What is a crack in a solar cell?

Often cracks are named microcracks or µcrack, and all typically indicate a fracture in the solar cells in the range of mm to as small as in micrometres. Both terms usually suggest the same type of cracks where partially fully isolated areas are developed in the solar cells mainly due to mechanical or thermal stresses 3, 4.

Can solar cell cracks be mitigated?
