OFweek solar photovoltaic network news: Yunnan Shilin, most people hear the word of the first reaction: This is one of the famous scenic spots. In fact, this is just a definition of it, in the network simple search, in addition to the "Yunnan Stone Forest Scenic Area" in this sense, "Shilin County in Yunnan province also ran out. Scenic area of the famous natural needless to say, "the only thing in the world is located in the subtropical plateau area of Karst Landform Scenic Area", "the best in all the land wonders" describe enough to make it famous, as the names of the stone forest, have also focused attention.
People familiar with the domestic photovoltaic industry will know the largest stone forest is located in Yunnan 1 MW solar power grid, in July 2012 by the Beijing Sanglin Lantian Automation Technology Co. Ltd. was put into production. It focus on photovoltaic industry attention, because the film station is CIGS technology, is Chinese solar energy in the field of CIGS film's first demonstration project, it is a major breakthrough in commercial use of CIGS thin film solar cell. According to the monitoring data and power plant operators, operating since the product performance is good, the most critical parameter is the product while the cost and conversion rate than the polycrystalline silicon solar cell slice, but due to weak light and strong and wide absorption spectrum at high temperature and better power attenuation performance, power plant efficiency rather than the size of the silicon power plant is about 10% higher.
As we all know, the crystal silicon route has been dominated in the global photovoltaic industry. But before 2009, along with the continued hot market in Europe and the United States, global polysilicon prices also soared to a record peak, rising cost of crystal silicon solar cell, thin film batteries also makes the advantage of low cost to reach the maximum level, which also spawned the rapid development in the period of the thin film solar cell industry.
OFweek industry research center data show that the development of this period can be grand global thin film solar cell industry. In 2007 the global thin film solar cell production reached 400MW, a 06 year 181MW growth of 120% in 2007, thin film solar cell market share increased from 8.2% in 2006 to 12% in 2007, and in 2008 reached 15%-20%. 2008 global thin-film solar cell production reached 892MW, an increase of 123%. And in 2009 Solar First a company's output reached 1.1GW, ranking first in the world.
But we know that this period of film solar cell development, mainly by the Solar First as the representative of the CdTe technical line to promote, CIGS technical route of the advance speed is obviously slow a lot of. The MiaSol (recently acquired Chinese hanergy holding SolarFrontier, Wurth (Solar), in 2012 by the German Manz acquisition), Nanosolar as the representative of the overseas enterprises in conversion efficiency increased year by year, but it is not enough to achieve substantial breakthroughs in share in the market level.
In contrast, China's domestic CIGS industry started late, restricted by the production equipment and technical bottlenecks, industrial development has been slow. Relevant data show that before 2001, the domestic research in CIGS thin film solar cell unit is few, slightly affected Tianjin Nankai University and Tsinghua University Department of Mechanical Engineering Research Laboratory of functional films, after heavy ion Peking University Laboratory of Tsinghua University and Department of materials science and engineering, University of Science and Technology of China, Inner Mongolia University, Yunnan Normal University, University of geology etc. have begun to carry out CIS system solar cell. Because of the national investment funds is less, the battery technology is difficult, only the Nankai University to maintain in the Tianjin Natural Science Foundation and the national key science and technology under the auspices of the billing amount, in the "fifteen" period CIGS solar cell was included in the National 863 key project, the battery has made considerable progress in the development Chinese.
In recent years, many domestic manufacturers China increasing investment in this area has been the emergence of a number of enterprises, Shandong sunvim solar hina holding group, Tianjin, Suzhou etc. ysolars Taiyang photoelectric. Industrial applications, also appeared in the first talk about Yunnan Shilin 1 MW thin-film solar power plant project, but it is enough to make China solar photovoltaic industry confidence inspiring project, but because the core technology from Germany, and make the country frequently in the field of "satellite", but still have not seen many manufacturers substantial progress the embarrassed.

So, what are Chinese market topped the Manz group's CIGS technology what originality? After the author deeply research to sort out the following ideas. Although Manz group was founded in 1987, but the group's CIGS technology, the earliest date can be traced back to 1975. At that time, the Electronic Physics Research Institute of University of Stuttgart, which opened the CIGS technology laboratory research, has accumulated a wealth of knowledge. With no technical background, solid China enterprises, dozens of years of sedimentation, the Manz group has historical and technical basis of deep solid in the field of CIGS security.
Today, Manz group has become the world's only CIGS component production experience of equipment suppliers. Manz CIGS turnkey production line adopts the linear co evaporation source, high-end technology is unique in the world, under a certain scale of production capacity, yield of CIGS components through the core technology of Manz production rate is more than 94%, significantly enhance the efficiency of more than 15.3%. Even more critical is the use of a large glass of local materials, can significantly reduce the cost of materials and plant construction costs.
