Nanocomposite barrier films for photovoltaic applications
| DWPI Title: Layered nanocomposite barrier film used for encapsulation of solar photovoltaics and LED applications, comprises layer of dispersed and aligned clay platelets in polyelectrolyte polymer matrix encapsulating photovoltaic module |
| Abstract: Polymer-clay nanocomposites thin film coatings have improved water vapor and oxygen permeability, in addition to improved corrosion resistance, while retaining high transparency, high electrical resistivity, and excellent fire-retardant properties for use as encapsulants for photovoltaic module assemblies and barrier coatings in other photovoltaic applications. |
| Use: The layered nanocomposite barrier film is used for the encapsulation of solar photovoltaics (claimed) and LED applications. |
| Advantage: The layered nanocomposite barrier film has enhanced photovoltaic stability and reliability and excellent electrical insulation property, and is robust, cost-effective, optically transparent and highly impermeable. The composite thin film is flexible, exhibits excellent oxygen/moisture impermeability, corrosion resistance, and resistance to gas permeation and unwanted ion transport. |
| Novelty: Layered nanocomposite barrier film comprises at least one layer of dispersed and aligned clay platelets in a polyelectrolyte polymer matrix encapsulating a photovoltaic module. |
