摘要
Photovoltaic thermal hybrid solar collectors, sometimes known as hybrid PV/T systems or PV/T systems combines a solar cell, which converts sunlight into electricity, along with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module. The capture of both electricity and heat allow these devices to have higher energy and thus have more overall energy efficiency than solar photovoltaic (PV) or solar thermal collector alone because dual energy from same unit area. Due to the inherent drawback of lower efficiencies of photovoltaic (PV) technologies they face some reluctance from domestic consumers for widespread acceptance. But the lower individual efficiencies of the PV/T collector compared to their individual technologies due to the low solar energy absorption and high thermal resistance between the PV cell and the cooling medium hinders the potential advantages of this hybrid technology. The efficiency of the system gradually decreases with increase in the temperature. Recently, different nanoparticles with base fluid (Nanofluid) are used in this hybrid systems for enhancement of the efficiency of the system as they act as the effective cooling medium. This review paper would give an overview of enhancements in solar PV/T systems with Nanofluid for extensive relevance in energy supply at all levels in the vicinity of future.
