N2 - In the last decades, organic electronics has become an important field due to their numerous advantages, among others low-cost processability, high scalability, flexibility, light weight and short energy payback time. However, due to their organic nature, the functioning of the devices is impaired in the presence of oxygen, light, heat and humidity — factors found in a normal working environment. Several directions can be followed in order to minimize these losses. Main strategies include development of efficient encapsulation layers, implementation of additional barrier and UV blocking layers, synthesis of intrinsically more photochemically stable active layer materials, and stabilization of active layers by blending of stabilizing compounds such as antioxidants, radical scavengers and UV absorbers. This chapter places the focus on additive-assisted stabilization of organic devices, specifically organic photovoltaics. In this context, we are going to give an overview of the main classes of compounds that are being used for this purpose, and discuss the role of additives to promote both photochemical and morphological stabilization. The chapter will give an overview of the existing results in the field, along with an extensive collection of additives known to have been tested in different organic devices.
