A latest technology has been discovered by Stanford University research that may possibly guide to cheaper and more efficient solar cells, but the latest model is not as much of powerful as the status quo.
Adding a slim layer of organic molecules to every solar cell, Stacey Bent, a Chemical Engineering Professor said she considers that her “quantum dot” technology could boost effectiveness threefold, incise manufacturing expenditure and finally show the way to lesser retail prices for consumers. Bent talks about the technology Sunday at the yearly meeting of the American Association for the Advancement of Science in Washington, D.C.
Bent said in a statement, “I doubted if we could make use of our knowledge of chemistry to get better their effectiveness.”
Experiment of Bent unlimited the way solar cells produce electricity. Sun strikes the cells, stimulating electrons, and they jump to superior energy levels. It comes so quick that the electrons leave a hole, similar to a shadow, in their old place. This response reasons an electrical current, ensuing in solar power.
Mainstream solar panels are prepared of silicon, a single material and arrive at an utmost effectiveness of 31 percent. For the reason of the additional organic layer in the technology of Bent, effectiveness could achieve three times that. According to the statement, her group, nevertheless, has only attained .4 percent effectiveness thus far.
The statement said that the material she is utilizing is not perfect for solar technology, so Bent prepares to conduct experiment with other organic materials and perhaps modify the whole plan of the solar cell. These modifications might make the most of the effectiveness, according to the statement, and might guide to a broader recognition of solar technology.
