Chloroplasts of green plants through photosynthesis,  rechargeable laptop battery  which converts sunlight into chemical energy. Inspired by photosynthesis, scientists are working to develop a theory of the chloroplast is similar with the new battery - dye sensitized solar cells can convert light into electrical energy, a "true zero emissions."

PV industry as a new force in the field of energy has become a high tech industries in Jiangsu, one of the fastest growing. However,  sony VGP-BPS5 battery as the representative of clean energy, the chain of cells of the silicon solar industry silicon material input materials is energy intensive and heavily polluting industries. To this end, scientists have begun the preparation of new materials developed for use in solar cells.
Through photosynthesis of green plants, we may not be familiar: The chloroplast, absorb and utilize light energy, carbon dioxide and water into organic material stored energy and release oxygen.

Throughout this process, as there is sunlight, photosynthesis can still continue.

Called "Dye-sensitized solar cell (hereinafter DSC)" works with the principles of photosynthesis is similar. The difference is that the photosynthesis of green plants throughout the chloroplast, DSC photosynthesis, using chlorophyll is similar the dye to absorb sunlight, dell inspiron e1405 battery,dell inspiron e1505 battery  produce electronic, electronics no longer collecting electrodes, and then through the external circuit to return against the electrode, the photocurrent.

These cells are considered the research on solar energy and development of another "Dawn". Nanjing University of Technology, Professor Feng Xiaodong recently told reporters that the battery is the next generation of low cost solar cells. If the battery has proven successful, will allow the use of clean energy in millions of households.

Bright have electricity?

"The whole cycle, as there's sun, and with the external circuit connected, we can always convert the charge of energy." Plasma Physics, Chinese Academy of Sciences Institute DAI Song-Yuan introduced the battery works: When the dye molecular absorption of sunlight, the electronics started to become active and the state of the natural soil titanium dioxide and the oxidation reaction occurs, then returns electronically to the electrode surface of the collection, hp f4486b battery,hp f4809a battery  leaving the circuit, while returning from the other side of the electron trap electrode electrolyte ions and return to the oxidation of dye molecules to re-return to the ground state, which complete the cycle of electron transport.

However, Xiaodong Feng also said, DSC photosynthesis and photosynthesis of different plants. Chlorophyll molecules in plants can be said is that DSC used in the dye molecules in nature. With the similarity of plant photosynthesis is absorption of light excitation molecular charge transfer. Behind the difference is that the steps not the same as for DSC is passed over the two electrodes to collect the charge, resulting in electricity, while photosynthesis,  charge transfer to the reaction center, forming new connections chemicals, it will install solar replaced by chemical energy.

Geometric new battery cost?

"DSC producing cost, simple and environmentally friendly, and can be prepared on flexible substrates." Feng Xiaodong introduced, compared to silicon solar cells, sony PCGA-BP1N battery , sony VGP-BPL5A battery such as preparation of thin film photovoltaic cells of the DSC is very simple, it was one of the main advantages of the battery.

In addition, DSC abundance of raw materials, low cost and stable performance. Cell production process is mainly a large screen surface printing technology and the method of simple immersion is conducive to mass production industry, and all raw materials and production processes are non-toxic, without pollution, the battery in the driver's window can be fully recovered, the protection of the environment is important.

DAI Song-yuan said that the energy of the DSC can be directly solar energy into electrical energy to large scale production of photovoltaic electricity, China to solve the vast central and western regions, energy issues without electricity of great importance. It has established an account in the long term, if the DSC lower the cost of 10 yuan per peak watt, the cost can be considerable with conventional energy sources. If the yield of 7% per square meter will be a 70-watt battery-powered, then an area of 14.3 square kilometers can reach 1000 MW of power capacity.

Battery bottleneck where?

For PV to become a part of future energy systems, the key is to achieve its performance cost with conventional energy sources can be quite. Dai Song-Yuan has brought cost advantages of DSC, such as 6% of the photoelectric conversion efficiency, stability in the open air, reaching more than 10 years, it has the potential for industrialization. But the DSC,ibm thinkpad r60 battery,ibm fru 92p1141 battery   as a period of time prolonged outdoor facilities will have a variety of natural conditions. Therefore, the study of long duration, high stability of the DSC is a very urgent matter.

Xiaodong Feng noted that the dye sensitized solar cells Another problem is the dye molecules to present its light absorption efficiency is not high enough. Exposure to solar spectrum on earth is very broad spectrum, 49% concentrated energy in the infrared light, while the vast majority of dye molecules present on the efficiency of absorption of infrared light n is not high. Therefore, the absorption efficiency of dye molecules synthesis have also become a very important direction of research.

Would replace silicon-based solar power?

In 2004, industrial research, DAI Song-Yuan of the research team in a leading position in China. They prepared a large area tandem cell module (15 × 20cm2) of the initial efficiency of 5.9%, stability, efficiency of 5%. The industrial production for the next step and lay a good foundation.

He explained, the next main objective of DSC is the technology and process manufacturing industry, push for further progress, which seeks to solve the battery long time stability and efficiency of components of the battery once popularization and application,  require at least 15 - the stabilization period of 20 years. But in the long run, to be truly low-cost applications in solar cells, dell gk479 battery so that ordinary people can afford is the way the key.

Feng Xiaodong that the photovoltaic cells will in future become an important safe and reliable new energy. DSC, as a kind of photovoltaic cells, has its unique applications market, of course, it can not replace the current silicon based on the dominance of solar energy.

"Artificial Leaves" zero emission

PV industry as a new force in the field of energy has become a high tech industries in Jiangsu, one of the fastest growing. However, as the representative of clean energy, the chain of cells of the silicon solar industry silicon material input materials is energy intensive and heavily polluting industries. To this end, scientists have begun the preparation of new materials developed for use in solar cells.

Nanjing University of Technology, Professor Feng Xiaodong, said the journalist, in which a new type of solar cell, using a good performance, low-cost nano-titanium dioxide as an anode of the battery, then a layer of nano - titanium dioxide on the absorption of solar light-sensitive organic dye, so they are called dye sensitized solar cells. It's simple and easy to obtain the raw material production, the process is not complicated, function as a leaf, it is strongly urged "artificial leaves".

And the leaves compared to dye sensitized solar cells used in dyeing, as the leaves of chlorophyll in the sunlight, will produce electronics, nano-electrodes of titanium dioxide are assembled collection of electronic devices. This battery as long as lighting, it will continuously produce electronics, solar energy directly into light and will not discharge waste.

Thin as onion skin, can easily fold

We learn that because titanium dioxide has a good transmission of visible light, so this "artificial leaves, almost transparent, and thin as onion skin and can be freely bent, dell 6400 battery  with materials and structures for continuous improvement, this magical "tree leaves" very optimistic about the prospects for commercialization.

According to experts, this transparency "leaves" If you have a large area, it is possible to replace the glass, so to receive the light, we can provide leadership within the small appliances you can also provide energy of outdoor advertising. On the desert plateau, as long as one mounted on the roof equipped with "artificial leaves" big tent, that small cars can provide the impetus for long distance travel, when people do not need 's worry about a lack of car fuel, but also eliminates the Voyage of excess baggage.

In addition, flexibility and transparency of the retractable battery is not only comfortable, but also on several levels, and increase the use of sunlight in space satellite will be the new favorite food or satellite.
