What are solar panel micro cracks?

Solar panel micro cracks, or more precisely micro cracks in solar cells pose a frequent and complicated challenge for manufacturers of photovoltaic (PV) modules.

Why are solar PV cells prone to micro-cracks?

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.
