UNSW to obtain silicon cells 43% of the conversion efficiency record

University of New South Wales (UNSW) researchers in the solar cell efficiency of another step in a few days ago they reported that 43% conversion efficiency of the new world record. The research team and the United States more than two teams demonstrate the performance of the battery combination, the efficiency of the establishment of a new benchmark.

Professor, Martin Green "Because solar energy by different composition of many colors, ranging from high-energy ultraviolet light to low-energy infrared light, as opposed to a single cell, different combinations of materials, solar cells more efficient conversion of sunlight," UNSW ARC Photovoltaic Center of Excellence, research director Martin Green said Professor.

Green and his colleagues Anita Ho-Baillie to lead R & D team has developed a silicon battery optimization technology, in the solar spectrum of the red and near-infrared side to capture sunlight. The battery capable of up to 46% of sunlight converted into electricity. When combined with four other batteries (from the National Renewable Energy Laboratory and the Emcore Corp. Joint development), each optimized for different solar spectrum band, the combination of the five batteries eventually be able to convert 43% of sunlight into electricity, will be The original world record of 0.3%. "Our R & D team of silicon cells is the key factor to reach a new record," Green said.

UNSW new record last year to create a single solar cell 25% of the world record can not be directly comparable, ARC Director of the Center, Professor Stuart Wenham said. "The latest record contains a combination of expensive batteries, and the collection of sunlight generated by the density is much higher than that of the standard tests sunlight intensity," he said. "However, it does show some of the final feasible solution."

LDK Solar to develop solar energy projects in China

LDK Solar Co., Ltd. Tuesday said it is in cooperation with China Yancheng in the next five years of building 500 megawatts of photovoltaic solar power projects, sending its shares up 6.2%. The news come out a month ago, China launched a long-awaited plans for large-scale solar power projects to offer subsidies. As the world's largest emitter of greenhouse gases, China is currently looking for alternatives to fossil fuels.

Since China announced the plan has been, China solar energy companies, including Suntech Power Holdings Co., Ltd. and ReneSola Ltd. Announced plans to build large solar power plants in China. "We believe that the growing number of photovoltaic application projects will come from China, we will continue our efforts to smoothly promote the rapid development of LDK PV market," LDK Chief Executive, said Peng Xiaofeng.

LDK shares on the New York Stock Exchange stock market closed 8.85 U.S. dollars, then rose to 9.40 U.S. dollars after. Yancheng City in China Jiangsu Province, is located north of Shanghai city. China 6 month that it will speed up the development of Jiangsu Province, which will include Yancheng.

Lieberose become Germany's largest solar power station

Wrrstdt in Germany and the United States juwi Group of First Solar Inc. announced that during the construction of solar power generation market Brandenburg Lieberose Thursday to become the world's second largest, Germany's largest solar power station. 560,000 in the first solar panel installation is complete, the German foundation and the Ministry of Construction Minister Wolfgang Tiefensee Brandenburg Matthias Platzeck Chief Minister made this announcement.

Turnow-Preilack still located in the construction of solar power generation market in several aspects of solar energy industry can be called a landmark project. Despite the current economic and financial crisis, the two companies are still in the construction of utility-scale projects, a total investment of more than 160 million euros. The project is about generating 53 megawatts, covers an area of more than 210 football pitches, is the world's second largest photovoltaic installation projects.

Germany's Minister of Construction Wolfgang Tiefensee the basis of the formal start of the ground-breaking ceremony for 300 invited guests, said: "Lieberose projects in Germany show local renewable energy production and other advantages of combining the success of these advantages include local companies, networks, research organizations and universities have the knowledge and expertise. Germany's competitiveness is to rely on this combination. "

He added: "Lieberose not only in power generation and financing is an example of changing the military and other unused land is also true. Over the years and prohibits the entry of contaminated land under the arms and the removal of other pollutants, not all of the land - the countries - to have any financial burden. Lieberose solar power market is to make solar power become a major force in the local economy an important step. "

This project was originally developed in the Soviet army in Germany's largest military training base. Because of relatively low investment and operating costs, the user can be attractive to the Brandenburg to pay the rent for the venue to provide funds to repair. Restoration measures include the removal of residual metals and hand grenades, artillery munitions debris and contaminated land. After the end of the lease term, solar power market can be removed and the land restored to natural state.

Stephan Hansen, general manager of First Solar and juwi director Matthias Willenbacher said: "Our aim is to clean, cost-effective realization of the global supply of solar energy. Lieberose project will only help to reduce carbon dioxide emissions of 35,000 tons. We project particularly proud, because it contains another meaning of the word clean (clear). It is not only clean energy output, but also ensure the removal of dangerous weapons. "

As a general contractor, juwi partner juwi Solar GmbH is responsible for planning, logistics, construction, supervision and delivery of the final completion of the solar power market, after the completion of the power generation market is expected to be sold to certain investors. Willenbacher and Hansen said: "Lieberose such as solar power generation market for all the future of renewable energy are very important. Produced through the use of solar panels the size and efficiency, which contributes to the achievement of significant reduction in the price, to accelerate the competitive force the emergence of solar power. This is undoubtedly increased awareness of the acceptability of solar energy. "

According to the plan, Lieberose will be fully operational by the end of this year. After the completion of some 700,000 thin-film modules (First Solar, mainly from the vicinity of Frankfurt / Oder factory) will produce enough green electricity to meet the equivalent of approximately 15,000 families in the demand for electricity. In addition to the production of solar panels, First Solar is also helping to fund this project.
