Ohio State University researchers said when the production environment of the Earth, solar-friendly, the rose could be a new “green.” Scientists have developed a new dye sensitized solar batteries (DSSC). The Laptop battery used by the color red and white, mixed metal oxide powder pink showing, you can catch the sun.
Apparently, these new pink materials, is the best material for photoelectric conversion, despite the conversion efficiency has been implemented in commercial silicon solar batteries by half, but its cost is only one fourth of solar batteries silicon.
Pink dye sensitized solar batteries is the most typical color. Most dyes contain a ruthenium, ruthenium red. With the red dye mixed with rose powder most commonly used metal oxide is titanium oxide or zinc oxide, these two types of metal oxides are white. However, researchers at Ohio University created a IBM ThinkPad R50 battery more innovative materials does color, they used metal complex, exploring different particle shapes to improve performance of photoelectric conversion.
This is the first time, researchers use non-unique dye manufacturing oxide sensitized solar batteries. Choose stannate zinc because zinc stannate belongs to the complex oxides with tunable properties. This characteristic makes the next cut of dye sensitized solar batteries possible.
Why dye sensitized solar batteries are pink rather than blue like silicon solar batteries do? Traditional solar batteries with a Dell Latitude D510 battery blue because the fight against the causes of reflective coating. These include improving the absorption of light green, light green spectrum is the most powerful solar light. Ohio University researchers developing complex materials and it is not anti-reflective coating.
Color determines the solar battery can capture the wavelength of light, scientists can change the color of the special characteristics of solar batteries optimized. Currently, the development of dye sensitized solar batteries, scientists have used ruthenium red dye obtained the best results.
If you want to get the best efficiency, we must consider access to voltage and current. The tension is a kind of material can provide the potential energy, now is the amount of material capable of transmitting the hp Pavilion dv2000 battery charge. If you can absorb a wide range of wavelengths, it would have to sacrifice power. If the absorption of energy limit is very high, can achieve high voltage, but had to sacrifice being. Researchers want to find a fair balance.
Since the 20th century, 60 years since the silicon solar batteries appeared. Since the 20th century, scientists began to develop the dye sensitized solar batteries 90. In the dye sensitized solar batteries, dye molecules cover the tiny particles of metal oxide have lived, and with the insertion of a thin film. Dye molecules capture light energy and release electrons, while the metal oxide particles was more like a thread, will be among the electronic transmission to the circuit, but the transfer of electrons between the particles may be lost. These researchers are developing tiny sony VGP-BPS5 battery nanowires to merge to be sent directly to the causes of electronic circuits.
They are also exploring the possibility of using nano-trees – nano-son-shaped tree branches etc.. Which structure is to absorb light and improve the current structure? The researchers studied tree! Leaves provide a large surface for capturing light, the branches will be transferred to the roots of nutrition. In their design of dye sensitized solar batteries, dye particles will cover the surface, the nano-trees do not grow between the leaves of these branches, electronic transmission.
Therefore, the following dye sensitized solar batteries grow a tiny tree “pink”, but other colors are also possible. Researchers are studying to work better in the new apple A1008 battery dyes and dye compounds.
