Micro-cracks represent a form of solar cell degradation and can affect both energy output and the system lifetime of a solar photovoltaic (PV) system. The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module''s production and handling are not up to the ...
The main findings can be summarized as follows: the nonuniformly and uniformly cracked cells are both jeopardized in terms of output power; the loss corresponding to the cell with nonuniform ...

IEC-61215 (International Electro-Technical Commission) for PV qualification standards have stated various failure modes, which eventually lead to micro-cracks and hot-spots in PV cells (Borri et ...
The spatially resolved luminescence appears differently in regions of the solar cell with high resistivity, such as electrically isolated cracks. In this paper, we evaluate how the different aspects of the light induced lateral currents are shown in cracks with different severity levels, compared with a non-electrically isolated area, and a control cell in the same PV …
The main findings can be summarized as follows: the nonuniformly and uniformly cracked cells are both jeopardized in terms of output power; the loss corresponding to the cell with non uniform distribution of cracks is increasingly higher than the uniformly cracked counterpart as the irradiance hitting the cells grows; and all cells …
