A 230-meter tall skyscraper in central Tokyo will be the first high-rise in the world to incorporate a large-scale perovskite solar cell (PSC).

The exterior spandrels of the South Tower in the Uchisaiwaicho 1 Chome District Redevelopment will have solar cells generating over 1000kW. The film-type solar panels are under development by Sekisui Chemical. Until recently, installing solar panels on building facades posed several challenges including load and wind-load limitations as well as concerns over future replacement cost. The perovskite solar cells are thin, lightweight, and can also be used on curved surfaces, allowing them to be installed in otherwise difficult locations.

The 46-story skyscraper is due for completion in 2028. In the meantime, Sekisui Chemical is planning to install the same cells on its 12-story headquarters in Osaka by 2025, in what will be the first permanent installation of these film-type panels on a building in Japan.
