(Color online) (a) Schematic of the InGaAs/GaAs QD solar cell structure used in this study. (b) SEM image of the nanoparticles formed on the rear of the solar cells and their size distribution.

Image of FIG. 2.
FIG. 2.

(Color online) Normalized photocurrent spectral response of the reference QDSC and QDSCs with Ag nanoparticles. The TiO2 spacer layer thickness is 5, 10, or 20 nm. The photoresponse of the cells is normalized. Inset shows the scattering cross-section, normalized to the cross-sectional area (Qscat), and fraction of scattered light coupled into the substrate (Fsub) for a 120 nm diameter Ag hemisphere on GaAs substrate with varying thickness of TiO2 layer.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Normalized photoresponse of reference solar cell, reference solar cell with a back reflector and a plasmonic solar cell with 5 nm TiO2 spacer layer. (b) Photoresponse of the reference QD solar cell under front and rear illumination. Inset shows the illumination configuration.
