At 7:00 PM Beijing Time on March 30, 2026, the Lijian-2 Yao-1 carrier rocket blasted off successfully from the Dongfeng Commercial Space Innovation Test Zone, precisely delivering the Qingzhou prototype test spacecraft and other payloads into their designated orbits. On this significant occasion, the high-efficiency ultra-thin flexible silicon heterojunction solar cells, independently developed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences, embarked on their space journey aboard the Qingzhou spacecraft, officially initiating their space applications to power the spacecraft. These solar cells were collaboratively developed by the New Energy Technology Center of the Shanghai Institute of Microsystem and Information Technology and Liuzhitao New Energy. Designed to meet the demands of commercial spaceflight, they incorporate high-quality monocrystalline silicon wafers and have undergone numerous iterations and refinements. By leveraging unique technologies, these cells demonstrate exceptional flexibility, vibration resistance, and shatterproof properties.
