Polaris solar PV net news: recently, the solar Zhuang Yan, Deputy Chief said in media interviews, single crystal and polycrystalline are differentiated in terms of cost. Environment, then select the will for change, Canadian solar PV industry is not a single, solar stick to single crystal and polycrystalline coexist.
This passage can be hot “single crystal” of striving to be a summary. Zhuang Yan, illustrates a basic idea, technically don’t SideTrack, let the market choose the right product.
According to the survey, Trina solar, solar, Crystal Australia, Crystal branch, Taiwan Motech, new Sun 17 major companies, are long grain, but none of these polycrystalline bosses give up Crystal, save reckons single crystals, polycrystalline 2015, these enterprises capacity utilisation rate was 100%, but single crystal production capacity, either silicon or battery, underemployment. Early 2016, which did announce in varying degrees by 9.5 gigawatts of monocrystalline cell production capacity, the overall capacity of 40%. Plan completed in 2016, the right time, respectively, adjust production according to market demand.
Due to 2015 two quarter yihou more Crystal has been stock, caused end began needs to ready-made of Crystal transfer, Crystal products with market overall warmer and heating, especially China market, are put PV lead who plans, distributed PV understanding into “efficiency high” of Crystal, no note to PV lead who plans is on Crystal, and more Crystal, and film component are developed has different of efficiency lower, in provides lower on, procurement component see efficiency, more see price, that price, degrees electric cost (LCOE).
What’s more, the poly is not inefficient products.
Multicrystalline efficiency often exceeded 20% bottleneck enhance potential
Over the years, poly was considered low conversion efficiency, low-priced products, the conversion efficiency of the theoretical limit is 20%. However, efficient launch of first class manufacturers have already made the remarks proved unfounded.
September 2014 ja announced that by using independent research and development of advanced light trapping and passivation technique, polycrystalline solar cells solar energy conversion efficiency of the company at 20%.
In November 2014, Trina declared, by a third party authorized organization test, its research and development of large-area (156x156mm) of industrial-grade polycrystalline solar cell world record. This Si module using superposition and efficient battery technology and technology of high efficiency polycrystalline ingot, large square at the industrial level polysilicon (156x156mm) photoelectric conversion efficiency of as high as 20.53% on a substrate.
In December 2014, wet black silicon technology into the production line of solar, 0.4% (absolute) battery efficiency gains. All along, the polycrystalline diamond wire cutting promotion subject to matching by cell texturing process, seriously reducing the battery efficiency. Wet black silicon for solar development technology solves the problems, accelerating the speed of polycrystalline cell efficiency has become the standard technology of polycrystalline solar cell count capacity.
In April 2015, Trina declared, the use of independent research and development of pilot production HoneyPlus preparation of high efficiency polycrystalline silicon solar cell PV module (based on 60 156mmx156mm multi), via a third-party authority tests the photoelectric conversion efficiency of as high as 19.14%.
March 2016 jinko said in a white paper issued, ATP is committed to the development of black Silicon technologies, through special surface light trapping, multi crystalline cells pile structures close to the Crystal, reflectivity and optical absorption rates than single crystals. In May 2016, jinko said, and its use of PERC and black Silicon technologies of high efficiency polycrystalline cells has entered the production stage, by 2015 production efficiency had reached 20.13%, and efficiency in mass production this year is expected to rise to more than 20.5%.
In June 2016, said hanwha energy, based on leading Q.ANTUM back passivation of batteries (PERC) technology, the standard poly module conversion efficiency record. Vladimir Braun Hough CalLab laboratories confirmed the polycrystalline solar module conversion efficiency 19.5%, power and 301W.
These data indicate that, product conversion efficiency of polycrystalline 20% bottleneck has been a breakthrough.
The past two years, diamond wire cutting in polycrystalline areas to promote large-scale, effectively reducing the production cost of the polycrystalline, but due to higher surface cleanliness, high light reflectance. Black Silicon battery technology can enhance light trapping properties of polycrystalline silicon wafer surfaces, dramatically reducing high reflectivity from diamond wire cutting, perfect solution for polycrystalline silicon wafer texturing problems pile structure close to the CZ single crystal products. Meanwhile, PERC battery technology in the field of polycrystalline is a widely used, p-type polycrystalline solar cell capacity in the world is shifting to PERC technology is expected in the near future to the general process of p-type crystalline silicon solar cells.
PERC and diamond wire cutting technology patent is no longer single crystal and polycrystalline products are increasingly sharing technology dividend. Diamond wire cutting technology combined with black silicon, integrated PERC battery passivation technology on the back, have a 1+1+1>3 effect, can radically improve the conversion efficiency of polycrystalline cells and polycrystalline products enhance the potential remains huge.
For single crystals, brand leaders say
“Solar stick to single crystal and polycrystalline coexist”
Solar Zhuang Yan, Deputy Chief in an interview with new energy network, said: “the single crystals and polycrystalline are differentiated in terms of cost. Single crystal in efficiency is higher, the same area can generate more electricity, but if large power, low cost land and labor cases, poly instead of better. Environment, then select the will for change, Canadian solar PV industry is not a single, there are many types of PV power station, large utility, distributed, and are doing, so solar stick to single crystal and polycrystalline coexist. ”
“Provide the best single crystal polycrystalline remains the preferred product”
In the first quarter of 2016, apt finish to 1600MW quarterly shipments of components, won the world title and create best score in history. ATP Vice President Qian Jing said in an interview with SOLARZOOM, “from the global PV market is relatively mature and develop early country, Crystal is still preferred. They have a lot of power real power data showed polycrystalline and history of work in the field environment decay and reliability than single crystals. The same 280 Watt single crystal and polycrystalline 270 Watts, customers are more likely to choose Poly. ”
However, judging from the recent, rapid development of single crystal. Qian Jing explained: “mainly because on the one hand and single crystal silicon chips late last year let the market effect is remarkable, on the other hand, polycrystalline capacity is in short supply, some customers will choose Crystal products. ”
“The ATP’s goal is to form polycrystalline will develop. “Qian Jing stressed,” not that we don’t do single crystal, but we want to give customers the best single crystals, just like we give customers the best Poly. Almost all brands of manufacturers, both with single-crystal production capacity, but we don’t push, mainly 280 Watt single crystal in our view is not the best product, may be compared to 290 Watts to have technological advantage. From our Japanese, European and American customers choose, they are also more willing to choose the apt 270 Watt Polycrystalline. ”
“The market started a process of single crystal, Concord will be adjusted according to the market demand of polycrystalline silicon films production and supply”
GCL-poly Lv Jinbiao, Deputy Chief said in an interview with reporters of the Chinese entrepreneurs, “despite the GCL in terms of product focus more on polycrystalline, but haven’t given up on single Crystal product development. Company is mainly used for the layout of single crystal polycrystalline ingot production of Crystal products, the launch of the Golden Crystal G2 conversion efficiency of 19.5% in a conventional battery technology, polycrystalline ingot production technology of low cost high efficiency single, cost-effective direct challenge to the pulling of crystals. In view of the current market there is a process of single crystal, Concord will be adjusted according to market demand of polysilicon production and distribution of films. Layout of Ningxia in GCL-poly has been a highly efficient n-type single crystals. Which is mainly reserved for the future 24%-25% product with high conversion efficiency, cost control to promote. ”
Markets are the best baton, maturity of photovoltaic power generation depends on the whole industry chain keep technology reducing cost and increasing efficiency, whether it is a single crystal or polycrystalline, only select cost-effective products in the market. Rational PV enterprises will choose to meet the current market products and preparations, technical and product stocks, instead of competing with a single technology. If the blind adherence to a technology roadmap, and also another route “sworn”, a way to black, this undesirable feelings, PV industry in just more than 10 years, has had the bigots have been ripped.
