Water cooling is one of the most efficient methods in PV cells thermal management. In the present article, numerical simulation, on the basis of computational fluid dynamic, is performed to investigate the influence of solar irradiance, ambient temperature and speed of wind on the efficiency and temperature of a monocrystalline cell.
As the temperature increases, the electrons in the solar cell become more energetic, reducing the bandgap of the semiconductor material. This leads to several effects: Decreased Open-Circuit Voltage: The most significant effect is a reduction in the cell’s open-circuit voltage. This decrease is typically around 2.2 mV per °C for silicon cells.
Solar cell immersed in water was monitored under real climatic conditions, cell surface temperature can be controlled from 31-39 . C. Electrical performance of cell increases up to great extent. Results are dicussed; panel efficiency has increased about 17.8% at water depth 1cm.
Even if the thermal power efficiency of 58% gained from the typical operating conditions has sufficient capacity for heating water for household use (Chen and Riffat 2011 ), most PV panels convert around 85% of the sun’s energy into heat, which is causing the operating temperature to rise (Li et al. 2002 ).
C. Electrical performance of cell increases up to great extent. Results are dicussed; panel efficiency has increased about 17.8% at water depth 1cm. The study can give support to the Concentrated Photovolatics System by submerging the solar cells in different mediums.
The water-cooling effect kept panel temperatures an average of 10°C lower than the land-based system during summer months. A combined solar and agricultural installation in France used raised solar panels to provide partial shade for crops. This not only improved crop yields but also kept the panels cooler.

As the collection voltage is similar to that of the low-temperature solar cell in the annealed state and the shunt resistance is even a bit lower compared to the low-temperature device, it can be concluded that the higher FF of 73.2% after 30 min annealing for this solar cell can be related to the significantly lower series resistance of R s = 5.4 ± 0.1 Ω cm 2 in the device.
