Studying the difference between the actual output performance and rated output performance for solar cells is not only the key of understanding electrical performance of solar cells, but also the basis of evaluating performance of solar modules in the field. In this paper, the principle of the correction of output performance for photovoltaic cells is discussed. The special experiment setup for testing solar cells performance is built. Then, the current-voltage(I-V) curves of the solar cell under different conditions are measured. The correction coefficients of I-V curves are determined by the theoretical equations and experimental results. The measured I-V curves are corrected to the standard test condition and compared with the rated I-V curve. Finally, the correction errors and the source of errors are analyzed. The relative errors of these corrected parameters are less than 1%, which can meet the requirements of the undergraduate experimental teaching.
