Abstract: The article investigates the detrimental effect of nonuniform and uniform crack distributions over a solar cell in terms of open-circuit voltage ( ${{bm{V}}_{{{bf oc}}}}$), short-circuit current density ( ${{bm{J}}_{{{bf sc}}}}$), and output power, the latter under a wide range of irradiance conditions.The experimental procedure to detect the cracks …
Micro-cracks in silicon wafers and solar cells are a well-known problem in the PV industry. This type of defect is becoming more common as the wafer thickness is reduced following a recent change in wafering technology from …
When cracks are present in Silicon-based solar PV cells, parts of the cell become inactive electrically. This has a notable impact on the power output [ 11, 12, 13 ]. In order to assess how the area of inactive cell area ( (A_{ina}) ) influences the PV module output, the I-V and P-V characteristics are studied using MATLAB/Simulink …
