The current-voltage (I-V) characteristics of solar cells are an important means to accurately evaluate their performance and diagnose their faults. In this context, five kinds of I-V measurement methods for solar cells (e.g., variable resistance load method, electronic load method, DC-DC converter load method, four-quadrant power supply method and capacitive load method) proposed in recent years are systematically summarized, and their advantages and disadvantages are pointed out. Then, the applications of these I-V measurement methods in extracting the cell parameters and diagnosing the aging of cells and components, partial shading, dust accumulation and short-circuit faults are analyzed. Finally, the development trend of I-V measurement methods for solar cells in the future is prospected, and it is predicted that the DC-DC converter load method and capacitive load method will be the mainstream methods for measuring the current-voltage characteristics.
