Money Monster Episode 49
Solar cell, renewable energy for the future

Along with the release of “Renewable Energy 3020” implementation plan by the government, a lot of advanced technologies for new and renewable energy sources have received the limelight. Eco-friendly new and renewable energy sources have replaced coal and oil. And reduction of greenhouse gas emissions has been actively promoted to prevent global warming. Along with the arrival of the fourth industrial revolution, cutting-edge technologies have been applied to the technologies for the new and renewable energy sources. And it has brought about a paradigm shift to the energy industry. Therefore, there's been a growing demand for solar power and a lot of technologies for the commercialization of solar energy have been developed. Perovskite solar cell, which has overcome the limitations of the existing silicon solar cells, is one of the examples. It has a simple production process and higher energy efficiency, so it has emerged as a solar cell for the future. As perovskite solar cell is flexible and light in weight, it is expected to be applied to a lot of different areas. Moreover, along with an increasing number of consumers who put top priority on light weight and convenience, a compact solar-powered charger has been developed. Based on the combination between the flexible CIGS, or Copper Indium Gallium Selenide thin-film solar cell and an LED module, a lot of significant changes have taken place in people's daily lives. We introduce perovskite solar cell, which has paved a new path for the field of new and renewable energy by considering the rapid changes facing the energy industry.

Growth of electric vehicle charging infrastructure

Along with the increasing number of people who use electric vehicles, diversified charging infrastructure has been built to meet the growing demand. The charging stations have become closer to the living radius of users and the charging methods have also become simplified. Users can charge their electric vehicles near their homes if they use a movable electric vehicle charger. Also, it has increased the conveniences of users as they can charge their cars and make a payment at the same time. An electric vehicle charging robot, which has combined artificial intelligence and autonomous driving technologies, has recently been developed. In the past, users had to visit the charging stations. But now, a charging service, which can make a visit to the place where electric vehicles are located, has been newly introduced. Electric vehicle charging robot can approach to electric vehicles based on the autonomous driving technology. And it tries to make a connection with a vehicle. Moreover, it provides enhanced economic effects as dead batteries of electric vehicles are used again. There is a local government which has boosted the development of charging infrastructure for electric vehicles. The electric vehicle charging station operated by Seongdong-gu district produces energy with solar panels and the generated energy is used to charge electric vehicles. As it makes use of eco-friendly energy, it can improve the atmospheric environment and contribute to building a smart city. We look into the electric vehicle charging infrastructure, which has emerged as a promising field along with the growing demand for electric vehicles.

Accelerated exports of the horticultural industry

A lot of horticultural products including colorful flowers and appetizing fruits can give a lot of energy to our lives. Therefore, the horticultural industry has sought remarkable growth by developing diversified varieties and implementing advanced technologies. The field of flowering plants has faced lack of sunshine along with the aggravated fine dust issue. And introduction of artificial lighting has emerged as a solution. The lack of sunshine can be supplemented with artificial lighting. It can make flowers bloom faster and contribute to cultivating high-quality crops. Also, a lot of efforts have been made to extend the lifespan of flowers. The lifespan of flowers can be extended when making preserved flowers by replacing the moisture in flowers with chemical ingredients. The lifespan of preserved flowers can be extended to 3-5 years. Diversified kinds of colorful flowers can be made by maintaining the original texture of natural flowers. Moreover, a lot of new varieties have been developed. In case of grafted cactus, which is a combination of two different varieties, a single type of variety can be raised only for 3-4 years. Therefore, improved varieties which can live longer have been developed and they have been actively exported to overseas countries. We report on the continuing development of the horticultural industry, which has given a boost to the consumption market.
