Abstract:

Abstract: A model of silicon solar cells based on its output characteristic was built in this system, by using LabVIEW

as software. Output characteristics of silicon solar cells and the maximum power point tracking system were simulated under

different solar intensities. The influence of the dark current on the maximum power point and the fill factor of silicon solar

cells were also simulated. The simulation results verify the nonlinear output characteristics of silicon solar cell, and the

effectiveness of this system in determining the most appropriate load to stabilize the maximum power point of the cell. And the

conclusion that the correlation between the optimum matched resistance and the solar intensities is hyperbola, which was drawn

by analyzing the simulation results. It was also proved by the results that the dark current is a key factor to the maximum

power point and the fill factor of silicon solar cells.
