[0002] Leakage current is a key parameter of photovoltaic solar cells. If the leakage current of the cell is too large, it will cause a local hot spot effect after the components are connected in series, thus affecting the use of the components. In the analysis of finished battery products, it is necessary to connect the positive and negative electrodes of the cell through an external reverse voltage. If leakage occurs at a certain position, it will cause overheating at the corresponding position. The leakage position can be locked through infrared thermal imaging, so that the cause of leakage can be further analyzed and identified.
