Tokaido Shinkansen Line to Utilize Next-Generation Solar Cells
Central Japan Railway Co. (JR Tokai), the operator of the Tokaido Shinkansen Line, is embarking on a project to install next-generation, thin solar cells on noise barriers along its tracks. The electricity generated from these innovative cells will be used to power lighting at stations and other rail-related facilities.
The noise barriers, spanning approximately 650 kilometers of track, will be equipped with perovskite solar cells, jointly developed with Sekisui Chemical Co. These cells offer significant advantages over conventional silicon solar cells, being lighter, more flexible, and adaptable to various surfaces, including walls, windows, and even curved structures.
Demonstration experiments will commence this month at a research center in Komaki, Aichi Prefecture. Prototype solar cells will be subjected to rigorous testing, simulating the vibration and wind pressure experienced during a high-speed bullet train passage. Additionally, their photovoltaic performance will be evaluated in various outdoor environments.
The Tokaido Shinkansen Line, primarily running east-west between Tokyo and Shin-Osaka stations, presents an ideal location for solar cell installation. Plans are underway to mount the cells on guide rails attached to the south-facing side of the noise barriers.
JR Tokai will closely monitor the progress of the experiments and determine the feasibility of large-scale implementation. This initiative holds immense potential for harnessing renewable energy and reducing the environmental impact of the Tokaido Shinkansen Line.
