Abstract A direct normal irradiance calibration method and test bed is established for primary reference cell calibration in Lhasa. The calibration value and uncertainty analysis of direct normal irradiance, spectral mismatch correction, and short-circuit current measurement are discussed and evaluated for photovoltaic metrology calibration reference. The calibration method is based on absolute cavity radiometer which is calibrated against world radiation scale. The calibration result has good accuracy and reproducibility for photovoltaic metrology in China.
