Luminescence mechanism of avalanche breakdown was figured out by Si band structure. Early breakdown was found to be consistent with the Zener effect. This work provides achievable methods for analyzing solar cell breakdown mechanisms. The local breakdown behavior may be harmful to solar cells and could possibly permanently damage the cell.
According to NREL, modules can fail because of unavoidable elements like thermal cycling, damp heat, humidity freeze and UV exposure. Thermal cycling can cause solder bond failures and cracks in solar cells. Damp heat has been associated with delamination of encapsulants and corrosion of cells.
When a specific cell in a solar module is shaded — caused by leaves falling from trees, by shading from buildings or even by animal stools, for example — it operates at a lower photocurrent. The higher current generated by the other, unshaded, cells in the module is then forced to pass through the shaded cell in reverse.
Solar cells are devices for converting sunlight into electricity. Their primary element is often a semiconductor which absorbs light to produce carriers of electrical charge. An applied electric field can then sweep these carriers out of the semiconductor, thus producing an electrical current.
