Madico Receives Patent For Bright White PV Laminate Backsheet


The specialty films division of laminates manufacturer Madico Inc. has been awarded U.S. Patent No. 7,579,083, titled Bright White Protective Laminates, by the U.S. Patent and Trademark Office. The patent covers the use of laminate backsheets for photovoltaic modules that incorporate, among other features, cost-effective thermoplastic EVA, along with white pigment and/or fluorescent agents.

Incorporating EVA into PV backsheets has been proven to improve dielectric properties and adhesion to the encapsulant, according to the company. EVA compounded with white pigments and/or fluorescent agents allows for the power boost.

Madico says its Bright White backsheets increase solar module power by up to 5%, deliver more uniform electrical properties, improve insulation and enhance unit durability.

In addition, the company has a patent pending for its for its Protekt technology, which is differentiated by a fluoropolymer coating that is unencumbered by supply-chain constraints. Protekt-based backsheets incorporate green technology and lean processes that produce sustainable products, Madico says.
