Abstract: (5050 Views)
In this investigation, a formulation was developed as a solution and thin films by combining poly (3-hexylthiophene) (P3HT) and fullerene Indene-C60 multi-adducts (ICxA) with varying solvent ratios. The formulations were prepared under ambient conditions. Morphological parameters were assessed utilizing a transmission electron microscope, scanning electron microscope and complemented by optical microscope pictures. UV-Visible absorbance and photoluminescence (PL) measurements were implemented to investigate the optical properties of active layers The values of the energy gaps of the prepared thin films and solutions increased as the solvent ratios of chlorobenzene to stander solvent increased, as a result of the isolation of P3HT chains from their neighbours. The Raman spectra are associated with high aggregation of composition and increased conformation when the intensity ratio (IC= C/IC-C) is small and the full width at high maximum (FWHM) is low. In ambient conditions, organic photovoltaic cells (OPVs) are produced with varying solvent ratios. The device with a 30% ratio exhibited the highest performance, with a power conversion efficiency (PCE) of approximately 1%, an open circuit voltage (VOC) of 0.571 V, a short circuit current density (JSC) of 7.47 mA.cm-2, and a fill factor (FF) of 38.6%.
