Dark-field Tester
Product Introduction： Detect the electrical properties of PV cells in the absence of light, such as reverse saturation current, series resistance, and shunt resistance. These parameters reflect the internal structure and material quality of the cells. Evaluate the leakage current of the cells under dark conditions and their response characteristics to low-light environments, providing a basis for predicting the performance of PV cells in practical applications.
