Small cracks, i.e., below 10%, unlikely influence the output power generation and are relatively equivalent to non-cracked cells. In a comparative evaluation, the output losses (or degradation) are

Cracks that separate important cell parts can significantly reduce power output, especially if they run parallel to the electrical pathways called busbars [11]. These cracks usually form due to

These results confirm to a certain degree that cracks in solar cells are a form of PID; they affect the output power performance and are unlikely to be mitigated.

Reduced Power Output: Cracks disrupt the flow of electricity, resulting in decreased power generation and overall energy production. Hot Spots: When cracks affect individual solar cells, they can create
