The measurements are performed at Taibah University Faculty of Science, Physics Department, Solar Energy Laboratory, Madinah (KSA). We have measured the IV characteristic of two solar cells, one without cooling system and the other with cooling system using thermoelectric module (TEM). For this
In this experimental work, we have highlighted the effect of temperature on performance of solar cells. We have used the thermoelectric module for cooling the solar cells as indicated in the experimental setup
Referring to the two technologies, a hybrid energy storage system, shown in Fig. 2, is proposed to overcome the difficulties of energy storage for places where the geological structure for PHS and CAES is not suitable. It can be applied mainly for small scale energy storage. The point is the use of the pressure vessel to replace the reservoirs in PSP, where the head of water is provided by the compressed air trapped in the vessel. A micro-pump turbine (MPT) is used to achieve the charging/discharging process, as in PSP. Due to the high cost and construction difficulties of large pressure vessels, the hybrid system is more suited to small scale energy systems, for instance, energy storage for wave energy converters [6] or wind energy [7], where the capacity is no more than 100 kW.
