An ultraviolet light stabilization additive package is used in an encapsulant material that may be used in solar cell modules, laminated glass and a variety of other applications. The ultraviolet light stabilization additive package comprises a first hindered amine light stabilizer and a second hindered amine light stabilizer. The first hindered amine light stabilizer provides thermal oxidative stabilization, and the second hindered amine light stabilizer providing photo-oxidative stabilization.

UV-light stabilization additive package for solar cell module and laminated glass applications

An encapsulant material includes a layer of metallocene polyethylene disposed between two layers of an acid copolymer of polyethylene. More specifically, the layer of metallocene polyethylene is disposed adjacent a rear surface of the first layer of the acid copolymer of polyethylene, and a second layer of the acid copolymer of polyethlene is disposed adjacent a rear surface of the layer of metallocene polyethylene. The encapsulant material can be used in solar cell module and laminated glass applications.

Encapsulant material for solar cell module and laminated glass applications

A photovoltaic solar cell module and method of manufacture is provided wherein an ionomer is used as an encapsulant, wherein said ionomer being modified by the presence of 0.3 to 2.0 wt. percent of a UV absorber and 0.3 to 2.0 wt. percent of a UV stabilizer.
