According to foreign media reports, along with energy-efficient solar cells, small organic molecules successfully developed, can be printed like a newspaper from the solar panels become a reality even more so. This from the University of California, Santa Barbara research group developed a solar cell's energy efficiency is 6.7%, with the best performance of polymer solar cells comparable. Most of the energy efficiency of polymer Sony Np-ft1 Battery 6% to 8%.
Including Nobel Prize winner Alan - Professor Haig authors, including 7 in the "natural materials" paper published in the journal, wrote: "These findings make the solution processing of organic photovoltaic technology has made significant progress and confirmed that the use of small molecules solar cells made of polymers with their version to compete against. "
Materials scientist at Monash University in Australia - Chris McNeil, said the paper indicate that this area has made the new "significant" progress. Scholars from around the world and industrial laboratories are organic solar cell devices of tireless research, because they have to make flexible, low-cost mass production of solar energy equipment for the potential.
Although this new type of solar cells installed on the roof with many of Australia's performance of silicon solar panels similar, but their manufacturing costs will be lower, and the ultra-light and flexible features will also be used in a variety of different ways to make them even used on uneven surfaces. University of Queensland for Organic Photonics and Electronics Center, Paul - Professor Meredith said, most people so far mainly focus on the development of organic polymer solar cells. However, these cells are difficult to control and production, because they are generally difficult to achieve size and performance of a unified standard. He said: "If I collected a bucket of this polymer Canon Eos 1100d Battery, and see each molecule, I will find them in size and shape are very different, and these novel small molecules, as long as you make the appropriate synthesis, each molecules will be the same, so you can better control and production of solar cells. "
Meredith said the next step is to produce a conversion of energy to maintain this level of commercial-size models. Solar panels on the roof area of about 10 square centimeters, and published in "Nature Materials" magazine in the small molecule solar cells is only 0.196 cm2 effective area. He said: "The current problems facing the organic solar cell is made in proportion as we try to larger equipment, we produce the best (energy conversion), only a few percent." There are still problems, including: whether small-molecule solar cells made of a larger area of the Canon mv500 Battery, it will still maintain the efficiency of this change, and whether it can achieve industrial-scale production standards.
Meredith said, but it is "a very beautiful molecule, can be described as first-class quality." "I was amazed to get such a good electrical properties, it can escape so perfectly self-organization." McNeil said the main benefits of organic solar cells is that they can use a similar method as the newspaper , using reel to reel printing process to produce low-priced products. He said: "If you can produce ultra-light, efficient and low-cost modules, people will embrace it (the use of organic solar cells) roof without any infrastructure changes, because you can spread it on the roof, clung to it, and then power.
