Polaris solar PV net news: recently, this reporter visited the Hina Group located in the United States subsidiary Alta Devices workshop in Silicon Valley. Inside the rows of high-tech equipment at full throttle operation, Chinese scientists have marveled at the great idea lets reporters, they wanted to use wearable equipment, automobile and other thin-film technology the subject of each individual as a power, so that the energy is everywhere.
Top technology boost industrial upgrading
For more than 30 years reform and opening up, the low cost of labor and natural resources, environment is a key driver of China’s rapid economic development. As China’s international comparative advantage is disappearing, rising labor costs, resources and environment bearing down, the traditional model of development is unsustainable.
From transition to innovative advantage is the low cost advantage supported China, inevitable choice for the development of the world’s second-largest economy, but also the future of China’s economic development needs of the new normal. But the reality is that many of China’s industries in the global value chain, key technologies are controlled by others, products low profit. Lack of core technologies become the bottleneck of China’s industrial upgrading.
For example in the solar photovoltaic industry, in our country, the positioning of the photovoltaic industry is “strategic industries”, the so-called “emerging” is has great room for development in the future, and “strategic” represents its overall and long-term interests. However, PV industry in China face the problem of insufficient core competence, despite the current PV cell production world production of about 60%, but advanced technologies, materials and high-end equipment still relies on imports, especially high-end equipment imports push up costs, “kidnapped” technological innovation.
Throughout the PV industry, since 1883, United States inventor Charles ˙ Fritz first successful preparation of solar photovoltaic cells, in recent decades, technology has three generations of solar cells. First on behalf of polycrystalline silicon, monocrystalline silicon solar cell, second on behalf of amorphous silicon thin film solar cells and high efficiency, low cost, large scale Copper-Indium-Gallium-selenium thin-film batteries, high performance flexible gallium arsenide cells, chromium batteries such as Telluride, the third generation of mainly refers to the organic and dye-sensitized cells and other emerging battery technologies. Related research displayed, Silicon, and polysilicon and film in application Shang each with pros and cons, but due to film battery, especially Copper Indium Gallium se battery, and arsenic of gallium has better of weak light power sex, and high temperature power sex (temperature improve Shi, battery effectiveness declined smaller), so in actual electricity Shang, film battery of advantage more highlight, also, film battery due to its quality light, and color can adjustable, and shape can plastic, features, can widely application Yu electronic products, and can wear equipment, and car, civilian solar field.
Chairman of hanergy holdings group said Li Hejun, Hina is by promoting photovoltaic power generation technology of the world’s top film industry upgrading, China ahead. Hina one after another in the past two years, the world leader in thin-film solar companies Germany Solibro, United States MiaSol é, GlobalSolarEnergy, and AltaDevices into their folds, electricity is Hina’s film technology has reached the international advanced level, with Copper-Indium-Gallium-selenium cells to get United States national renewable energy laboratory (NREL) certification the highest conversion rate of 20.5%. Gallium arsenide cells highest conversion rate is 30.8%, which is thin-film solar cell world record for the highest rate of technology transfer, which allows Chinese to become world solar photovoltaic field can not be shaken technology leaders.
Mobile energy, and energy will be ubiquitous
Who represents not only the world’s top film power generation technology advances in solar technology, also a no less than the Internet, mankind, ultimate game as much as the Internet revolution of human energy use, it revolutionized the traditional way to use energy, thus making human industrialization process reengineering. Thin film application generation techniques will bring power and transmission of innovation. China is now developing distributed generation, thin-film technology integrated into building solar power products, its near the electricity demand and generation, and thousands of roofs interconnect. Centralized power supply system relies on large power plant currently in use at hundreds of kilometres or even thousands of kilometres of electricity transmission problems for waste and inefficiency in. New smart grid is significantly different, it helps eliminate pollution, to cut costs and increase reliability.
In addition made it possible for distributed power system, films new forms of power generation technology also led the development of mobile energy, consumers no matter where you go you can bring the power around. Mobile energy is based on portable distributed generation technologies, energy storage, control, information and communication technology combination, removable, all weather, energy-efficient supply. Mobile energy: the revolution of energy use, is to use thin-film power where and when energy, energy is everywhere. Mobile energy will be turned on its head the way humans use energy.
The spread of portable electronic devices on the Internet becomes an essential part of people’s lives, while conventional fossil energy reserves shrinking and the increasing environmental pressure, electric vehicle industry will be substantial development opportunities, follow is the huge demand for mobile energy supply. Characteristic of a portable, intelligent, networked thin-film solar power generation technology will provide best solution for mobile energy, and bring new energy, new energy vehicles, high-end equipment manufacturing, new materials, energy saving and environmental protection strategies, such as the development of emerging industries to form a “new normal” under China’s new economic growth.
