The light spots of black crystal photovoltaic panels
For photovoltaic modules, hot-spot phenomena are very common and influential, affecting device performance and causing irreversible damage. Researchers mainly pay attentions to hot-spot phenomena from a large-scale view that hot spots result from module failures, i.e., abnormal solar cells in photovoltaic modules are heated by other normal .

In dark images, the cold spots of the PV module are easily recognizable, as seen with the inactive cells in Section 4.2, while in the illuminated images, these spots do not appear, and hot spots are located.
Entire PV panels in the array will be impacted if a single cell or single PV panel experiences shading. Therefore, it's crucial to work on how to lessen the impact of shading on PV.
Different angles and different light intensities have different effects on the performance of solar cells. When the light is radiated to the photovoltaic cell material, some of the incident light is reflected or scattered on the surface, and some of it is absorbed by the photovoltaic cell.
Photovoltaic (PV) modules are devices designed to transform sunlight into electricity. However, they can also work in the same way as a LED: By applying a polarization current, the solar module can be electrically stimulated to emit electroluminescence (EL) radiation.
