江苏省倾力打造千亿光伏产业 欲称雄世界太阳能光伏第一省

在过去的10年里，随着世界光伏市场需求量的大幅增加，加上大规模制造技术的不断提升。推动了全球光伏产业的高速发展．光伏电池产量从1995年的78．6MW，提升为2006年的2600MW。特别是现在，太阳能光伏在全球处于快速发展时期，最近10年（1996-2006年）年平均增长速度为40％，最近5年（2001-2006年）更是以每年45％的增速发展着。预计2010年年产量将达10GWP-11GWp。[第一段]     

我国光伏产品出口遭遇的严峻挑战分析

近年来,我国光伏产业快速发展,规模不断扩大。我国已成为全球第一大太阳能电池出口国。但是,2012年我国太阳能光伏产品出口额同比下降35.0%,出口数量同比下降8.1%,表明我国光伏产品出口面临严峻挑战。主要原因是由于目前我国光伏企业缺乏核心技术、出口市场过于集中、国内市场尚未全面启动等问题造成的。为此,我国要采取有效措施加以应对：积极应对欧美的“双反”调查、加快实施光伏企业“走出去”战略、提高光伏企业自主创新能力、加速启动国内市场等。如此,才能促进国内光伏产品的出口。

Electrotechnical requirements for PV on buildings

World‐wide the number of grid‐connected PV systems is growing fast, especially in the built environment. In order to assure the quality and energy output of these systems, a number of electrotechnical requirements need to be fulfilled, at both component and system levels. In addition requirements with respect to electrical safety need to be met. Part of these requirements are covered by international standards, especially with respect to the PV modules. A number of standards is still under development. In the area of systems and utility interfacing local codes are still in use. These local codes differ significantly from country to country.

Global maximum power point tracking based on new extremum seeking control scheme

A new perturbed‐based extremum seeking control (PESC) scheme is proposed in this paper to track the global maximum power point (GMPP). The PESC scheme has two control loops based on power of the photovoltaic (PV) array: the first loop operates as usually to track the maximum power point and the second sweeps all local MPPs to locate the GMPP. Once the GMPP is located based on its uniqueness (after the PV pattern is quickly scanned many times, depending on the PV pattern's profile), the GMPP is accurately tracked based on first control loop. The used PV patterns have the profile of the PV power characteristics obtained for PV array under partially shaded conditions (PSCs). This PESC scheme is proposed to track the GMPP in the PV applications, but also in other multimodal problems from industry, being a good motif to revive the specialists' interest for the extremum seeking control field. The results obtained here are very promising for both search speed and tracking accuracy performances of the GMPP under different PSCs simulated on the PV array. Thus, the energy efficiency of PV array controlled with the proposed PESC scheme will increase with more than 1.2% in comparison with that obtained with the other MPP algorithms because of better performance shown by this PESC scheme. A 99.6% tracking accuracy is obtained here in comparison with a maximum 98.4% tracking accuracy reported in the literature. Furthermore, 100% hit and high search speed are obtained here for the GMPP localization. Copyright © 2015 John Wiley & Sons, Ltd.     

Photovoltaics in an architectural context

In well‐populated areas, such as western Europe, PV is often integrated into the building envelope. Despite the fact that there are many examples showing that PV can be an aesthetically neutral or visually attractive element in architecture, many BIPV systems display few architectural qualities. But if well applied, PV can increase a building's character and value. Within Task 7 of the IEA PVPS programme a team of experts with an architectural background studied which key requirements needed to be complied with (design criteria for good‐quality PV projects) in order to produce successful PV integration. These criteria are discussed in the article. PV is not automatically considered an indispensable material in architectural terms. This is why, no matter how well it is integrated, PV remains an ‘added’ element. Architects can take this as their starting point and can use one of the design approaches that are presented in the article. These criteria for incorporating PV in the building design and the design criteria for good‐quality PV projects are important to architects and architectural critics in determining why a BIPV project, be it their own design or that of a colleague, is or is not aesthetically pleasing. This offers learning opportunities and reasons for follow‐up or improvement options. Architects who apply PV in a well‐thought‐out way can make their clients very happy, and thereby contribute to a greater acceptance of PV technology. Copyright © 2004 John Wiley & Sons, Ltd.     

The Chinese silicon photovoltaic industry and market: a critical review of trends and outlook

With manufacturing capacity ranking number 5 in the world in 2005, China is rapidly emerging as an important player in the global silicon solar cell and module market. Production capacity has been growing by more than 70% per year over the last 7 years and future ambitious plans for the further expansion of the domestic production are likely to transform China in one of the largest (if not the largest) PV hubs in the world. However China's ability to fulfil its goals is challenged in the short term by a global shortage of silicon and in the medium to long term by the ability of the government to stimulate innovation and to introduce the necessary incentives to grow the domestic market significantly given that 80% of the production is currently exported to Germany and the USA. The article addresses these issues by reviewing the recent technological and market trends in the Chinese PV industry. It also explains the major domestic manufacturing strategies and indicates the possible future direction of photovoltaic power generation in China. The study is based on personal interviews conducted in China from May to July 2005 with the major players along the solar supply chain, as well as with representatives of the Chinese photovoltaic R&D sector and policy makers.

Global overview on grid‐parity

Grid‐parity is a very important milestone for further photovoltaic (PV) diffusion. A grid‐parity model is presented, which is based on levelized cost of electricity (LCOE) coupled with the experience curve approach. Relevant assumptions for the model are given, and its key driving forces are discussed in detail. Results of the analysis are shown for more than 150 countries and a total of 305 market segments all over the world, representing 98.0% of world population and 99.7% of global gross domestic product. High PV industry growth rates enable a fast reduction of LCOE. Depletion of fossil fuel resources and climate change mitigation forces societies to internalize these effects and pave the way for sustainable energy technologies. First grid‐parity events occur right now. The 2010s are characterized by ongoing grid‐parity events throughout the most regions in the world, reaching an addressable market of about 75–90% of total global electricity market. In consequence, new political frameworks for maximizing social benefits will be required. In parallel, PV industry tackle its next milestone, fuel‐parity. In conclusion, PV is on the pathway to become a highly competitive energy technology. Copyright © 2012 John Wiley & Sons, Ltd.
