Single crystal, single crystal grab popular solar high-efficiency topics fermentation

Due to the fact that the governments of various countries have focused their subsidies on the roof of solar panels, the limited area has been used as the focus of development, and high-efficiency solar energy products have attracted attention. The conversion rate of polycrystalline solar cells with high market share has reached around 17%. Considered to be gradually entering the bottleneck area, it is difficult to effectively break through, and thus MonoLike has recently received attention from both sides of the Strait. However, single crystals have not been put into mass production, and some companies believe that it is more efficient to directly develop single crystals. Recently, it has become a situation where single crystals and single crystals actively grab popularity.

As the major subsidy countries include Germany, Italy, the United Kingdom, and several major US states, the area of ​​solar power (Ground) has been substantially cut off in subsidies, and the subsidy for installing rooftop solar systems has been strengthened to make it possible to cover a limited roof area. Exerting the maximum power generation efficiency has become an important topic in the near future. The sluggish economy after the second quarter of 2011 has caused the relatively high number of high-efficiency solar cells and single crystals with relatively limited production capacity to be reduced.

The solar energy industry said that since the second quarter, the market has been actively studying how to improve efficiency. Since the conversion efficiency of polycrystalline solar cells is estimated to be around 17% will reach the bottleneck area, in addition to the increase in the difficulty of increasing conversion efficiency, plus On the current low prices of solar wafers and batteries, and the great degree of mass production after the investment is difficult to hang guarantees, resulting in relatively small investment and recycling benefits, which also makes some companies hesitate.

Therefore, the polycrystalline industry expects to invest in single-crystal technology under relatively small changes in the existing technology. The general efficiency of single crystals is considered to be more than 17% or 17.2%. For the round end, including the effective change of the thermal field at the expected cost, or the use of seed crystals, the number of reuse of seed crystals, the cost of production, and even the yield rate are all part of this breakthrough.

At present, some companies have proposed strategies to ensure efficiency levels, but not every investor can guarantee that, for battery manufacturers, they still have to change the original process. This has also caused some companies to hesitate to invest in module manufacturers. In fact, the single-crystal maple leaf pattern is currently rejected by some systems and consumers. The representatives of the mainland single crystals include Yuhui, Jingao, and GCL-Poly.

Solar energy industry experts say that once single crystals break through the existing problems, they are expected to expand the theater for the mainstream polycrystalline market. After all, polycrystalline silicon has gradually entered the problem of difficult to effectively improve conversion efficiency, and some industry players believe that it is not relevant to them. The problem of investing in single crystals and processing it is not as good as investing in the development of a relatively mature single crystal market. However, due to the problems of materials and production costs, single crystals are still dominated by the mainland market, and due to the large number of investors, the quality is also different. Doping it.

It is not worthwhile to invest in Taiwanese companies. This is also estimated to be one of the main reasons for the limited polycrystalline silicon in China and the United States. However, Sino-U.S. twins are also the target. Representative, the product has been circulated in the market.

Lin Helong, general manager of Green Energy, said that to invest in single crystal must choose the technology and cost are more competitive areas, only the benefits of investment, Green Energy has begun the field of single crystal cutting, follow the Japanese market are used The diamond cutting method, while the field of long crystals is still being evaluated, must meet the prerequisites of technology and cost.
