The current problems facing the organic solar cells

May 28 [Mon], 2012, 16:10
According to foreign media reports, with the success of small organic molecules of energy efficient solar cell R & D, like a newspaper printed solar panels distance become a reality one step closer. The energy efficiency of such solar cells developed by the University of California, Santa Barbara, a research group is 6.7%, comparable with the best performance of polymer solar cells. The energy efficiency of most of the polymer battery in 6% to 8%.

The authors, including Nobel Prize winner Alan - Alexander Haig, Professor, on the 7th in the papers published in Nature Materials magazine, wrote: "These findings make the solution to the treatment of organic photoelectric technology has made significant progress and confirmed that the use of small molecules solar cells made with their version of the polymer to compete against. "

Monash University, Australia, a materials scientist Chris - McNeil said, the paper marks in this area has made a new "significant" progress. Scholars and industrial laboratories around the world is unremitting research on organic solar cell devices, because they have to make a flexible, low-cost solar energy equipment for mass production potential.

Although this new type of solar cell is similar to the performance of many silicon solar panels installed in Australia on the roof, but their manufacturing costs will be lower, and ultra-light and flexible features will also apply them to a variety of different ways, and even used in the uneven surface. University of Queensland Organic Photonics and Electronics Center, Paul - Professor Meredith said, most people so far mainly focus on the development of the organic polymer solar cells. However, these batteries are difficult to control and production, because they are generally difficult to achieve uniform standards on the size and performance. He said: "If I collected a bucket of this polymer battery, and view each molecule, I will find them on the size and shape is very different from these novel small-molecule, as long as you make the appropriate synthesis, each the molecules are the same, so you can better control and production of solar cells. "

Meredith said the next step is the production of a commercial size to maintain this level of energy conversion model. Solar panels on the roof area of ​​approximately 10 cm2, while published in the journal "Nature Materials" small molecule solar cells only 0.196 cm2 effective area. He said: "the current problems facing the organic solar cells, is when we try to made in proportion to the larger equipment, we produce the best (energy conversion) only a few percent." Problems still exist including: whether small molecule solar cells made from a larger area of ​​the battery to maintain the efficiency of this transformation, and whether it can reach the standards of industrial-scale production.

Meredith said, but it is a very beautiful molecules can be described as first-class quality ". "I was surprised to get such a good electrical properties, it can escape so perfectly self-organization." McNeil said, the main benefits of organic solar cells, they can be used in papers like as using the volume-to-roll printing process to produce low-priced products. He said: "If you can produce ultra-light, efficient and low-cost modules, people will be pleased to accept it (the use of organic solar cells) roof infrastructure without making any changes, because you can spread it out on the roof, clung to it, then connect the power. "

Republican Party to win over some voters

May 28 [Mon], 2012, 16:01
The 13th U.S. President Barack Obama specifically on trade with China speech, and a rare personally announced that the U.S. has joined the European Union and Japan filed a trade action against China of restricting exports of rare earths to the World Trade Organization (WTO).

Obama said that the case involves the rare earth materials used in high-tech products from hybrid cars to the phone's battery, the United States hope that the U.S. companies in the local production of these products, but to do this, U.S. manufacturers on Chinese supply rare earth materials. He pointed out that, be able to manufacture advanced batteries and hybrid vehicles for the United States is too important to the United States can not stand.

Before his speech that morning, the United States, Japan and the EU have jointly filed a lawsuit against China to the WTO, to seek to resolve this dispute.

Obama also said, has been a constructive economic relations between the United States, the United States tend to be resolved through dialogue and friction between China and differences. But when American workers and companies are encountering unfair trade practices, he will take action.

Foreign media analysis that Obama move with obvious political overtones. In the 2012 U.S. presidential election in the context of the recent Obama on trade issues with China to take strong language, intended to hit back at criticism of the Republican Party to win over some voters. Previously, the Republican Party's leading presidential candidate Mitt Romney has been criticizing Obama's China policy is too weak.

Trade litigation, Chinese Foreign Ministry spokesman Liu Weimin, on the 13th to respond, said rare earth is a scarce non-renewable resources, the development of rare earth impact on the environment, based on the consideration of protecting the environment and resources, to achieve sustainable development, the Chinese government mining, production and export of rare earth in all aspects of implementation of management measures, and not just in the export sector, in line with WTO rules.

Liu Weimin, China's rare earth resources of the global total of 36.4%, but bear with more than 90 percent of the global supply of rare earth. Over the years, despite tremendous pressure on the environment, China has been trying to maintain a certain amount of exports of rare earths. In the future, China will continue to supply the international market of rare earth and rare earth exports in accordance with WTO rules to implement effective management.
