New Flexible Monocrystalline Silicon Battery to Support Commercial Aerospace and Space Solar Development

According to CCTV News, on May 11, the Tianzhou-10 spacecraft carried samples of flexible packaged monocrystalline silicon solar cells into space to conduct on-orbit space environment experiments. This experiment project will provide technical support for China’s commercial aerospace internet networking, space computing power, and the development of future space solar industry.

The flexible monocrystalline silicon solar cells sent into space along with Tianzhou-10 were independently developed by China’s research team over three years. After researchers packaged the battery prototype samples, they were placed into a dedicated experimental unit and sent to space. The samples will be installed on the external exposure experimental platform of the China Space Station’s Materials Module to conduct exposure experiments under comprehensive extreme space environments. It is understood that, compared with the current mainstream gallium arsenide batteries used in aerospace, this flexible monocrystalline silicon battery is lightweight, thin, rollable, and has controllable weight; with less than one kilogram per square meter, its transportation and launch costs are lower, and its production cost is only one-tenth that of gallium arsenide batteries.
