Solar photovoltaic/thermal technology has been widely utilized in building service area as it generates thermal and electrical energy simultaneously. In order to improve the photovoltaic/thermal system performance, nanofluids are employed as the thermal fluid owing to its high thermal conductivity. This paper summarizes the state-of-the-art of the photovoltaic/thermal systems with different loop-pipe configurations (including heat pipe, vacuum tube, roll-bond, heat exchanger, micro-channel, U-tube, triangular tube and heat mat) and nanoparticles (including Copper-oxide, Aluminium-oxide, Silicon carbide, Tribute, Magnesium-oxide, Cerium-oxide, Tungsten-oxide, Titanium-oxide, Zirconia-oxide, Graphene and Carbon). The influences of the critical parameters like nanoparticle optical and thermal properties, volume fraction, mass flux and mass flow rates, on the photovoltaic/thermal system performance are for the optimum energy efficiency. Furthermore, the structure and manufacturing of solar cells, micro-thermometry analysis of solar cells and recycling process of photovoltaic panels are explored. At the end, the standpoints, recommendations and potential future development on the solar photovoltaic/thermal system with various configurations and nanofluids are deliberated to overcome the barriers and challenges for the practical application. This study demonstrates that the advanced photovoltaic/thermal configuration could improve the system energy efficiency approximately 15%–30% in comparison with the conventional type whereas the nanofluid is able to boost the efficiency around 10%–20% compared to that with traditional working fluid.

“…The performance of an uncovered PV/T collector was investigated with the aim of a mathematical model simulated in TRNSYS by Aste et al (2016). The PV/T consisted of an uncovered mc-Si PV module, bonded with a roll-bond aluminium absorber, a cylindrical storage tank, a loop for forced water circulation and a pump (Figure 2).…”

Hybrid photovoltaic/thermal systems have become an important energy technology due to their capacity of producing electrical and thermal energy simultaneously, their ease of integration into buildings and good overall performance. Conventional PV systems generate waste energy in the form of heat during the conversion of solar radiation into electricity. It has been shown that the electrical efficiency of PV panels decays with the rise in the PV cell temperature. Therefore, PV performance can be optimised if this heat is removed. Air and water are the most common media used for heat removal and the energy can then be used for heating applications in buildings. In the last five decades, researchers worldwide have carried out experimental studies, simulations and numerical modelling of different types of PV/T systems. In addition to water and air, heat removal methods such as refrigerants, PCM, heat pumps and nanofluids have been analysed. This work presents an overview and discussion of the research of the different PV/T thermal control systems of the last five years. The present study highlights key points of the different techniques that exist, such as overall efficiencies, parameters and configurations, type of system, the nature of work, country of development and applications. Based on this study, it was concluded that the PV/T systems are auspicious technology and that further work should be focused on the aesthetics of the systems to promote acceptance and improvement of the efficiency.

“…In an economic assessment of hybrid systems, different hybrid designs were studied and the optimal design was demonstrated, considering a number of constraints [22]. Aste et al [61] proposed a numerical model for water-PVTs simulating, which involved the required parameters Table 1 shows a summary of the studies about photovoltaic thermal systems. Surveying the papers, which concentrated on PVTs, demonstrates that the number of simulation and modeling articles are more than the experimental studies.…”

A main method to increase the solar energy utilization efficiency is to combine heat and power generation together. In this paper, a critical review of the literature on solar combined heat and power systems (CHP) is conducted, which includes solar photovoltaic/thermal systems, concentrated photovoltaic/thermal systems, and various combination with different solar collectors and applications. It shows that there are serious gaps in this field, which calls for more research. The modeling and analysis of the electrical parts of the CHP systems are not adequate, and there are limited studies on the economic and exergy assessments of the solar concentrating CHP systems. The solar collectors for combined CHP were focused on optimizing the performance of the maximum average useful power generation and minimum total heat transfer area, little environment impact analysis was conducted. Careful exergy, economic and environmental analysis on both electronic and thermal performance is suggested, especially for large CHP system.
