PVTIME – Guangdong Mellow Energy Co., Ltd. has obtained TÜV NORD certification for its 30×30 cm² ultra-flexible perovskite photovoltaic module, developed in-house, which achieves a power conversion efficiency of 21.79%. This result places the product among the most efficient devices of its size globally. It also has an industry-leading power-to-mass ratio of 26 W/g, outperforming most mainstream thin-film photovoltaic technologies.
Within the aerospace sector, weight directly governs launch expenditure, with every additional gram of payload restricting available operational space and raising transport costs. As there are limited opportunities for in-orbit servicing, the power-to-mass ratio is the core benchmark for space power systems. Higher power output per unit weight enables satellite operators to install more equipment, extend service life, and reduce launch costs, which is the main benefit of the firm’s latest technical advance.
The expansion of commercial satellite networks has created a rapidly growing demand for reliable space power solutions. However, conventional rigid photovoltaic hardware cannot easily support frequent, large-scale satellite deployment programmes due to the high costs associated with weight, complex deployment structures, and barriers to mass production. In contrast, flexible perovskite modules meet the sector’s requirements thanks to their high efficiency, low weight, foldable design, and compatibility with roll-to-roll manufacturing techniques, which can reduce production costs and transform space power supply models. This technology will support domestic commercial aerospace and deep space missions by enabling future large orbital infrastructure to be energy self-sufficient.
All components intended for use in space must pass rigorous reliability assessments. Results from laboratory and ground tests alone are not sufficient for deployment in the aerospace industry, and these flexible modules will need to undergo full system verification, radiation testing and extended in-orbit operational trials before they can be rolled out formally.
This latest technical milestone addresses the industry’s growing need for lightweight power supplies to support expanding satellite fleets and large-scale space infrastructure. Mellow Energy will continue to research and develop flexible perovskite photovoltaic technology, expanding its application across the terrestrial and aerospace sectors in order to realise the full potential of this innovative energy solution.
