Customer ServiceSolar cells and modules generate and dissipate heat aside from converting sunlight to electricity, causing their temperature to rise above the environmental temperature. This heating can increase module and system costs by lowering electrical output and shortening the module lifetime.
Abstract: The heat dissipation has been rarely investigated in solar cells although it has a significant impact on their performance and reliability. For the first time, an extended three-dimensional (3-D) simulation of heat distribution in perovskite solar cells is presented here.
Thermal effects in the context of solar cells refer to the changes in their electrical and optical properties due to variations in temperature. As solar cells operate, they invariably generate heat.
The most important criterion for judging the effect of cell and module heating is its influence on the cost of the generated energy. Ultimately, the influence of thermal effects on the electrical performance and reliability of a module will be reflected in the PV system’s energy cost.
The orientation of solar panels, whether facing north–south or east–west, significantly influences the amount of sunlight received and, consequently, solar cell temperature (Atsu et al., 2020). The direction in which panels are oriented determines their exposure to direct sunlight.
Temperature variations influence the bandgap properties of materials within solar cells (Asif, et al., 2023). Bandgap, representing the energy difference between valence and conduction bands, plays a crucial role in photon absorption.
