Ge develops carbon nano diodes for solar cells

Ge Corp Global Research Center (GE Global Research) is a Ge Corp specializing in scientific research institutions, the day before it revealed the development of carbon nano diode technology, carbon nano diode technology will be used to develop cheap solar technology, solar cell technology is being developed at present. This is the last year, the global research and development center, Ge Corp announced the improvement of the novel carbon nano diode device.

Ge Corp senior nanotechnology leader Margaret Blohm said in a statement: "the Ge Corp to develop carbon nano diode devices not only the success of that Ge Corp is a pioneer of electronic technology in the new era, the success of the new technology potential discloses a solar research channel. The discovery of the photoelectric effect in our carbon nanotube devices will lead to an exciting breakthrough in the field of solar cells. People can not only get more efficiency of solar cells, in the mainstream battery energy market, consumers have a more viable alternative."

Ge Corp's Global Research Center said, different from the traditional diode, carbon nano diode developed by Ge Corp to perform a variety of functions, a diode and two different types of transistor capable of emitting and detection of sunlight. The diode is formed by the connection of a P type and a n type semiconductor material. In the carbon nano diode device developed by Ge Corp, two regions are formed by electrostatic doping technique. Using two separate gates connected to the carbon nanotubes of the, the P-n junction of the carbon nanotubes can be formed by a cathode bias and other anode voltages used.

Ge Corp scientists have found that an ideal diode can stop the recombination of the middle part of the carbon nanotubes. These results show that carbon nanotubes are very sensitive to contact with the substrate. This finding provides an important clue to any working principle of carbon nanotube based devices.

Ge Corp's Global Research Center pointed out that in the process of light energy conversion into electricity, through the test parameters, carbon nanotubes scientists further elaborated the performance of ideal diode, while providing energy is 1000 times smaller than the wavelength of light, but because of the increase of physical parameters like diodes, carbon nanotubes show important energy conversion efficiency.

The development of carbon nanotube diode technology is a part of the Ge Corp development plan, the Ge Corp for the development of new technology to ensure the level of investment will be more than two times in the next five years, reaching $700 million to $1 billion 500 million. As part of this commitment, the Ge Corp Global Research Center will actively arrange for the development of photovoltaic technology to study the cost of energy generated by sunlight and more efficient.
