Applications
ETFE top sheets are standard components in flexible thin-film solar module manufacturing, particularly for CIGS and amorphous silicon technologies. This material was used in commercial production at Solopower's Portland facility. The film serves as the outermost protective layer, providing environmental barrier protection while maintaining high light transmittance to the active photovoltaic cells beneath.
This 3M UBF-9L ETFE Ultra Barrier Solar Film is new and unused in its original 3M box. The material was purchased new by Solopower, a flexible solar panel manufacturer based in Portland, Oregon, when they closed operations. It has never been used in a lamination process. The date code on this material is 2012–2013. We are selling it by the linear meter; if you need multiple meters, simply increase your order quantity. Contact us if you are interested in larger full-roll quantities, which range from just under 100 meters to over 300 meters. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
