    South Korea and Japan in the automotive battery market is fierce competition

    More recently, there is growing concern about world oil market. The international community has been working on efforts to reduce greenhouse gas emissions, while almost all industries are focused on the development of second-generation mobile battery. 
      
    Equipped with mobile battery hybrid electric vehicle (HEV) use of fossil fuels and greenhouse gas emissions can be reduced by 30% or more. The United States and Europe and other developed countries are trying to spread such a future-oriented vehicle. Built-in hybrid electric vehicles (PHEV) and electric vehicle (EV) will be the protagonist of the next generation of hybrid electric vehicles. In the social, economic and environmental aspects of the popularity of these two types of cars is far higher than the average effect of hybrid electric vehicles. So now these two types of vehicles in developed countries is growing at the center of research and development, hoping to achieve commercialization.

    Built-in hybrid electric vehicles: In the park, through the outlet can recharge the car 

    Japan’s Toyota and Honda dominate the hybrid electric vehicles and related technologies. The two companies in the world market share of over 85%. 

    In the hybrid electric vehicles use nickel-metal hydride battery is almost mostly manufactured by Japanese companies. The lithium batteries as a high-profile second-generation mobile batteries, and nickel-metal hydride battery unit volume and unit weight compared to the energy density and a higher output power density. However, due to security, and pricing issues, auto production has not yet to a large-scale use of lithium batteries.

    Toyota Motor Corp. and other Japanese companies announced that from 2008 will be equipped with hybrid electric vehicle batteries. However, due to security issues, lithium cell vehicle market will be delayed. The Hyundai Motor Company announced plans to begin mass production in 2009 will be equipped with lithium battery hybrid electric vehicles. From this, the world’s automotive industry has entered an era of competition lithium battery car. 

    As the car used in the development of mobile battery will take a very long event, so car manufacturers and battery of cooperation between enterprises is of paramount importance. Hyundai Motor and LG Chemical Co., Ltd. have jointly developed co-operation more than five years. In July this year, the upcoming Hyundai Elantra LPG hybrid electric vehicles. In addition, LG Chemical Company has become the U.S. General in the built-in hybrid electric vehicle batteries used in development cooperation partners, the two companies are to proceed with joint development. 

    Today’s world is the era of IT industry and automation, lightweight and easy to carry the commercialization of lithium batteries is in this context arise. In our daily lives as a common automation products such as mobile phones, laptops, PMP, MP3, the lithium battery as an energy source has been widely used. In Korea, LG Chemical and Samsung SDI’s large-scale production beginning in 2000 lithium batteries, with a full 10 years behind compared to Japan. In the original has been monopolized by Japanese companies lithium battery market, Korean companies by virtue of the unique design of lithium battery technology and manufacturing technology has won more competitive. According to projections, last year, South Korean companies in the global market share has reached 30%. 

    As a result, South Korea and Japan to compete in the technical aspects of the present white-hot. Japan from 1992 to 2001 decade, in the storage of electricity used in lithium batteries and small electric cars that use lithium-ion battery development has invested 166 billion yen. From 2002 to 2006, in fuel cell vehicles use lithium-battery development has also invested 53 billion yen.

    This year, the Japanese automakers, battery companies and other related areas of business development with the release of the second-generation mobile automotive battery development program. Since last year, 2011, will be the second-generation vehicle battery systems development, 110 billion yen in R & D goal is to develop a performance 50%, the price is only one-seventh of a new battery. 

    To Hyundai Motor Company and LG Chemical Company as the main force of the Korean companies from 2004 to five years, as a second-generation battery-powered industry, a growing part in the hybrid electric vehicle with a high output power lithium battery development has been invested ₩ 16,000,000,000 budget. In addition, the decision by the Department last year, South Korean knowledge-based economy in 5 years, the built-in hybrid electric vehicles to use the mobile battery and related systems development assistance for ₩ 40,000,000,000, and in 2013 began to mass production.

    At the same time, the current government will pro-environment, car industry, selected as the new pillar industries. Government’s objective is to automobile production in the future in the green area, one of the world’s four major powers. Mobile battery market competition depends on the parts and materials of the core technology development. Although you can use the materials have been commercialized production of hybrid electric vehicles, mobile batteries, but in the production of built-in hybrid electric vehicles and electric car, you must use a higher energy density, better security, new material. 

    Who can first address the issues of these second-generation production problems, anyone can compete in the world battery market opportunities among the occupation.

    Chinese thin-film solar cells will be the “world factory”

    Oerlikon as the world’s first thin-film solar modules to provide Turn-Key services, manufacturers, its thin-film solar cell module using amorphous silicon technology solutions and microcrystalline silicon thin film technology stack, providing conductive glass (TOC) production, PECVD deposition , laser cutting and other critical thin-film cell manufacturing process steps. Oerlikon Solar business unit general manager of Technical Marketing, Sun Haiyan Asia that China has a relative abundance of raw materials (glass) market and talent pool, China’s thin-film solar cells will become the “world factory.” 
      
    SIChina: Do you think Chinese enterprises to enter the thin-film solar PV market, where the starting point? 

    Sun Haiyan: We first of all from the perspective of industry chain to talk about why to enter the thin-film solar cells: First, thin-film solar energy has a cost advantage; Second, the thermal expansion coefficient of less widely used. Again, China has to enter the thin-film solar industry advantage. Because the cost of thin-film solar cell structure, raw material of glass accounts for about 40%, while domestic glass production is the world’s largest, relatively low raw material prices. The same time, domestic enterprises with a rich talent pool, these people including those from the semiconductor, FPD and electronic industries. With the semiconductor and flat panel display industry, compared to thin-film solar cell equipment and funding requirements, relatively low technology threshold, if our goal is 0.7 U.S. dollars per watt, then certainly the middle of a dessert place, the key to see how you do.

    SIChina:: Can analysis

    Thin-film solar cell technology go? 

    Sun Haiyan: thin-film batteries already has 30 years of history, by the transformation efficiency of the restrictions, in the past did not form a large-scale production of thin-film batteries to open up the market. In the past two-junction amorphous silicon thin film solar cell conversion efficiency is only about 5%, plus packaging technology is also problematic, so the cost advantage of thin-film batteries can not be seen. The current industry began to enter the thin-film solar cell mass production phase. Oerlikon now in full swing in 2002 into microcrystalline amorphous plus project, using this technique, after the initial decay after the conversion efficiency is expected to reach 10% or more, at present, we can ensure that clients achieve the 9.3% conversion efficiency. Through the device upgrade process from the amorphous process can be upgraded to increase microcrystalline amorphous process. Thin-film solar cells bottleneck lies in the future: First, how to improve the conversion efficiency; the second is how to improve its manufacturing efficiency, Oerlikon their clients to jointly build a database, for the equipment, the company is concerned, lower TackTime time is very important, that is, reduced production per unit module’s time; The third is to form a scale effect, through the overall control to achieve cost-effectiveness. 

    SIChina:: As the world’s first thin-film solar modules to provide Turn-Key services, manufacturers, do you think of this Turn-Key model of thin-film batteries will give the domestic development of the industry What are the effects? As the manufacturer of the technology mainly depends on the equipment suppliers, will result in customer products have no difference? 

    Hai-Yan Sun: At present, thin-film solar cells rely mainly on process equipment suppliers. The Oerlikon development process through the laboratory, pilot line and then to mass production, we recommend that large customers to buy product also bought the entire line of 1:1 in the test line. 1; 1 pilot online customers increased efficiency in the conversion there is still a lot of space. Can be 1; a pilot test of the success of the process menu transplanted directly into the production line. Thin-film battery has just started a large-scale industrialization, and now has not got to take into account when the product differentiation, each solution has the market for Oerlickon, we are pursuing is not a big size, and the first production line maturity. An important sign is the international certification by TUV and so on. Oerlikon amorphous silicon modules in 2006, has been TUV certified, and more recently the production process through the use of their own TCO module TUV certification, this could make the products to customers quickly enter the market. In addition, the high conversion efficiency is our goal to pursue. The maturity of the existing platform can be upgraded to increase the conversion efficiency of the battery. Process from the amorphous to microcrystalline amorphous plus technology in the future may be added between an amorphous and microcrystalline intermediate layer to increase the degree of light absorption to improve transformation efficiency, the production line can be constantly upgraded with the upgrade process, only have equipment can be subsequently upgraded, so the production line efficiency, reduce the cost. 

    SIChina: Do you think thin-film solar cells with silicon-based solar cells to rival the advent of an era when?

    Sun Haiyan: We estimate the global solar PV market will grow from 2000 to 1 billion U.S. dollars by 2015 expanded to 150 billion U.S. dollars, while the thin-film market share may be increased from 2% to 52%, surpassing crystalline silicon solar cells, become the mainstream.
