New barrier sheet joins the range
Mitsubishi Plastics has launched Back-Barrier high gas barrier Photovoltaic (PV) back sheet, which is part of its X-Barrier series.

Boasting the world’s highest level of water vapour barrier, the company says that solar cell manufacturers, to whom the company provided samples, confirmed the product’s performance.

In 2008, Mitsubishi Plastics launched the world’s highest level of water vapour barrier properties, with 10-4 g/m2/day. Following this, last year, it launched View-Barrier for use in front panels of electronic devices, including dye sensitised solar cells and organic electro-luminescence display panels that require anti-reflection, UV-cut, anti-glare, low shrinkage and process suitability, in addition to superior gas barrier performance as a substitute for glass plate.

The latest halogen-free product is also able to easily bond to encapsulation material like EVA.  As a result, the product avoids the lowering of electric generation efficiency and strength of the back sheet, thereby contributing to improved durability of solar cells with consideration to the environment, says the company.
