Abstract

The working fluid influences on energy performance of a solar photovoltaic/thermal (PV/T) module are investigated experimentally, the MXene, ethylene glycol (EG) and distilled water (DIW) are considered in this study. The effects of a liquid optical filtration layer on the working fluid temperature and module transmittance property are clarified, and the pressure drops and pumping power of the PV/T module with different working fluids are determined. A brief uncertainty analysis is carried out, which exhibits that the measurements are sufficiently accurate to reflect the experimental data variations. Experimental results demonstrate that the total energy conversion efficiency of the module using the MXene is 31.1% and 12.7% higher than those using the EG and DIW respectively. It is also found that the transmittance performance of the MXene optical filtration layer is 4.6% and 2.2% higher than those of the EG and DIW respectively. Additionally, it is concluded that the maximum pumping power of the module using the MXene is 9.8% and 18.22% higher than those using the EG and DIW respectively, which indicates that more pumping power is needed for the MXene based PV/T module.
