We have seen silver and gold nanoparticles have been used on top of plasmonic solar cell to increase the light absorption. Now, the magnetic properties of silver and gold have any effect on solar cell? What i mean, whether the material used on top of solar cell, it;s magnetic properties have any influence on solar cell?
Thank you in advance
The effect of magnetic properties on solar cells is still unexplored. I don't think that they have any significant effect.
Dear Dr. Nicolò Maccaferri
Thank you very much for your comments.
Yes, both silver and gold are diamagnetic at bulk level but I have seen reports where it is told that they show magnetic properties when they are in nano or, pico scale. You might like to have a look at the following reports.
For silver: http://cds.cern.ch/record/951900/files/0605160.pdf
For Gold: http://download.springer.com/static/pdf/27/art%253A10.1007%252Fs13404-010-0002-5.pdf?auth66=1422266589_e2d3df095b05623e8b571c3b03415976&ext=.pdf

Dear Dr. OMKAR SINGH KUSHWAHA
Thank you for your valuable comment. I also have been looking whether there is any effect of magnetism in solar cell. But till now, haven't got any report regarding that.
Best Regards
Interesting question, but I would like to agree with Nicolo on this one. Even if the Ag clusters do exhibit some magnetic properties, I am not sure this will affect the device performance. Generally, the B-field does not interact with light, the exception being only in the case of the Faraday rotation which requires special crystals. With reference to solar cell, I doubt if this field is huge enough to interact with the e-h pairs significantly in the device.
I would be curious how EM fields generated by plasmonic particles affected neighboring EM fields of plasmonic particles, and so forth.
