    In light of the ongoing demand for more efficient energy consumption and more sustainable energy sources, thermoelectric (TE)-based energy conversion is becoming increasingly significant. Polymer-based composites have grown in popularity in recent years, since they provide far more ecologically friendly options, they are far less expensive, easier to produce and process, and have innately low thermal conductivity. In the present work, polymer composites based on polycarbonate (PC) filled with, single-walled carbon nanotubes (SWCNTs, 0.5 wt %) and ionic liquids (ILs, 0.5 , 3.0 wt %) were studied under the implementation of transient absorption spectroscopy (TAS), in order to shed light on linking the signal of Seebeck coefficient (S) with the optical properties of the composites, under the influence of variant pump fluences. Also, scanning electron microscopy (SEM) was used, in order to study the morphology of the samples as far as their uniformity of their surface and CNT dispersion.
