1. Triple-Junction GaAs Solar Cells:

At the heart of Shanghai YiM’s offerings are Triple-Junction Gallium Arsenide (GaAs) Solar Cells, which are specifically designed to operate efficiently in the extreme conditions of space. These high-performance cells are qualified for use in both Low-Earth Orbit (LEO) and Geostationary Orbit (GEO) satellites, in compliance with the stringent ECSS E ST20-08C standard. This makes them ideal for powering long-duration space missions.

2. GaAs Solar Cells Successful Applications:

Triple-Junction GaAs solar cells have been successfully deployed in numerous space missions, where they have shown exceptional performance. Some of the key missions that have used these advanced solar cells include:

Ø Remote Sensing-32

Ø Mozi

Ø Ocean-2B

Ø Beidou-42

Ø Piaochong-5

Ø Chang’e-4

Ø Wangtong-1

Ø Beidou-3 (M12)

Ø Gaofen-11 (02)

Ø ZY-3 (03)

Ø NH-1

Ø TT-5

Gallium Arsenide (GaAs) solar cells are known for their high efficiency, lightweight, and resilience in harsh environments, making them an excellent choice for a wide range of applications, including bird-related technologies. While the use of solar power for birds is not a widely discussed topic, there are a few emerging areas where GaAs microcells could have practical applications.

These successful applications mark a significant milestone in China’s space program, where the advanced technology of in-orbit power subsystems has been demonstrated on multiple space vehicles. The use of Triple-Junction GaAs solar cells in these missions has set a new precedent for China’s space industry, ensuring reliable and efficient power generation in challenging space environments.

By providing innovative power solutions for space exploration, Shanghai YIM Space Power Co., Ltd. plays a key role in supporting China’s ambitious space programs, while also contributing to the development of new energy technologies on Earth.
