Abstract:
Three different types of radiometry have been examined to find the best type for solar spectral irradiance measurements requiring long-term (22 years) and ultra-high precision (0.1% uncertainty) in the near-UV, visible, and near infrared. It has been determined that the best radiometry uses the self-calibration technique developed at NBS using laser lines. Normalization techniques were applied to silicon reflectivity and quantum efficiency models for use with thermal sources and grating spectrometers. The results compared with similar laser-source calibration showed disagreement less than 0.1%. Germanium and GaAsP detectors were also investigated in the infrared and deep blue wavelengths. The germanium detector showed significant recombination loss of photogenerated carriers due to the ion implantation fabrication process. GaAsP detectors have very small dark currents ( < 1 nA), but also demonstrate significant recombination losses inside the photodiode. The possible loss mechanism of the Ge and GaAsP detectors are suggested for future study.
