Abstract:
Photovoltaic cells based on P3HT:PC71BM (1:1) mixed with copper phthalocyanine (CuPc) nanoparticles (25:75) were deposited by spin-coating onto substrates made of optical glass, further covered with ITO and PEDOT:PSS. The aim of the present study was to compare the as-prepared solar cells with the “conventional” ones, free of CuPc molecules, in order to investigate if the presence in the active layer of these nanoparticles has any influence on the performance of photovoltaic structures. In this context, we measured the current-voltage characteristics in the dark and under illumination in AM 1.5 conditions (100 mW/cm2), determining the typical parameters in regime of photoelement for both prepared samples. Although the values obtained for the structures containing CuPc nanoparticles are not as promising as expected, when compared to the “conventional” architectures prepared in the same conditions, the OPV cells with P3HT:PC71BM:CuPc nanoparticles composite as photoactive layer still produced few interesting changes intended to improve the performances of the cells acting as photoelement.
