【Abstract】 A Keithley 2420 SourceMeter was used to establish a testing system for solar cells and both single index and dual index equivalent circuit model were used to fit the measured data. Many characteristics parameters can be obtained from the data by using the curve fitting technique. The testing results showed that the system has the advantages,such as high precision,anti-jamming,high testing speed and numerical stability. It can be used to test both silicon solar cells and dye-sensitized solar cells and it can carry out long-term real-time testing for solar cells. It provides the basis and foundation for further study of cells.更多还原
