Image of FIG. 1.
FIG. 1.

(Color online) Spatial photoluminescence intensity contour maps over the surface of a five-layer QD array for emission wavelengths of (a) and (b) under laser excitation. (c) A representative atomic force microscopy image of the MOVPE grown InAs QDs. (d) The normalized PL intensity vs position across the PL map shown in (a) black circles and in (b) red triangles, and (e) the corresponding average PL intensities plotted with respect to fluence.

Image of FIG. 2.
FIG. 2.

(Color online) Spectral response vs wavelength for the reference (black circle), QD1 (blue squares), and QD5 (red triangles) at (a) beginning of life (BOL) and (b) post . The insets contain log plots of the spectral response from . (c) Spectral response normalized to BOL vs fluence at 910 and corresponding to the InAs QD and GaAs response peaks, respectively.

Image of FIG. 3.
FIG. 3.

(Color online) Open circuit voltage , short circuit current density , and maximum power with respect to fluence for the reference pin device (black circles), the one-layer InAs QD pin device (blue squares), and the five-layer InAs QD pin device (red triangles). The inset contains the beginning of life characteristics of the devices under simulated air mass 1.5 illumination. (The lines are provided as visual aids to guide the eye.)
