摘要
We demonstrate the use of polyisobutene (PIB) in a glass encapsulation method suitable for organic devices. The PIB viscosity at environmental temperatures provides a fast and non-aggressive passivant layer formation method for device protection with glass. Due to its fully aliphatic character, PIB is suitable for passivating organic light-emitting and photovoltaic devices. The observed preservation of encapsulated Ca films demonstrates the PIB suitability for air-unstable metals passivation. Stable I(V) characteristics and increased operational lifetime were observed in PIB-encapsulated organic devices. This encapsulation method is cheap, simple, and dispenses intensive equipment use, so that it is appropriate even for laboratories with restricted experimental facilities.
