What causes cell cracks in crystalline silicon photovoltaic (PV) cells?

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.

Do cell cracks reduce the intensity of a PV cell/module?

As a potential electrical signature for cell cracks, it has been reported that the intensity of the parallel resistance (Rp: cf. Fig 5A-1) in the AC equivalent circuit of a PV cell/module is reduced by cell cracks that are intentionally introduced in the PV cell/module [33 – 35].

Can cell cracks in a PV cell be quantitatively assessed?

Because this reduction reflects the elevation of the minority-carrier recombination at the p-n junction in the c-Si PV cell, we deduced that cell cracks located in a PV cell can be quantitatively assessed using this electrically measurable signature.

Do cracked PV cells differ from noncracked PV cells?

In fact, the saturation current densities (J01 and J02) of all PV cells have their respective monomodal distributions with a small variation range, and those of the cracked PV cells cannot be distinguished from those in the noncracked PV cells (Fig 12).
