Product Briefing Outline: Coveme has developed a high performance PET backsheet, ‘dyMat PYE 3000,’ which is claims is able to resist over 3000h of DHT (Damp Heat Test), offering the best performance currently available on the market. The dyMat PYE range of Coveme laminates protects photovoltaic cells from humidity, atmospheric agents and chemical attacks, guaranteeing total insulation at high voltages.

Problem: The demand from solar module manufacturers for a backsheet offering an adequate protection for high performance PV modules. Due to water permeation of the outer layer, the inner PET layer suffers from hydrolysis losing its original properties.Therefore the traditional backsheets is, to a certain extent, unbalanced, having a long lasting outer layer and the inner layer suffering from early aging.

Solution: The dyMat PYE 3000 is the latest development within the well known dyMat PYE range, launched by coveme in 2008, at that time one of the first fluoropolymer free backsheets in the photovoltaic market. It effectively protects solar panels for over 25 years thanks to its superior hydrolysis and UV barrier properties. The dyMat PYE laminate is based on two layers of polyester film. The cell side is treated with a special thick primer which provides high bonding capability to EVA. The primer can be supplied in different colours and in transparent finishing. The laminate thickness has been designed to provide the best combination of properties in terms of electrical insulation and weatherability. It also forms a strong barrier to oxygen and humidity.

Applications: dyMat PYE is suitable for thin film and mono-/ polycrystalline solar modules.

Platform: All complexes of dyMat range are available on request with corona treatment on the cell side. All PYE range has high grade Pet films. Different thickness and primer colour combinations available on request. Available in customized rolls or sheets. Sizes and drills according to customer's drawings.  dyMat backsheets are UL recognized and TÜV certified IEC 60664 and in compliance with IEC 61215 and IEC 61730.

Availability: June 2010 onwards.
