We report the fabrication and characterization of the photovoltaic cells based on functionalized single wall carbon nanotubes (F-SWCNTs) and poly(3-octylthiophene-2,5-diyl) conductive polymer, P3OT. The multilayered photovoltaic structures were prepared by spin-coating. Synthesis of SWCNTs with diameters smaller than 1.6 nm was done using an original recipe and their functionalization by nitric acid was confirmed by thermogravimetric measurements and field emission scanning electron microscopy (FESEM). We performed first experiments of an active layer formed by different percentages of F-SWCNTs (1%, 2% and 4%) mixed with P3OT, finding an optimal one of 2% mixture, as determined for our prepared structures. Performances of fabricated F-SWCNTs: P3OT based photovoltaic cells were compared with P3OT active layer samples in solar simulator conditions (A.M. 1.5) and the enhancement of specific parameters due to F-SWCNTs addition was proved.
