Recently, the German industrial giant Siemens announced formally withdraw from the nuclear energy, in order to focus on other technical areas. Siemens CEO Pete - Loescher (PeterLoescher,,) had said in an interview for the position, the company will no longer be any investment in nuclear energy, but will continue to supply the nuclear power plant parts.
Siemens to exit nuclear energy market, will focus on other technical areas, reported, although not explicitly mentioned in the field specific, but in July this year, Siemens signed an agreement with Spain UTETermosolarOlivenza plan (Spain) Esther Extremadura Extremadura region of 50MW concentrating solar power plant equipment. The plant is expected to be operational by the end of 2012. Will be built with Siemens Solar heat sink and 123 trough solar collector array.
In Germany made it clear that will completely abandon nuclear energy, the attitude of other countries has also undergone a subtle change in the major companies in a timely manner changes in the marketing strategy. Nuclear power was abandoned, solar energy is bound to get more large-scale development, concentrating photovoltaic and solar powered led lights power have greater potential for development and space. It can be speculated that Siemens or will shift to the development of concentrator photovoltaic market.
Concentrator photovoltaic technology research began in the 1970s oil crisis, as the technology becomes more progress in recent years to achieve greater development, the world has carried out many research projects, and the completion of a number of demonstration projects. Up to now, the world spent only $ 1 billion investment in concentrator photovoltaic and small-scale investment projects, the scope is narrow.
Concentrator photovoltaic light conversion efficiency of up to 30% to 40%, about 1-fold higher than that of crystalline silicon solar cell; its life about 70 years, far higher than that of crystalline silicon solar cell for 30 years, and has manufacturing process pollution characteristics, will bring some market demand.
CPV in the solar power market, only a small part, about 0.1%. This is mainly because the newer technology and traditional photovoltaic, and higher costs, more complex. To scale CPV must reduce costs. Built so far, the largest CPV power plants installed capacity of 1 or 2MW.
Time use of the technology at home and abroad by comparison, but production also is not big enough, its mainly because of cost issues. Cost per watt is roughly the times of polycrystalline silicon cells. The high cost of concentrator photovoltaic systems a major cause of its use of III-V solar vacuum tube cells. This material was originally aerospace materials, the commercialization of photovoltaic power plants use is the last in 2023. However, due to the downstream equipment manufacturer's production capacity is not large, there is no large-scale use of natural high cost.
In recent years, more and more into the field of system vendors, so the demand of the cells has also attracted the entry of a series of chip manufacturers. Samsung, JDSU and other international companies have had to enter the field of solar cells plan, this will inevitably bring about a substantial decline of the cost, whether it is for the development of photovoltaic industry or enterprise, are no doubt good news. Like the early polycrystalline silicon cells, with the further maturity of the technology, the market will continue to become larger.
In addition to the cells, the technology also requires solar tracking systems, mechanical systems, electronic systems, optical systems, cooling system to a concerted, thus technical difficulty much higher than traditional polysilicon thin-film battery system.
Will be held November 28 -30 at the Shanghai World Expo Exhibition 2011 China PV power generation and system integration technology Symposium and Exhibition (PVChina2011) set up a special concentrator photovoltaic special invited concentrator photovoltaic experts, business executives concentrating photovoltaic power generation system are facing technical problems and solutions, large area solar concentrator tracking technology, to balance the condenser lens mode advantages and disadvantages, the most viable lens condenser mode and materials The selection of a reading and discussion. It is reported that the chief technology officer of the North control Green Technology Industry Co., Ltd. Mr. Lin Chuanyi (born in Taiwan, graduated from National Chiao Tung University. Expertise for the study of concentrator photovoltaic materials and power plants) will be titled "megawatt-class concentrating photovoltaic power plant equipment industry "speech, in addition the PV meeting are also invited to the Shanghai Ju Heng solar companies, the Japanese core PV Technology Co., Ltd., Sichuan in the Han solar power, Taiwan Fang energy relevant person in charge of science and technology, Amonix, AZUR SPACE Solar Power GmbH, and other corporate keynote speech, to discuss the concentrator photovoltaic current level of technology and the future direction of development.
According to industry estimates, as more companies increase production, in 2015, the CPV market each year will more than double. Concentrator photovoltaic systems with high photoelectric conversion efficiency, small footprint, less energy consumption and production and other advantages, no doubt for future large-scale photovoltaic power plant technology, to become the star of the next generation of PV. Although the cumulative installed capacity of the condenser system of the ground is still very small. But concentrator technology has broad industry and technology development, space, and concentrator photovoltaic scale development just around the corner.
