Study the temperature effect of mono-crystalline silicon solar cell performance via the model and experimental

周围环境温度是太阳能电池进行能量高效转换最重要的影响因素.本文利用理论模型预测单晶硅太阳能电池各性能参数的温度效应,并通过实验测量单晶硅太阳能电池在不同工作温度下的J-V特性曲线,得出短路电流密度(Jsc)、开路电压(Voc)、填充因子(FF)和效率(η)等参数值.利用不同温度下各参数值的变化关系,找出温度波动对各参数的影响规律.研究发现,实验测量结果与理论计算值一致,短路电流密度随温度升高会出现微弱增加,但开路电压、填充因子和效率都随温度升高而降低,为太阳能电池的高效工作提供了有利的参考.

Ambient temperature is the most important factor for the efficient conversion of solar cells .This paper predict the temperature effect on mono-crystalline silicon solar cell performance parameters by theoretical models,and obtain the J-V characteristic curve of mono-crystalline silicon solar cell under different temperature through experimental measurements ,it can be get the performance parameters for mono-crystalline silicon solar cell under different temperature,such as short-circuit current density （Jsc）,open circuit voltage （Voc）,fill factor （ FF） and efficiency （η） .Based on the relation between the variation of parameter values and different temperatures ,it found out the influence of temperature fluctuation on each parameter .Found that the value of ex-perimental measurements agree with the theoretical predictions ,the short-circuit current density increase weakly with the temperature rise , but the open circuit voltage , filling factor and efficiency decrease with temperature increase ,and provided a beneficial reference for solar cell operation .
