Tokyu
Advanced demonstration experiment of perovskite solar cells will be conducted at Aobadai Station on the Tokyu Den-en-toshi Line
– Japan’s first demonstration experiment in a public space called a station! ~ Lectures by Project Professor Miyasaka of Toin University of Yokohama will be held at the Zero Carbon Festa held on the same day ~

Toin Gakuen (hereinafter referred to as Toin Gakuen), Tokyu
Corporation (hereinafter referred to as Tokyu), Tokyu Corporation (hereinafter referred to as Tokyu Corporation), and Yokohama City will be held on Saturday, February 11, 2023. , A preliminary demonstration experiment (hereinafter, this experiment) of perovskite solar cells (hereinafter, the same battery) will be conducted in the free passage in front of the front ticket gate of Aobadai Station on the Tokyu Den-en-toshi Line. This experiment is Japan’s first* initiative in which the same battery, which is being developed for
commercialization, will be tested in a public space such as a station in a way that the general public can feel familiar. (* Surveyed by 4 companies)
In addition, this experiment is based on the agreement on mutual cooperation in “education” and “energy” concluded by Toin Gakuen, Tokyu, and Tokyu Corporation as part of the “nexus concept”, as well as Yokohama City and Toin Gakuen It will be an initiative based on the “Agreement on Building a Decarbonized Society and Promoting
Sustainable and Attractive Lifestyles” signed by the two parties. In this experiment, a large area (703 cm²) made by Toshiba Corporation was used to demonstrate indoor power generation, which is a feature of the battery, under the skylight of the free passage in front of the ticket gate at the front entrance of Aobadai Station, which is used by local people on a daily basis. ) with the cooperation of Toshiba Energy Systems & Solutions Corporation. Through this experiment, we will confirm the performance of the battery and use it to consider future utilization methods such as installing the battery in assets owned by each party (existing buildings, stations, rolling stock, elevated bridges, etc.).
In addition, Toin Yokohama University Laboratory will participate in the “Zero Carbon Festa starting from Den-en-toshi”, a promotional event aimed at realizing a decarbonized society as part of urban development, which will be held on the same day at Splus Aobadai, which is located a 3-minute walk from Aobadai Station. By using the same research battery (hereafter referred to as research material) produced in , we will create an opportunity for local people to touch and understand the battery up close.
We will create a place where you can experience the characteristics of the battery, such as turning a propeller with the generated
electricity and moving a model train (N gauge). Professor Tsutomu Miyasaka will give a lecture on the future potential of the battery. Furthermore, in the future, we will create opportunities for many people to come into contact with the battery and strive to spread the future image of the battery that the battery will bring.

■ What is a perovskite solar cell?
Solar cells, which directly convert the sun’s light energy into electricity, are the most widespread renewable energy sources. Currently mass-produced solar cells are silicon solar cells, which are widely used in mega-solar power plants. increase. Therefore, there is a demand for the development of new solar cells that are thin, lightweight, and capable of generating power in various light environments.
The “perovskite solar cell” developed by Katsutomu Miyasaka, specially appointed professor at Toin University of Yokohama, is expected to be the next generation solar cell. This is a new type of solar cell that uses a material with a crystalline structure called perovskite, and the latest data* from the National Renewable Energy Laboratory in the United States reports a high conversion efficiency (25.7%) comparable to that of silicon solar cells. It has been.

・Characteristics of perovskite solar cells compared to silicon solar cells Perovskite films are manufactured by printing technologies such as spin coating and inkjet, so they can be manufactured at a lower cost than existing solar cells. In addition, flexible and lightweight solar cells can be realized, making it possible to install silicon solar cells on curved surfaces and vertical surfaces of buildings, which is difficult for silicon solar cells. Therefore, it is expected that the introduction of solar cells in urban areas where land is scarce will gain momentum. Furthermore, unlike silicon solar cells, it is possible to generate power even in cloudy or rainy weather, and even under weak light such as indoor light. Therefore, it is expected to contribute greatly to energy saving by introducing it to various environmental sensors and IoT devices used indoors.

・Professor Tsutomu Miyasaka, Toin University of Yokohama, invented perovskite solar cells and continues to lead research and development In 2009, he published the world’s first paper on perovskite solar cells. Since then, we have continued to lead the development of new materials and manufacturing methods for the same solar cells. In particular, he is famous for his research on plastic film-type photovoltaic elements, which are lightweight and flexible. In joint research with JAXA, we are conducting durability evaluations and demonstration experiments of lightweight thin-film perovskite solar cells for stratospheric balloons and space satellites. Taking advantage of the high efficiency of indoor power generation, which is a feature of the solar cell, research is underway with the aim of applying it as a power generation element for IoT.

■ What is the “nexus concept”?
The nexus concept is a consumer-oriented urban development in suburban areas that Tokyu and Sigmaxis Group are working on. In this concept, “agriculture and food,” “wellness,” “mobility,” “energy,” “resource recycling,” and “education” are set as sustainable themes, and through collaboration with companies and governments, demonstration
experiments will be conducted for the social implementation of various services. is working on We will promote the evolution into a “town that makes people want to walk” where people can work, live, play, and study in close proximity by building a system for mutual assistance through demonstration experiments and forming a recycling-oriented community.
