass
Laminated glass sheets are heat-strengthened to withstand handling and thermally induced stresses, while avoiding breakage over the 25+ year module life.
Semiconductor
CdTe compound semiconductor material forms the active photovoltaic cells, which convert sunlight into electricity.
Laminate Material
Used to bond the cover glass to the substrate, sealing the photovoltaic device from the environment.
