Poly Vinyl Flouride (PVF) Commonly known as Tedlar is usually used as a back sheet in standard silicon crystalline cell modules. Included is a photo of one of the first modules that I made with a laminator. Ive since had to develop methods to insure all of the small air bubbles are evacuated during lamination. JB

I have seen tedlar sheets on e bay however I was not sure how they are used. are the sheets rigid enough to attach cells to without some other material behind them and an outter frame to support the finished panel? thanks for any info you can provide.
