The lifetime of a photovoltaic (PV) module is influenced by a variety of degradation and failure phenomena. While there are several performance and accelerated aging tests to assess design quality and early- or mid-life failure modes, there are few to probe the mechanisms and impacts of end-of-life degradation modes such as corrosion.
When a PV module is partially or fully shaded, the cells in the shaded area are unable to generate electricity as efficiently as unshaded cells [72, 73, 74, 75]. This can lead to a voltage difference between the shaded cells and the unshaded cells, which can cause PID in the module.
Hot spots in solar cells can lead to PID when the temperature of the hot spot becomes high enough to cause a voltage difference between the solar cell and the module’s frame. This voltage difference can cause an electrical current to flow through the module , leading to the formation of hot spots on the cells.
PV Cracks Solar cell cracks are cracks or fractures that can occur in PV modules, as shown in the example of a solar cell in Figure 12 a. They can be caused by a variety of factors, including mechanical stress, thermal expansion and contraction, and environmental factors such as extreme temperature fluctuations or moisture [80, 81, 82].
The glass/EVA/cell structure also ensured the cells were flat and able to be handled without breakage during the tests. The solar cell top metallization was based on screen printed silver with five (Al-BSF and PERC) or four (SHJ) busbars, and cell interconnects were 1.5 mm wide flat copper wires coated with a lead-tin based solder.
The disproportionality is attributed to the series architecture of solar cell interconnections of conventional modules, but also to the limited amount of incorporated bypass diodes (BPDs) in modules. Usually a BPD is connected in parallel to strings of 15–24 cells to prevent shaded cells from reaching junction breakdown.
