Various cell crack modes (with or without electrically inactive cell areas) can be induced in crystalline silicon photovoltaic (PV) cells within a PV module through natural thermomechanical stressors such as strong winds, heavy snow, and large hailstones.
Often, mechanical loads induce cracks in wafer-based solar cells, which usually lead up to 2.5% power degradation in 60-cell PV modules, in the case the cracks do not isolate cell areas . Furthermore, PV modules may exhibit cracks causing inactive cell areas after 15 years of operation.
A classification of cracks based on their characteristics is presented. An overview of experimental and numerical studies on cell cracks is conducted. The effect of cracks on the electrical characteristics of PV modules is debatable. The prediction and quantification of their long-term impact is not known yet.
The presence of cracks in PV panels can have a substantial effect on their overall performance and efficiency. Cracks in the panel cause a decline in the electricity output of the solar PV system, resulting in diminished overall efficiency.
