Greetings
I have a solar cell (silicon brick) with metallic rods on the top surface. This is well known structure to enhance the solar cell responsivity with plasmonic effects.
So I want to calculate a photocurrent that can be generated by my structure. To do this I need to know the optical generation rate in the silicon brick. Usually the following formula is used: ecee.colorado.edu/~bart/book/book/chapter4/gif/eq4_7_4.gif . But how can I take in account the impact of plasmonic structure on the top surface? Maybe I should calculate the energy flux (z component of Poynting vector) through the top surface of silicon brick and use it as an input optical power? But in this case how could I know the absorption coefficient of silicon due to a surface plasmon wavelength is shorter than excitation wavelength?
Thank you.
