Japan-based Mitsubishi Electric Corporation was selected by JAXA as a representative organization under the first phase of the Space Strategy Fund. The contract involves developing domestic solar cells, cover glass, and solar arrays to strengthen Japan’s satellite supply chain. Rising demand for low earth orbit constellations has increased the requirement for radiation-resistant solar cells and cover glass, causing shortages. Mitsubishi Electric will work with domestic suppliers to produce low-cost solar cells and evaluate glass used in ground applications for space. Mitsubishi Electric will also design new solar arrays that incorporate these elements to lower costs and secure stable supply. In solar cell research, Mitsubishi Electric will partner with PXP Corporation, which develops next-generation photovoltaic conversion elements. The collaboration focuses on perovskite/CIGS tandem solar cells that combine both materials to maintain efficiency and resist radiation. Perovskite and CIGS enable simpler, cheaper, and larger-scale manufacturing compared with current III-V solar cells used in satellites. This project aims to support reliable satellite component availability within Japan.
