GB/T 6492-2025Aerospace reference photovoltaic cells (English PDF)

1 Scope

This document specifies the requirements for standard photovoltaic cells used in aerospace, screening test methods, calibration and transfer, maintenance, storage and transportation requirements.

This document applies to standard photovoltaic cells made of monocrystalline silicon, single-junction gallium arsenide, and multi-junction gallium arsenide for aerospace applications, and is intended for testing aerospace photovoltaic cells.

When testing individual cells, modules, composite panels, or arrays, calibrate or determine the total irradiance established by the test light source on the surface of the photovoltaic cell under test.

3 Terms and Definitions

The terms and definitions defined in GB/T 2297 and the following terms and definitions apply to this document.

4 Naming Method for Standard Photovoltaic Cells

Standard photovoltaic cells of grades I and II should be labeled with their naming number in an appropriate location according to Table 1, indicating the cell's grade and type.

And numbering, etc. Standard photovoltaic cells generally only provide the cell number; refer to Part 4 of Table 1 for the numbering method.
