This study proposes a numerical approach based on the finite element method to assess the impact of cracks in solar cells on the mechanical response of photovoltaic panels.
Cell cracking presents a serious risk for the long term reliability of c-Si photovoltaic modules. Cracks may not initially result in performance loss, but over time performance may degrade as the module
Different values of the fracture toughness of the grain boundaries to the fracture toughness of the grains were used in isotropic and anisotropic models in order to identify the crack pattern in
The reason of the difference of characteristic fracture strength was analyzed based on the surface morphology, roughness, and the saw marks of silicon wafer. In this paper, the fracture
