Canada captured two new solar cell technology bottleneck

Electrolyte and the electrode coating material is more than 20 years have affected the development of new solar cell technology, two major problems. Canadian scientists in the latest issue of the Journal of the American Chemical Society “and” natural Huaxue “magazine published by Shang FeNb related research, is the point of view of industry Zhuanjia successfully solve these problems is low cost, high-tech solar cell efficiency Xinxing a major breakthrough in the development of solar cell technology is important. laptop battery

Earth in 1 hour of energy from the sun than humans within a year the total consumption of energy. However, compared to the potential of solar energy, the current application of solar energy is not optimistic. Silicon used in today’s conventional solar cells, the production cost of traditional energy sources, coal, oil and hydroelectric energy costs 5 times to 6 times. For years, scientists from different countries working to develop more efficient and cheaper solar cells.

In the early 90s of last century, Swiss scientists have used the principles of the invention of a new type of photosynthesis, solar cells, solar cells, but the presence of electrolyte corrosion, bad properties light transmission and low voltage output gaps. gk479  , Electrolyte corrosion, leading to questions of life; electrolyte dark in color, is not conducive to efficient light grace photovoltaic weak electrolyte, which limits the output voltage can not exceed 0.7 volts .

Existence of such a solar cell technology is another problem cathodic need to use expensive and opaque coverage of platinum metal. Over the years, Switzerland has invented the solar cell of the above problems were not dealt with effectively, may not be practical.

Professor of Chemistry, University of Quebec, Canada Benoy Tema Hulsen led the research team has long been engaged in research in electrochemical solar cells, has won a number of technology patents. They have developed the chemistry of the two solar cell technology can effectively solve problems encountered by Swiss scientists. pc764

First, the problems of electrolyte, Marcin group in the laboratory has developed a new electrolyte, characterized by transparency, non-corrosive and can improve the PV. Second, the scientists replaced the expensive platinum-cobalt sulfide as the coating material coated electrode. cobalt sulfide, in addition to relatively inexpensive, but also with greater efficiency, better stability and ease of preparation in the laboratory and so on. vgp-bps9
