Using current and voltage sensors and corresponding data acquisition software,we digitize the traditional experiments on measuring the volt-ampere characteristics of solar cells.By using the improved experimental device,the dynamic real-time acquisition of the output current and voltage of the solar cells can be realized.We use the improved experimental device to measure the volt-ampere characteristic curve of solar cells under different light conditions,and calculate the output power characteristic curve.At the same time,we also use the improved device to investigate the effect of photothermal effect on the output characteristics of solar cells.
