Band gap engineered P3HT/CdPbS composites for utilization of low energy photons.
In the present study, CdPbS composite has been synthesized in the P3HT matrix in a single step. The synthesis has been carried out at a temperature of 120 degrees C by the decomposition of xanthate compound in the polymer matrix. This synthesis method helps in proper distribution of nanoparticles in the polymer matrix. The synthesized materials were characterized using UV-Vis spectroscopy, X-ray diffraction, transmission electron microcopy, photoluminescence (PL) and time resolved florescence spectroscopy. The P3HT/CdPbS nanoparticle composite can absorb photon in the range of 0.7 eV to 2.7 eV and a charge transfer between CdPbS and P3HT has been observed. It has been proposed that this composite may increase both the Voc as well as Jsc by better utilization of solar spectrum and increased charge transfer.
