PV, the enclosure or cover could be made with the Barix™ Barrier Film from Vitex that was developed for OLEDs.
Thin Film Encapsulation has always been a big problem for flexible OLED displays, because moisture is the biggest problem for organic displays. And until now, it still is. (that's why I'm pretty sure that Qdots will take over the entire OLED industry)
And I think that this is also an interesting development in OLED displays that IMHO could also be used for transparent and flexible solar cells...
