In two separate projects, Japan’s Kyuden Mirai Energy and Nissan Motor are demonstrating the use of flexible, glass-free chalcopyrite PV panels supplied by PXP Corporation.
At Fukuoka International Airport, Kyuden Mirai Energy, the renewable energy subsidiary of Japanese utility Kyushu Electric Power Company, and PXP Corporation, a Japanese startup developing chalcopyrite and perovskite solar technologies, installed glass-free flexible chalcopyrite (CuInSe2) modules on the airport terminal roof.
“The test location is 2 x 6 m and the power is 1.2 kW,” says Hiroki Sugimoto, CTO of PXP Corporation. pv magazineadding that the duration of the project is three months. It is supported by the Perovskite Solar Cell Demonstration Project Grant from Fukuoka Prefecture.
In a separate project supported by the Kanagawa Next-Generation Solar Cell Promotion Project Subsidy, PXP panels were used during a demonstration at a Nissan Motor Corporation car dealership in Totsuka Ward, Yokohama City.
One set of PXP modules, which are typically 0.6mm thick and weigh 0.7kg/m2, are installed indoors in the window area at the entrance to the showroom, and the other set is located on the curved surface of a structural support beam in the portico. The power generated will be used by vending machines, smartphone chargers and an in-store display in the car dealership building.
The demonstration will take place from October 2025 to February 2026. The aim is to assess the location and scope of use of the thin-film solar PV technology, to increase community awareness of the cutting-edge nature of next-generation flexible solar cell technology and Nissan’s environmental efforts, Sugimoto said.
PXP has a growing number of demonstrations of its technology in Japan. Last year, pv magazine reported that Japan’s Softbank Corp. had led a consortium of investors to back PXP in a $10 million round of venture capital.
