A WEATHERABLE COMPOSITE FOR FLEXIBLE THIN FILM PHOTOVOLTAIC AND LIGHT EMITTING DIODE DEVICES

摘要

The invention provides a weatherable composite including a moisture barrier system having a moisture vapor transmission rate at or below 1 x 10-2 g/m2 /day, at least one weatherable layer or coating, and a substrate that is disposed between the moisture barrier system and the weatherable layer or coating. The weatherable composite may be adhered to one or both sides (e.g., front and back) of a photovoltaic thin-film cell or organic light emitting diode such that the weatherable layer(s) or coating side(s) of the weatherable composite is exposed to the environment. The weatherable composite protects the device from both moisture and UV exposure.
