Does water cooling affect the efficiency and temperature of a PV cell?

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.

How does temperature affect a solar 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.
