Abstract:Photovoltaic modules can generate more electricity when receives a big quantity of solar radiation, but the efficiency of (PV) modules will drop when the temperature of solar cells is high. Therefore, reducing the high temperatures of (PV) modules will contribute to increase the electrical efficiency of (PV) modules by extraction the thermal energy associated with the PV modules and achieve an appropriate conversion efficiency of (PV). The aim of the study in this paper is to recognize the performance of hybrid (PV/T) systems in different places, conditions, module designs which can be used in household applications, hotels, etc. Aiming to supply of electricity and thermal energy. The study indicates to use of cooling technique (water or air) to cooling (PV) modules will contribute to a large extent to strengthen the work of solar cells and the efficiency of (PV/T) system as well. And the rate return of the system of electricity and thermal energy will increase, especially when the hybrid photovoltaic/thermal (PV/T) solar systems were properly designed and the conversion rate of absorbed solar radiation for (PV) modules will increase as well.

“…This system contributes to reduction of environmental problems by reduce CO2 emissions are needed in houses and buildings and concentrate on use renewable energy that should be more actively [3], the amount of energy that produce from hybrid PV/T system depend on the photovoltaic which convert only a small part of the absorbed solar radiation into electricity and type of solar cells use, where the greater part of solar radiation converted into heat and that lead to increasing their temperature and decreasing their electrical efficiency [4], Hybrid PV/T system produces electricity and heat (air or water preheating), that will contribute to improve efficiency of PV(/T) modules by extracting the heat loose by using (air or water) as a removal fluid and take this advantage for using in many applications [5]. Several study have been done about using air or water PV/T systems some of research found that use water systems seem desirable because of the nature of this fluid allowing better recovery of the heat [6], while other researches find that the results from an applied air type PV/T system gives a variety of results regarding the effect of design module and operational parameters on the performance of air type PV/T systems [7,8], where can use the air to cool the surface temperature of the PV panel after pick up the surface heat which can use for household application, drying and other industrial purposes [9].…”

International audienceThermoelectric (TE) modules are possible reversible pre-cooling and pre-heating devices for ventilation air in buildings. In this study, the opportunity of direct coupling of TE modules with photovoltaic (PV) cells is considered. This coupling is evaluated through a numerical simulation depending on the meteorological conditions of Chambéry, Alpine region in France, and on the cooling or heating use of the TE modules, through annual energy and exergy efficiencies. For the considered conditions, TE module performances are of the same order as the ones of the vapour compression heat pumps, with a TE coefficient of performance higher than 2 for low values of input DC current. The PV–TE coupling efficiency varies between 0.096 and 0.23 over the year, with an average value of 0.157. Evolutions of the exergy effectiveness of PV and TE elements follow the same trends as the corresponding energy efficiencies but with steeper variations for the coupling exergy yield that varies between 0.004 and 0.014, with an annual average value of 0.010. The direct PV–TE coupling does not seem to be a sustainable option for the summer cooling purpose particularly. A case study with indirect coupling under a warm climate is considered and shows that the use of TE devices could be efficient in housing to ensure summer thermal comfort, but the corresponding necessary PV area would induce a high investment
