Resumen:
In this work, poly(3-hexylthiophene-2,5-diyl)/iron (II) disulfide ((P3HT)/FeS2) composites were synthesized by in-situ Grignard metathesis. FeS2 nanoparticles (FeS2 NP) were synthesized using a two-pot thermal method at 220 °C, and subsequently, the in-situ polymerization of 2,5-dibromo-3-hexylthiophene was carried out in the presence of FeS2 NP. The FeS2 concentration in relation to the 2,5-dibromo-3-hexylthiophene monomer was varied in the P3HT/FeS2 composites (3, 4.8, and 7.5 wt% FeS2). The effect of FeS2 incorporation in P3HT on its physicochemical properties was studied by XRD, FTIR-ATR spectroscopy, TGA, cyclic voltammetry, UV–Vis spectroscopy, and SEM (morphology and elemental analysis). The incorporation of FeS2 in P3HT increased the electric charge storage and the grain size. Likewise, the potential of the oxidation peaks of RR-P3HT was modified with the incorporation of FeS2. The composites were tested in the active layer of hybrid solar cells. The photovoltaic devices were characterized by the curves of current vs. voltage to evaluate its performance. The addition of FeS2 in P3HT improved the efficiency of photovoltaic devices by 6.2% compared to those without FeS2 NP. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
