摘要
基于差分光谱响应度法搭建了标准太阳电池标定值校准装置,分析了标准太阳电池绝对光谱响应度随电池温度和偏置光辐照度的变化关系,通过数值拟合得到太阳电池短路电流与偏置电流的关系,实现太阳电池标定值测量不确定度1.2%(k=2)。搭建了标准太阳电池标定值户外计量装置,实现测量不确定度2.38%(k=2)。差分光谱响应度法与户外总辐射法测量结果比对的比率值为0.95,表明2种方法测量结果在不确定范围内量值等效。
Based on differential spectral responsivity method, a calibration equipment for reference solar cell is established. The absolute responsivity of reference cell varied with temperature of cell and irradiance intensity of bias light are analyzed. The relationship between the short circuit current and the bias current of the solar cell is obtained by numerical simulation techniques. The uncertainty of the result is 1.2% （k = 2）. Based on outdoor method, a reference cell calibration equipment is established. A detailed uncertainty evaluation of the result is carried out, the value is 2.38% （k = 2）. Through numerical calculation and analysis of the En value （0.95）, it is found that the results measured by the two methods are equivalent.
