Abstract: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.
