7-IV
Used for current-voltage (I-V) characterization of solar cells
The test of the I-V characteristics of solar cells refers to the relationship curve between the current output to the load and the voltage across the terminals under certain illumination. The I-V characteristics can fully reflect the conversion efficiency of solar cells, thus obtaining the final performance index of the solar cells, providing the basis for the production of components and determining the price.
