It can be concluded that the temperature of the PV cell in the cracked area is higher, the I-V curves of the cracked PV modules have a step, and the step exhibits a convex function characteristic. The short circuit current I SC and the open circuit voltage V OC of the PV module in the early stage of the crack are basically unchanged.
