General specification for space solar cells
1 Scope
This document specifies the requirements, test methods, inspection rules, packaging, transportation and storage of solar cells used in space:
This document applies to unpackaged monocrystalline silicon solar cells, rigid substrate gallium arsenide solar cells and flexible substrate gallium arsenide solar cells for space
Battery:
2 Normative references
The contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them, dated references
For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to
this document:
GB/T 2296 Solar cell model nomenclature
GB/T 2297 Solar Photovoltaic Energy System Terminology
GB/T 6494 Test method for electrical performance of aerospace solar cells
GB/T 6496 Calibration method of solar cells for aerospace
3 Terms and Definitions
The following terms and definitions defined in GB/T 2297 apply to this document:
3:1
chip chip
Partial loss of cell body material along the edges or corners of the solar cell, but not through the full thickness of the cell:
3:2
nick nicks
The solar cell is partially missing along the edge or corner of the cell body material, which has penetrated the entire thickness of the cell:
3:3
blank voids
Any blank spot with a diameter greater than 0:13mm and no coating material (such as electrode metal layer or anti-reflection film):
3:4
electrode metal contact
The surface of the solar cell forms an ohmic contact and acts as a conductor that collects photogenerated carriers and draws out current:
Note: The electrodes of solar cells are divided into positive and negative electrodes: The light-receiving surface electrode is usually called the upper electrode, and the non-light-receiving surface electrode is called the lower electrode:
3:5
Package cover
The upper surface of the single solar cell is covered with a light-transmitting material for protection:
Note: Monocrystalline silicon solar cells and gallium arsenide solar cells on rigid substrates are generally packaged with glass cover sheets: Flexible substrate Gallium arsenide solar cells generally use flexible
Encapsulate with light-transmitting material or glass cover:
