Asymmetry in photocurrent enhancement by plasmonic nanoparticle arrays located on the front or on the rear of solar cells

Beck, F. J.; Mokkapati, S.; Polman, A.; Catchpole, K. R.


We show experimentally that there is asymmetry in photocurrent enhancement by Agnanoparticle arrays located on the front or on the rear of solar cells. The scattering cross-section calculated for front- and rear-located nanoparticles can differ by up to a factor of 3.7, but the coupling efficiency remains the same. We attribute this to differences in the electric field strength and show that the normalized scattering cross-section of a front-located nanoparticle varies from two to eight...[Show more]
