Shenzhou-23 Embarks on a Historic Mission! Perovskite Solar Cells Undergo First Major In-Orbit Test at China’s Space Station

On May 24th, the Shenzhou-23 manned spacecraft lifted off successfully for China’s Space Station, carrying nine cutting-edge scientific experiments. Among them, the dynamic in-orbit service test of perovskite solar cells officially commenced—marking the first-ever in-space measurement of perovskite cells at China’s Space Station. This milestone signifies a critical step forward in the industrialization of next-generation space photovoltaic technology.

The in-orbit experiment features two core cell devices: single-junction perovskite cells and perovskite-based tandem cells. These devices will withstand extreme space conditions, including intense ultraviolet radiation, high-energy particle bombardment, atomic oxygen corrosion, and drastic temperature fluctuations. By measuring real-time conversion efficiency degradation data, the experiment aims to unravel material performance evolution and failure mechanisms, laying a solid technical foundation for energy systems in future low-Earth orbit satellites, deep space exploration missions, and lunar bases.

As the third-generation core photovoltaic technology, perovskite solar cells stand out as the preferred solution for space photovoltaics and deep space energy applications, boasting exceptional advantages such as high power-to-weight ratio, lightweight flexibility, low cost, and superior photoelectric conversion efficiency. However, the harsh and complex space environment remains the biggest barrier to the large-scale aerospace application of perovskite cells. High-precision, highly reliable professional testing is an indispensable prerequisite for technology commercialization.
