YOKOHAMA -- The city government and a local university here have agreed to work toward the real-world use of flexible, film-like Perovskite solar cells that could even be used on clothing, amid global competition to put the technology into practice. The thin, lightweight cells were developed by Toin University of Yokohama, and are being hailed both within Japan and internationally as an "ace" for boosting renewable energy. Tsutomu Miyasaka, a specially appointed professor at the university, enthused, "With the city's help スーパーコピー服  we hope to make these solar cells from Yokohama a reality." What separates the cutting-edge Perovskite solar cells from their predominant silicon cousins is their low production cost and that they can be installed on curved surfaces, such as cars or building walls. They can also generate power even in dim light ブランドコピー  such as inside rooms or on cloudy days.

Miyasaka and other researchers published the world's first thesis on the cells in 2009. Around 30,000 people are studying the technology worldwide, and competition is heating up to put them into practical use. Miyasaka is considered a strong contender for Nobel prizes in both physics and chemistry. However 時計コピー  there remain challenges to consider before the technology can enter widespread use, such as durability and the amount of power it generates when installed. The Yokohama Municipal Government and the university signed a partnership agreement on Feb. 9, and conducted a demonstration two days later at the Tokyu Den-en-toshi Line's Aobadai Station by installing 700 square centimeters of Perovskite cells at a site with little direct sunlight, on a passage in front of the ticket gate. The energy generated by the cells powered a model train and made a propeller spin. By installing them in a common place, the city aimed to improve public understanding of the technology. There is also talk of future plans to install the cells experimentally on surfaces including greenhouse walls and children's backpacks. At a Feb. 9 press conference, Miyasaka remarked, "(The cells) can be also installed on outdoor tents, cars, and clothing. Using this (technology), I hope the entire town becomes a solar power plant."
