Abstract

The invention belongs to the field of new energy sources and space power supply-solar photovoltaic application and particularly discloses a GaAs / Ge single-junction gallium arsenide solar cell array which works under a space solar synchronous orbit. Through the photovoltaic characteristic of an efficient GaAs / Ge solar cell, light energy can be converted into electric energy during a light period, so that stable and efficient electric energy can be provided for a load; the solar cell array consists of a left wing, a right wing, six solar panels and 12,988 GaAs / Ge single-junction gallium arsenide solar cell plates; and constitution units mainly comprise a substrate, a laminated GaAs / Ge solar cell, a connecting piece, a power transmission circuit and the like. The GaAs / Ge single-junction gallium arsenide solar cell array has the characteristics of high efficiency, low temperature coefficient, high radiation resistance and high reliability, can adapt to radiation and charging environments of a low earth orbit (LEO) particle radiation region and a high-energy low-density plasma region and is fully suitable for working conditions of high temperature alternative frequency of the solar synchronous orbit.

Description

technical field [0001] The invention belongs to the application field of new energy and space power supply-solar photovoltaic, and in particular relates to a GaAs / Ge single-junction gallium arsenide solar battery array working in a space sun-synchronous orbit. Background technique [0002] GaAs / Ge single-junction gallium arsenide solar cell array is a photovoltaic power supply device using GaAs / Ge single-junction gallium arsenide solar cells. Gallium arsenide solar cell is a III-V compound semiconductor solar cell, which has high electron mobility and light absorption coefficient. After depositing a "window layer" on the surface of the P-N junction, the surface recombination loss is greatly reduced, so that It has become one of the solar cells with the highest photoelectric conversion efficiency at present. At present, there is still a big gap between my country's domestic single-junction GaAs solar cell array technology and the international level. The mass production eff...
