Abstract :
Recent innovations in high efficiency photovoltaic thermal (PV/T) collectors have made them most suitable renewable energy systems to be integrated in green buildings or utilized in industrial processes. This is attributed to the ability to produce electricity and thermal energy at once. The development in PV/T collectors have reached a new height with the implementation of nanofluids as cooling fluids. Another method that is gaining attraction is the use of Phase Change Material (PCM) to control the temperature of PV panels to maintain its open circuit voltage. This paper aims to review and determine the influence of nanofluids and phase change material on the performance of PV/T collectors in different system configurations (e.g. buildings, both industrial and residential). A comparison between the two, accompanied by an introduction of innovative work in this field is presented as well. The influence of nanofluids and phase change material is immense; from raising the thermal efficiency to raising the operating electrical efficiency and reduce overall payback period of the system. This signifies the importance of performing critical review to establish a clearer understanding of suitable configuration of nanofluid and PCM based PV/T collectors.
