Solar photovoltaic companies expect gradual revolution
Not like the industry, as expected, the beginning of 2012 did not bring the photovoltaic industry any comfort. In the past the first quarter, the major PV companies have resorted to embarrass earnings miserably. IMSResearch PV market research firm recently released research report, the first quarter of this year, polysilicon, wafers, cells and modules and other photovoltaic market price are the main products have been diving in the first quarter of polysilicon, solar cells and modules, respectively, the average price fell 48 %, 57% and 44%. Moreover, once the largest cell manufacturer Q-cell collapse, FirstSolar and SUNPOWER downsizing cuts and other negative news constantly heard many a time the domestic photovoltaic industry is making determined efforts, paranoia, bankruptcy, rumors Guantingbingzhuan refreshed daily. This photovoltaic industry bloodbath seems far end. How to survive in the storm is a problem the moment PV companies are most concerned about. Do not you see CEOs running major photovoltaic lobbying to get more support from the government; component enterprises have set foot in the downstream power plant, just want to sell more than a few board; in order to save costs, companies Xiaojiannaodai looking for new technologies and new materials and new technology. For businesses, how to play it safe? Nothing more than well-known high efficiency, low cost, but it is truly difficult. PV industry experts have told the author, with the process of continuous improvement and progress, as the existing first generation of crystalline silicon cells, its efficiency and cost almost reached the limit, especially photovoltaic panels on the front of the craft, already close to the maximum optimization If you want to break, bound to a revolutionary technology. Ion implantation, passivation, selective emitter technology, the second printing technology, double-layer metal wiring, selective diode, back-contact technology industry have become concerned about the second-generation photovoltaic cell technology. I see a sample at Applied Materials of the second generation of photovoltaic technology, with the biggest gap of the first generation of products is to shift all the metal wiring to reduce rear cover, ensure panels can receive more sunlight, while using anti-film to reduce surface defects, reduce reflected sunlight. According to Zou, chief technology officer of Applied Materials has just revealed that the conversion efficiency of the second generation of photovoltaic cells may reach 20% or more, the recession has dropped significantly. The so-called second-generation photovoltaic cells does not seem very far away from us. Sales, general manager of Applied Materials' solar energy and Market Development Division Xiao Jinsong told the author, on 2012, the R & D center in Xi'an Applied Materials on the second printing, select an emitter, new passivation technology has been to more than 50 PV companies demonstration. And Tianwei New Energy Holdings Co.'s chief technology officer, said Dr. Zhang Fengming, Tianwei back-contact technology has been a huge breakthrough, and is expected to be commercialized in the near future. The second generation of photovoltaic cells is not a great leap forward and closer to the progressive revolution. Or, the second generation of photovoltaic technology can be split as many "building blocks" of technology, and the "building blocks" of different options will set up different types of second-generation photovoltaic cells. Zou Gang said with a smile: "For each client, the second generation of photovoltaic technology has numerous combinations, like Transformers, each company will have used different techniques for the second generation of photovoltaic cells." Breakthrough technology is inseparable interaction and common progress of the whole industry chain. The second generation of complete photovoltaic cell technology and commercialization efforts needs of the entire industry. With the yield improvement, technological innovation itself, the extent of decline in the cost of materials and automation technology continues to improve, solar energy subsidies will be gradually transformed into one of the major energy sources can rely on, which is just around the corner. Suntech Zhengrong Shi, chairman told the media that the next 10 years, PV face transition period of 10 years. I believe that, in addition to technological innovation and industrial chain optimization, the most important change that is the reliability and value of photovoltaic power generation has been the mainstream of the energy of recognition and support. The transition is not easy. As the second generation of photovoltaic technology needs on the basis of a generation of optimization and upgrading innovation, photovoltaic road development also requires linkage and multiple large industries, such as improving the smart grid will help make better use of solar energy; less electricity for the region without electricity It helps, PV will play a significant role; with the carbon dioxide emission reduction requirements, PV status will become increasingly important. No one doubts that the future of PV, but can not wait until tomorrow, for the moment PV businesses is a problem.
