Inhibition of Photodegradation Processes by Additive of Fluorinated Carbon Nanotubes into the Active Layer of Organic Photovoltaic Cells

The composites based on a semiconducting polymer and a modified fullerene were deposited as active layers of organic photovoltaic cells (OPCs). Fluorinated carbon nanotubes were added into the composite according to the procedure described previously [Kobeleva, E.S. et al., Fuller. Nanotub . 31 , 46...

Description
Summary:The composites based on a semiconducting polymer and a modified fullerene were deposited as active layers of organic photovoltaic cells (OPCs). Fluorinated carbon nanotubes were added into the composite according to the procedure described previously [Kobeleva, E.S. et al., Fuller. Nanotub . 31 , 464 (2023)]. The admixture inhibited photodegradation processes within OPC samples. This phenomenon is due to several reasons, in particular, the fixation of the optimal nanostructure of the bulk polymer : fullerene heterojunction and inhibition of the processes of morphological degradation of the active layer.
