2009 is undoubtedly the harsh winter of the electronics industry. In the face of the market in Minqing, even the industry predators such as Intel, SMIC and Zhongxingwei have also made helpless layoffs. In the margins of the electronics industry, solar products are unique. Our days are much more moisturized than those that have the honor of electronic mainstream products. Huang Ming is blunt about this. He is the chairman of Huangming Solar Group. In the past fiscal year of 2008, they achieved sales revenue of about 4.23 billion yuan, more than three times more than in 2007.
Tempting cheese
Although there is no authority to count the total sales of global solar products in 2008, from the optimism of major manufacturers, they should have good progress in the past year. Xu Yong, Marketing Director of Zhejiang STI New Energy Co., Ltd. believes that the tide of reform and opening up is more powerfully impacting every corner of China. The fruits of reform and opening up can be seen everywhere, and the world-famous Chinese economy has achieved continuous leap. Development. With the deepening of reform and opening up, the living standards of residents have also made a qualitative leap. Especially in recent years, the income gap between urban and rural residents has been shrinking, and the income of comparable residents of rural residents has increased significantly, making the purchase of the largest consumer group in China. The ability has been greatly enhanced, and the package capacity of various industry markets in Mainland China has also increased with the geometric progression. Many domestic and foreign investors face the big market of China's development, and none of them can sit back and ignore them. They have long been eager for this big and attractive cheese, and they are coveted. Right now, the biggest opportunity for this crisis to bring to solar companies is the opportunity for strategic adjustment. Home appliances to the countryside, solar energy to the countryside, and the new rural market has become the survival choice of many solar energy companies.
For small and medium-sized enterprises involved in heating, electronics and housing construction, the solar industry is a business area with great potential. On March 26, 2009, the Ministry of Finance issued the “Implementation Opinions on Accelerating the Application of Solar Photovoltaic Buildings†and the “Interim Measures for the Management of Financial Subsidy Funds for Solar Photovoltaic Building Applications†to support the demonstration of photovoltaic building applications and the implementation of solar roof plans. The integrated application of photovoltaic building, subsidies for building optoelectronics utilization in rural and remote areas, and the subsidy standard in 2009 are set at 20 yuan/Wp. As soon as this news came out, the solar energy concept stocks in the secondary market collectively blowout, among which Aerospace Electromechanical, Leshan Power, Sanxia New Materials, Tianwei Baobian, CSG A, Vosges and other varieties have even pulled up two daily limit, the plate The heat suddenly increased. The solar theme in the Hong Kong market also benefited from the mainland policy. Sunshine Energy (0757.HK) rose 21.9% last week, Xingye Solar (0750.HK) rose 16.67%, and Zhifu Energy (1051.HK) rose even more. 69.09%. The US market on the other side of the ocean also smelled business opportunities. Option traders began to frantically pursue Chinese solar-related companies. Suntech’s share price rose 44%, Jiangxi Saiwei rose 32%, and Jingao rose 42%. Driven by favorable policies, the solar energy production capacity of a considerable number of enterprises will be digested. In the long run, the current development of the solar industry is only the beginning, the solar sector is ushered in a sunny day, the fat market of the solar market is really attractive.
Current status of solar technology
Solar energy is an ideal energy source. At present, solar power generation technology in the world can be roughly divided into three categories: solar cells and matrices, and solar cell technology is a major component of solar power technology. The photoelectric conversion efficiency of solar cells is an indicative indicator of the comprehensive performance level of material properties, device structure, preparation technology, process equipment and testing methods. The photoelectric conversion efficiency of solar cells is divided into two types. One is the research and development level of small size (for example, 1cm2): 24.7% for monocrystalline silicon solar cells, 19.8% for polycrystalline silicon solar cells, 15% for amorphous silicon solar cells, 18.8% for copper indium selenium solar cells, and GaAs solar cells 33 %, organic nanocrystalline solar cells 5.48%. One is the commercial production level of large size (for example, 1200cm2): monocrystalline silicon solar cell 15%, polycrystalline silicon solar cell 12%, amorphous silicon solar cell 8%, copper indium selenium solar cell 10%. The above data were collected from published literature and may have changed.
Increasing the photoelectric conversion efficiency of solar cells is the main means to reduce the cost of solar power generation equipment. The conversion efficiency is high, and the solar cell matrix area can be reduced and the amount of solar cell modules can be reduced under the same power generation capacity. Therefore, it has become the main development direction of solar power generation technology.
