Organic photovoltaic (OPV) modules consisting of ITO/ZnO/photoactive layer/PEDOT:PSS/Ag inverted structure were fabricated using slot-die coating method and encapsulated by a barrier film deposited on polyethylene terephthalate (PET). Effective water vapor transmission rate was measured in both the transient and steady-state regimes of PET with a barrier layer. Acceleration tests were conducted under 65℃ and 85% relative humidity to investigate the degradation of OPV modules. Total amount of water vapor into OPV module was calculated and correlated with the degradation rate of it. The lifetime of encapsulated OPV module under ambient condition is calculated and will be presented in the conference.
