PV industry as a new force field of renewable energy has become a high-tech industries in Jiangsu, one of the fastest growing. However, the current value of the silicon-based commercial solar laptop battery based on polysilicon materials, but are high-energy consumption and high pollution products. To this end, scientists have considered the development of more new materials, preparation of solar cells.
Thin as onion skin, you can freely bend sunlight that is able to power - At the recent annual meeting of the 2009 Nanjing Association for Science, Nanjing University of Technology Professor Feng Xiaodong said, inspired by photosynthesis, the experts working on the development of a chloroplast structurally similar new compaq EVO N400c battery - dye-sensitized solar cells. This shaped like "artificial leaves" of the battery can be light energy into electrical energy, and achieve a true "zero emissions."
PV industry as a new force field of renewable energy has become a high-tech industries in Jiangsu, one of the fastest growing. However, the current value of the silicon-based commercial solar cells based on polysilicon materials, but are high-energy consumption and high pollution products. To this end, scientists have considered the development of more new compaq Presario R3000 battery materials, preparation of solar cells.
Feng Xiaodong, said the new low-cost solar cell using a good performance of nano-titanium dioxide anode for the battery, and then a layer of nano-titanium dioxide on the absorption of the sunlight-sensitive organic dye. This dye is like the chlorophyll in the leaves, in the sunlight irradiation, will produce electronics, nano-titanium dioxide electrodes are assembled collection of electronic devices. This battery as long as there is light, it will continuously produce electronic, will light energy directly into electricity, and will not discharge any waste.
"This cell structure similar to the 'sandwich' is a layer of nano-hollow 'sandwich'." Feng Xiaodong, said the tricky the compaq Presario V4000 battery hidden photoelectric conversion layer in the tens of microns thick composite film. To make dyes as much as possible, "eat" the sun, researchers ingenuity to Caesar the point "seasoning" - a kind of fluorescent material by the nano-quantum dots, so that different wavelengths of light can be right on the "light-harvesting hand" The "appetite." Believe that continuous improvement "recipe," nano "sandwich" of the photoelectric conversion efficiency can be increased again and again.
"Dye-sensitized cells the biggest attraction is the cheap raw materials and simple production process." Feng Xiaodong, said the compaq Presario V5000 battery is equivalent to the cost of silicon panels is only 1 / 10, which can provide the impetus for indoor small electrical appliances can also be to provide electricity for outdoor billboards. In the desert plateau, as long as one mounted on its roof fitted with "artificial leaves" big tent, we can power small cars, people worry about the lack of fuel cars, but also eliminates the extra baggage travel.
In addition, the flexible and transparent retractable battery is not only comfortable, but also layered, and enhance the utilization of sunlight in space in a spacecraft or satellite power will be the "new favorite." It is learned, Southeast University and Nanjing University are carrying out this new type of solar cell research, experts compaq Presario V2000 battery are looking for more efficient organic dye, in order to further enhance the "artificial leaf" of the photoelectric conversion efficiency.
