[SMM PV Flash] German Solar-and-Storage Firm BSH Files for Insolvency

Major PV module markets remained divided by region and product segment this week.

According to Yanhe Technology’s official WeChat account, on September 17, China successfully launched the Tianyi-51 and Tianyi-52 satellites from the Jiuquan Satellite Launch Center using the Kuaizhou-11 Y3 carrier rocket. The satellites smoothly entered their designated orbits, and the launch mission was a complete success. Yanhe Technology’s independently developed flexible perovskite PV module entered the designated orbit along with the Tianyi-52 satellite, officially initiating long-term on-orbit performance monitoring and space-environment adaptability verification. This marks the first time in China’s commercial aerospace sector that an engineering-grade, full-operating-condition, module-level on-orbit verification of flexible perovskite has been carried out, signifying that China’s flexible perovskite space PV technology has formally advanced from the laboratory research stage to the engineering application verification stage. This launch precisely delivered the Tianyi-51 and Tianyi-52 satellites into their designated orbits in a “one rocket, two satellites” configuration. As a cutting-edge technology demonstration payload, the Yanhe flexible perovskite module will, on orbit, be subjected to extreme space operating conditions involving the coupling of multiple factors, including high vacuum, ±100°C thermal cycling, high-energy EVA irradiation, and low-Earth-orbit atomic oxygen erosion. The evaluation will focus on electrical output characteristics under thermal-cycle fatigue, irradiation degradation, and mechanical vibration conditions, as well as interconnection reliability and mechanical stability, with core performance parameters transmitted back in real time via the satellite’s telemetry system.

On September 16, the groundbreaking ceremony for the Ximazi sub-project of the Huaneng Yushe 1 million kW wind and solar power base was held at the project construction site in Xima Township, Yushe County. Lu Chenzheng, Deputy Secretary of the Yushe County Party Committee and Head of the United Front Work Department, and Yang Shuting, Executive Director, Party Secretary, and General Manager of Huaneng Shanxi Energy Service Co., Ltd. (referred to as the Energy Service Company), attended the project groundbreaking ceremony.
