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.
Illustrated in Fig. 4 is the correlation between solar cell efficiency and temperature. As temperature rises, efficiency experiences a decline attributed to heightened electron–hole recombination rates and alterations in the bandgap properties of materials.
The overall power coefficient is negative, indicating decreased efficiency at higher temperatures. Contrary to what one might expect, solar panels actually become less efficient as they get hotter. This inverse relationship between temperature and efficiency is due to the physics of how solar cells work.
High-efficiency solar cells can convert a larger portion of sunlight into electricity, reducing the number of cells and surface area required to generate a given amount of power.
