TOKYO — From the Crystal Palace at London 1851, the telephone at Philadelphia 1876 to the escalator at Paris 1900, the World Expo has always showcased innovations and cutting-edge technologies of the time. At the ongoing Expo 2025 Osaka, host country Japan is promoting its latest technology at an unlikely spot; the bus terminal outside the main venue.
When visitors arrive at the Yumeshima Transportation Terminal 1, they will see more than 250 panels of ultrathin, lightweight “perovskite” solar cells forming the curved roof of the 250-meter-long terminal. These film-like solar panels, Japan hopes, will be the killer technology that not only grants the country more renewable power and reduces its dependency on China, but also gives it the chance to be the leader in the next generation of solar battery technology.
