Novel edge sealing getter tape: ultra long breakthrough time and high mechanical properties at high temperature

Moisture permeation is widely recognized as one of the most important causes of degradation in time of the performances of photovoltaic modules, especially thin film ones. B-Dry®i is a newly developed edge sealant tape which is able to block moisture penetration into PV modules for thousands of hours in Damp Heat Test (DHT) conditions, thanks to the presence of a getter material. Visco-elastic behavior, even at relatively high temperatures, makes B-Dry® especially suitable to guarantee mechanical stability of PV modules operating in hot and humid climates.
