摘要：

This paper discussed improvement in the performance of photovoltaic thermal (PVT) system. The effect of different heat extraction medium has been studied. The phase change material (PCM) was used in a combination of different working fluids. The PVT system's performance in terms of module temperature, electrical, thermal, and overall efficiency was compared with a conventional PV panel. The effect of varying flow velocity (4LPM, 8LPM, 12LPM and 16 LPM) of working fluid and variation in concentrations (0.1 vol.%, 0.15 vol.% and 0.20 vol.%) of alumina nanoparticle were examined for improvement in PVT performance. The lowest temperature and highest efficiency of the PV module were observed in the case of 0.15 vol.% nanoparticle in base fluids and 16 LPM flowrates. The phase change material (PCM) has been attached at the back of the PV panel while working fluid was passed through copper tubes submerged in PCM. The PV-PCM system's effectiveness with working fluids (water, water-ethylene glycol, and Alumina/water-ethylene glycol) were compared with conventional PV.
