“…However, in North Africa countries and especially in Tunisia, which is blessed with a significant amount of annual solar irradiation of about 26.13 MJ/m 2 , there was no study of the feasibility of using the ICS in buildings to substitute conventional DHW heating system (gas/gas town) and to challenge the most commercialized solar collector system (FPCDHW system). Indeed, in Tunisia a great interest was given to the exploitation of the flat-plate collector, FPC, DHW system [20][21][22] (Figure 1) to cover Tunisian household's needs. However, the investment costs of the FPCDHW system is until today highly expensive compared to gas/gas town water heater system which is economically non suitable.…”

“…This combination technology [2] has come out as a result of cooling PV panels to avoid the consequences of high cells temperature [3] and consequently to increase the PV panel efficiency [4,5]. Utilization of water, which has the highest thermal conductivity among the used conventional fluids, as a coolant in PVT system [6][7][8][9] showed a higher electrical efficiency compared to PV modules. However, this enhancements were limited and restricted by the low thermal conductivity of the conventional coolants.…”

Although the increment the performance of PVT systems by using the nanofluids as working fluids have gained the attention of researchers during the last two decades, there is still, a lack in the literature study associated to this application. This study contributes to the investigations and researches of applying the nanofluids to increase the performance of PVT collectors. A flat non-concentrating PVT collector has been designed, constructed and outdoor tested in Karabuk University, Turkey. The considered working fluids in this study are MWCNTs (multiwall carbon nanotubes), and graphene nanoplatelets dispersed in water as a base fluid with a concentration of 0.5 wt%. The experiments were run with a volume flow rate of 0.5 L/min for the aforementioned nanofluids and distilled water (as a reference fluid). The study results have shown and revealed that the MWCNT-water nanofluid presented a better performance in terms of electrical energetic efficiency compared to graphene nanoplateletswater nanofluid and distilled water, while graphene nanoplateletswater nanofluid revealed the highest thermal energetic efficiency. Moreover adding thermal unit to PV module enhanced the total energetic efficiency by 53.4% for distilled water, 57.2% for MWCNTwater, and 63.1% for graphene-water.

<span lang="EN-US">Growing concern with regard to energy sources and their usage has consequently increased significance of photovoltaic thermal (PV/T) collectors. A PV/T air collector is a system which has a conventional PV system combined with a thermal collector system. The system is able to produce electrical energy directly converted from sunlight by using photoelectric effect. Meanwhile, it also extracts heat from the PV and warms the fluid (air flow) inside the collector. In this review, solar PV system and solar thermal collectors are presented. In addition, studies conducted on solar PV/T air collectors are reviewed. The development of PV/T air collectors is a very promising area of research. PV/T air collectors using in solar drying and solar air heater.</span>
