Introduction

Interpretation of the core content of the standard

GB/T 6496-2017, as the core standard in my country's aerospace photovoltaic field, systematically stipulates the calibration methods for solar cells such as monocrystalline silicon and gallium arsenide. Compared with the 1986 edition, the main technical evolution is reflected in:

New calibration requirements for multi-junction GaAs sub-cells
Introduction of high-altitude aircraft/balloon calibration method (Appendix A)
Adoption of AM0 spectral data updated by ISO 15387:2005

Comparison of calibration principle systems

Absolute direct radiometer: error ≤0.2%

Spectroradiometer wavelength range: 280-2500nm

Sun tracker tracking accuracy: ≤0.5°

Environmental control requirements

Calibration must meet the following requirements:

Irradiance＞750W/m²

Air quality 1.0-2.0

Current fluctuation within 30s ≤0.5%

Implementation suggestions

Operation process optimization

Preferentially use temperature control device to maintain 25±1℃

Repeat the test at least 5 times a day

Average of 3 groups of data on different dates

Uncertainty control

Main error sources:

Absolute irradiance measurement error

Spectral mismatch correction error

Temperature control deviation

Technology development prospects

International trend shows:

Space station calibration will become a new direction

Demand for multi-junction battery calibration increases

Spectral response test accuracy requirements increase
