Scientists are developing a newer method to replace their solar cells with nano-metal particles. As the author describes in a new article, the method has the potential to significantly improve the harvesting efficiency of solar cells.

The nanoparticle method is to correct these problems. The key to this new study is to create a tiny electronic interference called "surface plasmons." When the light hits a piece of metal it can set the surface wave of the metal. The electrons of these gravitational waves then move like a pond on the surface. If the metal forms small particles, the incident light of the particles can be scattered to vibrate and thus effectively light. If, in addition, the light is in some "resonant" colors, the scattering process is very strong.

After optical expression of her even ruined, Kelly and Albert Polman showed that when a thin layer of nanometers (billion metal particle size) was included in the solar cell. First of all, using nano-sunlight to diffuse into the solar cell causes more full, more light in the solar cell. Second, particles of different sizes and materials allow researchers to improve light trapping or poorly-performing colors.

In their work, carried out at the Institute of Physics of the Atomic and Molecular FOM Institute in the Netherlands, she even ruined and Polman display lights (red) for long-wave catching light can be improved by more than 10 people. She even destroyed and colleagues at the previous University of New South Wales showed that the efficiency of solar cells can be increased by 30% for the use of metal nanoparticles for overall concentrating.

"I think we saw from the plasmonics about three years ago." In the photonic generation she even ruined, and he has already started a new organization to study the surface plasmonics at the Australian National University. "One important point is that the plasmons for solar cells are suitable for any type of solar cell." This includes standard silicon or new film types.
