California Institute of Technology has recently developed a new solar cell, whose basic principle is that the matrix of silicon thin line integrated into the substrate polymer. In most things thin and flexible, its absorption of solar radiation and the photoelectric conversion efficiency have made important breakthroughs. inspiron 2650 battery , In addition, traditional solar cells needed for the amount of semiconductor material expensive compared to this new type of solar cells need only a small part.
Applied Physics and professor of materials science at HarryAtwater and HowardHughes said: “These solar cells for the first time crossed the traditional materials of the absorption of light to pick boundary.” New type of silicon used in the matrix cells Solar on a single line of wavelength of incident light, the absorption rate of up to 96% and the rate of capture of full light at wavelengths up to 85%.
Rate of opto-electronic conversion of up to 100% new solar cells can be successfully developed Curl
Atwater said: “Many of the materials ability to capture light very well, but it can not be converted into electrical energy, such as black paint. For solar cells, the absorbed photon is converted to electrical charge can the child (chargecarrier) is also very important. “While they have developed a range of lines of silicon solar cells can be absorbed by the photon 90-100 % converted to electronics. Technically, this table has a near-perfect internal quantum efficiency (internalquantumefficiency). sony vgp-bps9
Atwater concluded: “The high light absorption and better conversion success jurisdiction of this high quality solar cells.”
Silicon wire arrays of silicon line length from 30 to 100 micrometers (microns) between the diameter of only 1 micron. The thickness of the whole network is equivalent to the length of lines of silicon, but from the perspective of an area or volume, only 2% of this material is silicon, the other 98% of all polymers . As the cells of traditional silicon solar ingredients in a very expensive, pa3285u-1bas , so that the amount required for a 50 traditional production costs of solar cells are much lower.
