Guangdong Mellow Energy has announced that its self-developed 30×30 cm² ultra‑flexible perovskite photovoltaic module has achieved a TÜV NORD‑certified power conversion efficiency of 21.79%. The company says this places the device among the most efficient flexible perovskite modules of its size worldwide, and highlights that the module also reaches an industry‑leading power‑to‑mass ratio of 26 W/g, outperforming most mainstream thin‑film PV technologies.
Mellow Energy notes that this combination of high efficiency and extreme lightweight design is aimed specifically at aerospace and satellite applications, where every gram of payload has a direct impact on launch cost and available capacity. In current commercial satellite constellations and future large orbital infrastructure, the power‑to‑mass ratio is a core benchmark for space power systems, as higher power output per unit weight allows operators to install more equipment, extend mission lifetimes and reduce launch expenses.
According to the company, rapidly expanding commercial satellite networks are driving demand for reliable, scalable space power solutions, but conventional rigid PV hardware struggles to support frequent, large‑scale deployment due to weight penalties, complex deployment structures and barriers to cost‑effective mass production. By contrast, flexible perovskite modules can better meet sector requirements thanks to their high efficiency, low weight, foldable design and compatibility with roll‑to‑roll manufacturing techniques, which promise lower production costs and new models for supplying power in space.
Mellow Energy adds that the new module is expected to support domestic commercial aerospace projects and future deep space missions by enabling large orbital infrastructure to be more energy self‑sufficient. However, the company stresses that all components intended for space use must pass rigorous reliability assessments: beyond laboratory and ground tests, the flexible modules will need full system verification, radiation testing and extended in‑orbit operational trials before they can be formally deployed.
