Anputai raises Series B for space-grade perovskite tandem cells as production line nears launch
What's the deal? Shanghai Anputai New Energy, a developer of space-grade perovskite-silicon tandem solar cells, has raised a Series B round of tens of millions of yuan, the company announced on November 9, 2026. Songjiang State-owned Investment, Shanghai Rongtai Fund, and Bozheng Capital joined as new shareholders.
Why now? The funding lands as Anputai readies its 20MW production line in Songjiang, Shanghai. The company says the main equipment has arrived, the plant is nearing completion, and it expects its first batch of cells by the end of November.
What's the endgame? A 2023 spin-off of Nanjing University of Aeronautics and Astronautics, Anputai makes perovskite-silicon tandem cells for commercial satellites. It has worked with the Shanghai Institute of Space Power-Sources since late 2023, building a joint lab.
The track record: Samples have passed electron irradiation, thermal shock, and reverse-bias tests, and the company plans further verification across particle radiation, UV exposure, temperature cycling, and vacuum cycling. No efficiency or lifetime figures have been disclosed. In July 2026, Anputai raised a Series A of nearly US$13.8M, led by Shanghai Kechuang Intellectual Property.
What could go wrong? The technical case for space-grade perovskite is promising but unproven: researchers have reported tandem cells with 27.49% certified efficiency under space-like illumination, yet that is not the same as proven long-term performance in orbit. Anputai's significance depends on whether it can show credible testing or flight milestones.
The signal: Space-grade perovskite is becoming a small but visible funding trend. South Korea's Flexell Space raised $20 million in July for flexible perovskite/CIGS cells, and China's Xingyi Core Energy raised about $14 million in September for space testing. Anputai's round fits a broader push to turn lightweight, high-efficiency cells into deployable space power.
