Investigation of Surface Temperature of Solar Modules Using Holographic Overheating Protection

The paper presents the results of an experimental study into solar cell heating under high ambient temperatures of the Republic of Tajikistan. The cell overheating is shown to inevitably lead to their rapid deterioration along with power generation decrease. Infrared thermography was utilized in order to estimate the temperature on the front and rear sides of a solar cell. To reduce the heating, we suggest using a holographic film glued to the entire sensing surface of the cell. Our investigation makes it clear that the temperature of a film-covered cell decreases, while the generated power becomes higher. The obtained results indicate that the glues can indeed be effective to make the most of solar cells as well as prevent their sharp deterioration under high ambient temperatures.
