Solar Backsheet, PV Photovoltaic Backsheet

Coveme has developed an high performance PET backsheet for photovoltaic modules composed by high grade polyester and special adhesives resistant to hydrolysis and ultraviolet rays. The dyMat PYE range of Coveme laminates protects photovoltaic cells from humidity, atmospheric agents and chemical attacks, guaranteeing total insulation at high voltages.

The cell side is treated with a special thick primer which provides extremely high bonding to EVA. Recently Coveme has developed DyMat PYE 3000, a new high grade PET backsheet for photovoltaic modules that resists to over 3000h DHT (Damp Heat Test).
