灯光下多晶硅太阳能电池的特性函数拟合

In this paper, we have done experiment under the known theory of solar. In the constant temperature dark room with 60-watt incandescent light exposure to solar panels to do experiments. The intensity , open-circuit voltage, short-circuit current of a distance was measured, and the power was calculated ,so the best operating voltage, the most good operating current can be found . we draw curve graph with measured data. In accordance with the curve trend ，we used the least-squares fitting curve functions , and finally summarized the overall dominant functional. The aim is we will be able to get the maximum power operating point in common place after a simple measurement of light intensity, solar panels, open-circuit voltage, short-circuit current . If their relationship can be extended to the actual sunlight, the best resistive load range, and the best operating voltage, current range of the solar cells will be calculated simply . This experiment will provide a basis for simplified load selection of solar cells.
