en Analyzing the Effect of Mixed Solvent Ratios on the Performance of P3HT: ICxA -Based Organic Solar Cells. Research Paper Research Paper 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%. organic solar cells,Chloroform,Chlorobenzene,UV-VIS absorption,Raman spectrum 142 150 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5406-2&slc_lang=en&sid=1 raghad hadi raghad.s.hadi@atu.edu.iq 1800319475328460019118 1800319475328460019118 Yes University of Basra Furqan Almyahi furqan.kasim@uobasrah.edu.iq 1800319475328460019119 1800319475328460019119 No University of Basra
