6.5 Conclusion and Outlook

6.5.1 Conclusion

With the rapid progress predominantly in the achievements of material science, the
efficiency of OPVs has boosted significantly to the aim of industrial products. Low
cost and long lifetime are also initially required by the market.
The degradation mechanisms of interface stability in OPVs have been
presented, which are closely correlated with electrodes materials and interfacial
layers modifying the electrode/organic interface due to the diffusion of oxygen and
water into these layers and also their intrinsic properties.
In order to well understand the mechanisms, highly effective characterization
techniques are of great significance to monitor and analyze the origins of interface
instability and the degree of their influence. These characterization techniques, in
