According to foreign media reports, successfully developed organic small molecules as energy-efficient solar cells, solar panels that can be like a newspaper printing step closer to the reality. This United States University of California, Santa Barbara, the energy efficiency of solar cells developed by a research group is 6.7%, and currently the best performance of polymer solar cells comparable. Energy efficiency of most polymer batteries in between 6%.
, Including Nobel Prize winner Professor Allen-Haig authors of recently published papers in the journal nature materials wrote: "these findings give solution processed organic opto-electronic technology made Significant progress, and confirmed that the use of solar cells made of small molecules can compete with polymer versions of them. ”
Australia said materials scientist Chris-McNeil of Monash University, the paper marked in this field have made new "significant" progress. Academic and industrial laboratories around the world are to unremitting study organic solar cell Equipment, because they have a flexible, low cost solar power potential for mass production.
While this new type of solar cells with many Australia performance of silicon solar panels installed on the roof similar to, but their production costs will be lower, and ultra light and flexible features are to yield them to various channels, even without the formation of a surface. Center for organic Photonics and electronics, University of Queensland Professor Paul Meredith said, most people so far mainly focused on the development of organic polymer solar cells. However, these batteries are difficult to control and production, because they generally difficult to achieve uniform in size and performance standards. He said: "if I have collected a bucket of the polymer batteries and see each molecule, I find that they are very different in size and shape. These new small molecules, as long as you make the appropriate synthesis, each molecule is the same, so you can better control and production of solar cells. ”
Meredith said the next step is to create a to maintain the level of energy transformation model of commercial size. Solar panels on the roof area of approximately 10 square centimeters, and published in the journal nature materials of small molecular solar cells only 0.196 square centimetre of the effective area. He said: "the current problems in organic solar cells, is when we try to make proportionally larger equipment, we produce the best of (energy conversion) only pennies. "Still has issues such as: whether the small solar cell made from a larger area of the battery, can still maintain that transformation efficiency, and whether it can achieve the standards of industrial-scale production.
Meredith said, but it was "a very beautiful, quality is first class." " I am surprised that, in order to get such a good electrical properties, it can be so perfectly organized themselves. "McNeil said that the major benefits of organic solar cells are similar newspapers follow the ways that they can, using roll to roll printing technology to produce low-priced products. He said: "If you can produce surplus light, efficient and low-cost module, then people will embrace it. (Using organic solar cells) roofs infrastructure without any changes, because you can shop on the roof, stick on top, and then power it on. ”
