A diameter of 20 cm of the “glass” put together under the sun’s energy could light a cigarette a few seconds. This is a College of Chemistry and Molecular Sciences, Professor Liu Lijian demo scene.
Professor Liu Lijian said that this is actually a polymer condenser plate, in theory, sunlight intensity can be increased in recent times, the gathering of solar energy can generate temperatures above 600 ℃. His discussion group is using this condenser plates in the solar energy into chemical energy of the “low carbon” technology research.
“Low-carbon economy” is a hot topic in the Copenhagen Climate Conference, before that, the Chinese government for the first time quantified the world public commitment to emission reduction targets, ThinkPad T60 battery the decision to per unit of GDP by 2020, greenhouse gas emissions below 2005 levels by 40% – 45%.
“Low-carbon economy” is essentially to reduce fossil fuels such as coal, petroleum use, as much as possible use of biomass energy, wind energy, solar energy. “Low-carbon economy” rely on technology to ensure implementation. This reporter learned that, in Wuhan University, active in a group engaged in “low carbon” technology experts and scholars, who use biomass, wind, solar and other aspects of the research has been getting better, in the promotion of high-carbon to the “low carbon” , “zero carbon” solid scientific research into the road.
Since 2003, Liu Jian discussion group trying to gather solar energy biomass carbon dioxide and the reaction of carbon monoxide as straw, will not only direct use of solar energy to biomass into gas carbon monoxide, and carbon dioxide into carbon monoxide can also the process of turning sunlight into chemical energy, in order to achieve carbon dioxide recycling, save energy, increase energy, reduce emissions and protect the environment of multiple effects . The process has been completed a small simulation experiment is under way to expand testing.
Liu Jian, China’s annual production of straw is only about 11 million tons, all of them using only the equivalent of less than 400 million tons of carbon, can not meet the huge demand for social and economic development. For this reason, his discussion group also try to gather sunlight directly into carbon dioxide, carbon monoxide, ThinkPad T43 battery ，ThinkPad T43P battery so not only energy saving, is also expected from the “low carbon” to “zero carbon.”
National New Century 100 million project to train selected persons, Wuhan University, School of Physics, Professor Zhao Xingzhong the discussion group is dedicated to solar cell research, some technologies are close to the world advanced level.
New solar energy as a renewable energy, is considered the most important new 21st century energy sources. To the semiconductor material silicon solar cell, represented the first to flourish. But the production process complicated and costly. In recent years, scientists have been in countries committed to developing a number of low-cost, highly efficient new solar cells. Low-cost dye-sensitized solar cells in recent years scientists of research.
Professor Zhao Xingzhong the auspices of “dye-sensitized solar cell” research in unique home and abroad. Beginning in 2006, over 863 items of the discussion group “solid polymer electrolyte modified nanocrystalline dye-sensitized solar cell research,” by ultrasound irradiation, nano-particles doping technology, targeting solid electrolyte modified. Dyes excited by the sunlight, the electrons into the TiO2 porous film by TiO2 transmitted to the external circuit, can be directly solar energy into electricity. ThinkPad R50 battery ， ThinkPad R50e battery Dye-sensitized solar cell production process does not produce carbon dioxide, does not produce environmental pollution. Unlike traditional silicon solar cells compared to dye-sensitized solar cell silicon cells cost only 1 / 5.
