The global warming issue continued to be concerned about everywhere in the development of alternative energy sources, Taiwan National Chiao Tung University "cross-cutting photoelectric research center similar to the general plastic material, developed the world's highest efficiency of organic solar cells.Easy ways to obtain not only does not have a serious shortage of raw materials like silicon, can be folded and bent, estimates can enter the home, the market value of up to $ 1 billion in the next 3-5 years. 

   According to Taiwan's ETTV reported difficult to promote traditional solar panels because the larger, National Chiao Tung University R & D team to produce the energy conversion efficiency of 5.2% plastic solar cells. And compared to traditional silicon solar cells, organic solar cells of the biggest advantages is that the battery materials produced similar to everyday use of plastic raw materials, and easy to obtain, the price is very low. 

"National Chiao Tung University of Electro-Optical Engineering Assistant Professor Chen Fang said, using the solar energy is not popular, so, once successful listing of organic solar cells will become the trend of the future. He said, and compared to traditional silicon solar regulator, these solar cells are thin, flexible features, so it can be combined and daily life. 

   Chen Fang pointed out that the future can be flexible home solar panels folded into the size of the pocket, always close at hand, such as mobile phones, if there is no electricity, you can use solar cells to charge, but can also be combined and notebook computers, or devices in the top of the tent, to travel to the outdoor field soldiers, a conservative estimate by 2011, the market value will reach $ 1,000,000,000. 

, Solar grade polysilicon worldwide, there is a big gap, industry profits have been higher. With China's energy policy is increasingly inclined to environment-friendly new energy polysilicon production quickly spread in the policies and interests drive under. "Only a few years, the country now has 19 places in a polysilicon project, everywhere. 

Jiang Xiaoting certainly the one hand, the prospect of silicon materials industry, on the one hand, this "everywhere" another view, the development of silicon materials industry can not go before the herd instinct, blindly launched the old path of industrial development, and should be based on the rational distribution of industry characteristics. The silicon material discharge of toxic substances in the process, only supporting the project with the horse, take the road of recycling economy, in order to avoid environmental pollution, sound and rapid development.

So I think, should focus on the construction of large industrial base, even as water, electricity, gas, roads and other infrastructure common share, and can concentrate on controlling pollution and avoid duplication. In addition, part of the key technologies in the polysilicon purification has not yet grasp, focus on building a large industrial base, but also to avoid the large amount of spending money, repeat the introduction of technology. "

 U.S. and Indian scientists found in organic photovoltaic materials (organic photovoltaics, OPV) coated with a polymer containing boron nitride nanotubes (Boron-nitride), can significantly increase the life cycle of the solar modules.University of, (Wake Forest University) and the Indian Institute of Technology (Indian Institute of Technology) researchers found that at concentrations of 1.5% nanotubes, will be able to maintain a high degree of transparency in the visible range, enhance heat protection. 

    Polymer solar cell to compare the efficiency of the silicon solar regulator, but have the diversity, and can be applied on a flexible substrate, and therefore still optimistic solar energy intake. However, OPV because of oxidation, exposure to moisture or photochemical reactions and shorten the working life, cause the component to drop (degradation). The David Carroll University noted that the UV light may affect the performance of the polymer component, but if the scattering or absorption to reduce the influence of UV light, the component life can be extended. 

    Boron nitride material for ultraviolet a good scattering effects, while the high aspect ratio nano-tube structure can provide a greater amplitude of oscillation, showing a better behavior of the antenna, therefore compared to the average boron nitride thin film nanotube structure can be a more effective absorption of UV light. In order to produce the boron nitride nanotubes, the team will be equipped with boron, iron oxide, and magnesium oxide, quartz crucible placed in a horizontal alumina tube growth in the environment of 1200 ° C ammonia for 30 minutes, after natural cooling The resultant powder, and then concentrated nitric acid to remove the catalyst particles to leave a multi-wall boron nitride nanotubes. 

    Researchers to packaged food sialon (Saran) as a polymer matrix, this material is good denial of oxygen and moisture better transparency in the visible band, and has good mechanical and thermal stability. In order to assess the degree of protection of the components, the team measured the spectrum of the coated and uncoated composite thin film organic electronic materials P3HT and found that the latter is exposed to the atmosphere for 24 hours on a downgrade signs. And the former joined the nano-materials, but still 93% transmittance in the visible range, far exceeding the 90% of the minimum standards for solar modules.

    In addition, this team has to do in this material 50 to 850 ° C between the assessment of the thermal stability, and found significantly better than the undoped material mixed with 1.5% concentration of boron nitride material on the thermal stability. See Nanotechnology recent. 
  
  Johnson PV buy solar panels power plant using amorphous silicon thin film battery has a significant low-light effect, amorphous silicon cells can still generate electricity in the morning and evening, rain and fog and other low-light conditions than crystalline silicon cells, in the same lighting conditions, the amorphous silicon thin film battery years power generation increased by 12-15%. Attenuation Johnson amorphous silicon photovoltaic power plants using battery power in a high temperature environment, crystalline silicon solar cells in the temperature exceeds 25 degrees when the camera when the photoelectric conversion rate of the formation of the rapid decay curve, while the amorphous silicon small changes, this feature enables the non- crystalline silicon thin-film battery is more suitable for high temperature, high desert regions of use and construction of photovoltaic power plants. 

    Johnson photoelectric production of amorphous silicon thin film batteries and the construction of photovoltaic power projects the maximum characteristics and advantages of solar cell products prices decline, the cost of power generation for about 40% of the crystalline silicon cost of power generation, photovoltaic power generation in the central and western China remote areas, especially the shortage of film popularized in applications possible.

 In the photovoltaic industry chain, the inverter has always been considered one of the links is the most technical threshold. Or why, in 2010, the photovoltaic industry crazy expansion, the expansion of the inverter industry was slightly some of the "rational", and in the subsequent industry-wide rapid price, the price cut and the speed was much more moderate. 

However, since the second half of 2012, the market price of the inverter wave of rapid fill-off, high-power cut by about 8 cents per watt to about 4 cents. For a single watt inverter price is not that high, so fast and up to 50% price cut, no doubt their ability to control costs severe challenges. 

Known as the inverter is able to produce as well as sporadic shipping companies in the market, also have sprung up hundreds. The competitive situation of the domestic inverter market, a time of intense unprecedented. As Shaanxi Changling Photovoltaic wind inverter Electric Co., Ltd. (hereinafter referred to as "Changling PV) current chief engineer and chief technology officer, graduated from Xi'an University of automatic control professional OF RADIO, almost in Changling Group engaged in the power of the" lifetime " electronic product development and technology management. 2010, Changling PV inception, OF RADIO has served as the main technical person in charge, and accompanied by Changling PV development and growth so far. 

In early April 2013, "mppt solar charge controller power" magazine reporter went to the Changling PV headquarters is located in Baoji City, Shaanxi Province, an exclusive interview OF RADIO PV inverter technology development and the current competitive situation and other related issues. "Inverter there is indeed a technical threshold" Some people think that the inverter is the photovoltaic industry chain, not more than a technical threshold link, how do you think this is? OF RADIO: the development and manufacture of photovoltaic inverters, a variety of techniques involving power electronics, power conversion technology, maximum power point tracking technology, phase-locked loop technology integration, safety, EMC, power quality and conversion efficiency have a more high demand. 

Same time, the photovoltaic system to run two or three decades particularity in the open-air environment, but also put forward higher requirements on the use of reliability and life of the inverter, its life must be more than two decades. Due to the integration of various technologies, and the use of environmental constraints, different from the PV inverter power electronic products have special requirements, its design, production and quality control. Therefore, relatively speaking, the inverter indeed be regarded as more of a part of the technical threshold in the photovoltaic industry chain.

 Foreign media reports today, the EU will start from June 6 to 47% levy punitive tariffs on Chinese solar panels, which is the second after the United States announced that the area of ​​anti-dumping tax rate of the Chinese PV panels, the Chinese photovoltaic say "no. "India. Of high growth and prosperity, the Chinese PV industry with the start of the world economic crisis, into the embattled position.

U.S. time last year, the afternoon of March 20 (Beijing early morning of March 21) announced the preliminary countervailing duty rate of the time difference, because China and the United States, I know of several photovoltaic inverter with charger industry insiders evening almost no sleep. The results came out, thankful the countervailing duty rate of up to 4.73% of the results, but he begins to worry about anti-dumping tax rate may be less than satisfactory. The last preliminary anti-dumping tax rate of up to 250% and, indeed, to the Chinese photovoltaic lose. 

See foreign media reports, I called to the Yingli Director of Public Relations beam field, he did not expect to be so long out of the news, because the arrangements in accordance with the time of the anti-dumping cases, before announcing the preliminary results in June, the EU so early news release, Nada was slightly surprised, but the mood that's about it. My attention on the microblogging many photovoltaic who are not on the news published opinions. Telephone contact with a few of the more familiar people, most of the reaction is "oh" sound so simple, do not want to say anything. 


In fact, the United States decided to file for the Chinese photovoltaic panels at the end of 2011, the domestic photovoltaic companies have begun to concern about the European Union will follow. The litigious German PV companies SolarWorld was first in the EU to lobby the government to initiate an investigation of China home solar panels  PV, did not achieve their goals after the turn brought in the United States double reverse, the United States', the EU filing is sooner or later. 

Over the past year, the media are bad-mouthing PV. Afterthought analysis of photovoltaic reasons for the decline, such as two out of raw materials and markets, excessive government support, are the main reasons mentioned. But most of the photovoltaic industry is to blame for the environment, the world economy is poor, Europe and the United States set up trade barriers in China, was chosen PV, on the one hand is irksome enough in the world photovoltaic industry accounted for the share, on the other hand, photovoltaic industry subsidies exist, relatively easy to operate. 

Li Yang, director of the CASS Institute of Finance warned, as the economic crisis continued, a greater danger is approaching, and that is developed is developing a new international rules, the tendency of the new rules is to improve the normal exchanges of all countries of the threshold .

 May 6, media reported that a few days ago, the Ministry of Finance to the provinces under the Department of Finance issued the "Ministry of Finance on the liquidation of the Golden Sun Demonstration Project financial grants," which called on the 2009-2011 Golden Sun project has been completed and The grid project subsidy standards liquidation cancel the demonstration project is not completed in time or power to recover funds set aside. Stipulated by the Ministry of Finance audit deadline of June 30 this year, the specific criteria under the Golden Sun Batch different.

Ministry of Finance notified as follows: ,2009-2011 demonstration project completed in accordance with the required deadline and acceptance test upon completion and final accounts, and power generation, according to the corresponding subsidy be liquidated. ,2009-2011 demonstration project is not completed within the prescribed period, cancel the demonstration, to recover the funds set aside. ,2009-2011 demonstration projects completed within the prescribed period, but not in time for the completion and acceptance of the accounts, or the grid, project recovery funds set aside,

Among them: the first, demonstration projects in 2009 and 2010 was completed within the prescribed period, the audit has not yet completed but in the June 30, 2012 to complete the final acceptance and final accounts, or you're done with the completion and acceptance of accounts, but not the grid polycrystalline solar panels power generation, can be completed by June 30, 2013 and grid generation, audit handling of clearing. Although completion of the project June 30, 2012, final acceptance and final program is not completed or not yet the grid on June 30, 2013, to cancel the demonstration eligibility to apply for liquidation.

2011 demonstration projects have been completed in the June 30, 2012, final acceptance and final accounts and other related procedures but not to the grid, can be completed by June 30, 2013 and network operation generating procedures and go through the liquidation of assets; 2013 June 30 has not yet grid-run power generation projects, cancel the demonstration eligibility to apply for the liquidation of assets. Demonstration disqualification projects such as the continued implementation of distributed photovoltaic power subsidy policy, according to the relevant regulations of the State enjoy.

Due to lower-than-expected global PV Photovoltaic Panels installed capacity in 2012, the photovoltaic business capital chain tight, photovoltaic international trade protectionism, the Chinese PV companies suffered serious losses, the photovoltaic companies listed at home and abroad in the fiscal year 2012 almost all of the deficit. Countries to ease the domestic enterprises to survive the pressure has up to 4.54GW Golden Sun projects approved in 2012. Golden Sun Project does not really solve or alleviate the capacity crisis of the Chinese PV companies. It is said that feel the pressure of the Ministry of Finance to rectify the failure for various reasons had completed Golden Sun Project has launched an emergency and grab fashions, the second quarter of PV installed capacity will be ascribed.
