ICS 27.160 CCSK83 National Standards of the People's Republic of China Replaces GB/T 6492-1986 Standard photovoltaic cells for aerospace Published on 2025-12-31 Implemented on July 1, 2026 State Administration for Market Regulation The State Administration for Standardization issued a statement.

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 6492-1986 "Standard Solar Cells for Aerospace Use". Compared with GB/T 6492-1986, the main differences are structural adjustments and... Aside from editorial changes, the main technical changes are as follows. ---A "Scope" section has been added, expanding the standard's provisions and scope of application (see Chapter 1); ---The section on "Variety, Grade, and Parameters" has been revised, and terms and definitions have been added (see Chapter 3, Chapter 1 of the 1986 edition); ---The naming convention has been changed, and naming information for triple-junction and multi-junction photovoltaic cells has been added (see Chapter 3, Chapter 1 of the 1986 edition); ---The "Technical Requirements" section has been revised, and the requirements for solar cell size have been removed (see Chapter 5, Chapter 2 of the 1986 edition); ---The sample screening and standard screening were combined, and the test methods and equipment requirements were changed (see Chapter 6, Chapter 3 of the 1986 edition); ---The section on "Transmission of Standard Solar Cells" has been revised to include content on the transmission of sunlight under ground level (see Chapter 7, Chapter 4 of the 1986 edition); ---The "Parameters" content is merged and unified with Appendix C to standardize the parameter requirements for standard photovoltaic cells (see Appendix C, 1986 edition). Chapter 1). Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents. This document was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

Hu Tao, Wang Jinyu, Zhang Ning, Xiao Zhibin, Tie Jianrui, Meng Haifeng, Wang Ganqiang, Zhuang Tianqi, and Wu Zhenlong. The release history of this document and the document it replaces is as follows. ---First published in 1986 as GB/T 6492-1986; ---This is the first revision. Standard photovoltaic cells for aerospace

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.
