Enecoat Technologies Successfully Demonstrates Film-Type Perovskite Solar Cells in Space

Enecoat Technologies Co., Ltd. (Headquarters: Kumiyama-cho, Kuse-gun, Kyoto Prefecture; Representative Director: Naoya Kato) announced that it has successfully conducted an on-orbit demonstration experiment of its film-type perovskite solar cells aboard the "Origami Reflector Array Antenna Demonstration Satellite OrigamiSat-2," in collaboration with Tokyo Institute of Technology (President: Hisataka Ohtake; Headquarters: Meguro-ku, Tokyo), a national university corporation, and the Japan Aerospace Exploration Agency (JAXA) (President: Hiroshi Yamakawa; Headquarters: Chofu, Tokyo). The experiment confirmed power generation in space.

Since 2022, Enecoat Technologies has been jointly researching the space application of film-type perovskite solar cells with JAXA's Space Exploration Innovation Hub. This demonstration utilized the results of that research.

OrigamiSat-2 Mission Progress and Full Success Achievement

Selected as one of the demonstration themes for JAXA's Innovative Satellite Technology Demonstration Program 4, the "Origami Reflector Array Antenna Demonstration Satellite OrigamiSat-2" was launched on April 23, 2026, from New Zealand by Rocket Lab's Electron rocket. Following initial operations, the membrane deployment experiment was successfully completed on May 23, after which the main mission, communication experiments using the deployed antenna, was also successful, achieving full success.

Furthermore, on June 6, 2026, the demonstration experiment for the film-type perovskite solar cells mounted on the satellite's deployed membrane successfully measured IV characteristics (current-voltage characteristics) indicating power generation performance.

Moving forward, we will continue to evaluate the degradation characteristics and performance of film-type perovskite solar cells in the harsh space environment, taking into account and correcting for the effects of varying solar incidence angles and temperature changes unique to orbit.
