Nanostructures for Enhanced Light Absorption in Solar Energy Devices
Figure 6
(a) Absorbance spectra recorded for different carbon structures. Nanostructured HOPG corresponds to inset micrograph. Rough HOPG corresponds to a surface like the one observed between the nanoparticles in the inset. (b) Graphite nanostructures fabricated on HOPG with HCL and reactive O-plasma etching.
