This study emphasizes on the preparation of the Soybean oil/MXene (SO/Ti3C2) nanofluid, optical and thermal characterization of the nanofluid including suspension stability. The SO/Ti3C2 nanofluid samples are formulated suspending two-dimensional (2D) MXene particles at 0.025{\^a}??0.125 wt concentrations into pure Soybean oil. SEM, UV{\^a}??vis, FTIR and TGA analysis are performed for morphology, optical and thermal stability characterization respectively. Achieved thermal conductivity results of SO/Ti3C2 nanofluid for 0.125 wt of Ti3C2 exhibited 60.82 enhancement at 55 {\^A}oC compared to pure Soybean oil. The specific heat capacity (cp) of formulated nanofluids is measured employing a differential scanning calorimeter (DSC). Maximum cp augmentation is found to be 24.49 at 0.125 wt loading of Ti3C2 in the base oil. Numerical implementation of the prepared SO/Ti3C2 nanofluids on PV/T is performed using COMSOL Multiphysics software resulted noteworthy improvement compared to conventional water, Alumina/water and MXene/palm oil nanofluids as working fluid. Overall thermal effectiveness of the PV/T system is achieved 84.25 using SO/Ti3C2 nanofluids at 0.07 kg/s mass flow rate. Furthermore, employing the nanofluids electrical output of the PV/T is improved by 15.44 in comparison with water/alumina nanofluids at an irradiance of 1000 W/m2 and mass flow rate of 0.07 kg/s. The stated findings indicate overall effectiveness of the Soybean oil based MXene nanofluids over conventional fluids used for cooling purpose in the PV/T collector. {\^A}{\copyright} 2020 International Solar Energy Society}, keywords = {Alumina; Aluminum oxide; Differential scanning calorimetry; Dye-sensitized solar cells; Heat transfer performance; Mass transfer; Nanofluidics; Solar collectors; Specific heat; Thermal conductivity; Titanium compounds; Working fluids, Differential scanning calorimeters; Numerical implementation; Overall effectiveness; Performance optimizations; Photovoltaic thermals; Stability characterizations; Thermal characterization; Thermal effectiveness, Soybean oil, heat transfer; optimization; performance assessment; photovoltaic system; solar power; soybean; thermal conductivity, Glycine max}, author = {Rubbi, F. and Habib, K. and Saidur, R. and Aslfattahi, N. and Yahya, S.
