Binding causes the development of solar cells
How should gradually get rid of dependence on fossil fuels by humans? It is the world's governments and scientists worked to solve the problem. Renewable energy is definitely the preferred alternative to fossil fuels and solar energy as an affordable, abundant renewable energy, Hp laptop battery is the focus of researchers to explore. However, HP 417066-001 Battery,HP F4486B Battery, HP F4486A Battery, the low conversion efficiency of solar cells has always been the stumbling block of the human use of solar energy. Currently, the maximum conversion efficiency of conventional solar cells is only about 30%. However, this situation will soon be a revolutionary breakthrough. U.S. researchers have a new breakthrough in solar cell technology could allow solar energy conversion efficiency of cells of two degrees, directly from the current 30% to 66%!

Recently, in "Science" magazine, University of Texas at Austin chemist Xiao-Yang Zhu (transliteration), Dr, on semiconductor nanocrystals (also called quantum dots) in the latest study showed that conventional solar cells conversion efficiency of 30% longer limited to the effectiveness of more than 60%.
Binding causes the development of solar cells
The reason why the conversion efficiency of solar cells will be more, because scientists have found a way to effectively capture in conventional solar cells to heat loss out of shape at high energy of the Sun method currently being use most of the major silicon solar cell efficiency is only about 31%, because the sunlight in solar cells, sunlight has a lot of energy too large can not be converted usable energy, energy that is the so-called "hot electrons" form, the form of heat loss.

If these high energy solar light, hot electrons can be captured, then the sunlight conversion efficiency of electricity can be theoretically increased to 66%. University of Texas Center for Materials Chemistry, Chemistry Professor Zhu said that the conversion efficiency of solar cells so amazing called "the ultimate solar cell." To create such a battery, take several measures. First, the slower cooling rate hot electrons; HP F4486A Battery, Second, these hot electrons lose their energy before, to be able to capture and use as soon as possible.
Quantum dots to solve problems
Zhu explained that the amount of semiconductor nano-dot grain or simply respond to the use of "hot electrons" requirement,HP 417066-001 Battery,HP F4486B Battery, HP F4486A Battery, primarily because quantum dots hot electronics could allow heat to slow-release this in several research institutions have been proven. In the 2008 "Science magazine, a document of a research team at the University of Chicago research results show that colloidal semiconductor nanocrystals can be sure of reaching the slow cooling of hot electrons to that effect. Now The research team of Dr. Zhu has solved the problem of the second critical step, namely, how to obtain and use these hot electrons. Dell Vostro 1014 battery Dell Vostro 1015 battery
University of Texas study found that hot electrons can be optically excited PbSe nanocrystals of titanium dioxide to the driver of electrons, electronic conductor and titanium dioxide is now widely used, is very easy to obtain.
"If we can eliminate these electrons, we can leave as I have used. This transfer of thermal electrons as Zheng Ming Biaoming a very effective solar hot carrier Liu Zi Dian Chi Jin Jin is no longer a theory Gainian while Yeju You experimental possibilities. "Dr. Zhu introduced. Although researchers use quantum dots of lead selenide, HP F4486B Battery, but Dr. Zhu said that their approach to the quantum dot other materials are also applicable.
Mr. Zhu also reminded people that this is a small step is a science still need more science and engineering studies will be a Zhizao Chu Zhuanhuan Xiaolvgaoda 66% of the solar cell.
It is also worth mentioning that at the moment of Mr. Zhu, who works to solve the scientific problem of the third aspect: the hot electron to connect to cable. dell latitude d410 battery dell latitude d420 battery
Mr Zhu said: "Even if we remove them from the sun's heat, the rapid flow of mail, but they connect over the same heat loss or damage. So our next goal is to adjust the son related to electrical interface between chemistry and characteristics, to minimize the loss of additional energy. We hope that the greatest access to sunlight into energy, which is the ultimate solar cell. "Research project as a whole by the U.S. Department of Energy provided financial support.
