It can cause losses of 0.5 to 1.5 %. It affects only few module types. This power degradation occurs naturally due to physical reaction in the p-n junction of solar cell . The OC voltage and SC current of solar cell are reduced. According to the study , if module manufacturer has considered this effect, then it is not a failure.
PV cells having cracks show different results under same conditions and rise in temperature. The thermal changes in solar cell correlates with speckle pattern and therefore, it helps to estimate size of crack and location of crack in a cell simultaneously.
A solar module's performance can degrade due to gradual reduction in output power or failure of an individual solar cell. Degradation mechanisms include:
The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module's production and handling are not up to the required standards. Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module.
The speckle patterns formed during thermal deformation of PV cell allow to determine type, location and size of crack. A planar heater is used for heat application and about 0.5 °C temperature is required to generate out-of-plane deformation, which makes it easy and fast to apply.
The hotspot formation usually occurs when solar cell/cells act as load instead of producer . It occurs when the operating current of module exceeds short circuit current of shaded or defective cell/cells . The hotspot formation may cause irreversible damage to the cells.
