Hi,
I am working on solar cells with plasmonic nanoparticles embedded on the top. In many literature's I have come up with near and far field effects.
What are the significance of near and far field scattering in a solar cell, due to the NP's?
Both of them can enhance the absorption, but near field is strong and EM field will decay as the distance increases. For far field and near field, they shows different scattering patterns. You should care about this point for proper designs. For thin film solar cell, if the active layer is very thin, near-field enhancement is more important.
