JR Tokai to Test Next-Generation Solar Cells on Shinkansen Line Noise Barriers

JR Tokai is gearing up to introduce innovative thin solar cells on the noise barriers lining its Tokaido Shinkansen Line tracks, covering a total distance of approximately 650 kilometers. By harnessing the electricity generated from these cutting-edge perovskite solar cells, the railway company aims to power lighting at stations and other infrastructure related to rail operations. To kickstart the initiative, demonstration experiments are set to take place at a research center in Komaki, Aichi Prefecture, in conjunction with other locations, commencing this month.

The perovskite solar cells represent a departure from traditional silicon solar cells as they offer a more lightweight and flexible alternative. JR Tokai envisions installing these advanced solar cells not just on the noise barrier walls but also on diverse surfaces such as walls, windows, and even curved structures along the track. The experimental phase will involve subjecting prototype solar cells to high-speed bullet train vibrations and wind pressures to assess their durability and performance under such conditions. Furthermore, the photovoltaic capabilities of these next-generation solar cells will be evaluated in various outdoor environments to gauge their efficiency and practicality for railway applications.

The Tokaido Shinkansen Line, known for its east-west route connecting Tokyo and Shin-Osaka stations, will potentially see the deployment of solar cells on guide rails mounted on the outer side of south-facing noise barrier walls. JR Tokai plans to monitor and analyze the results of these experiments to determine the feasibility and effectiveness of integrating next-generation solar cells into its rail infrastructure. This initiative marks a significant step towards enhancing energy sustainability within the railway sector and exploring the potential of renewable energy sources for powering essential facilities.
