Hierarchical Nanostructures for Solar Cells - Hierarchical Nanostructures for Energy Devices - page 81

transport and recombination loss in terms of solar devices. 5 Understanding
the light absorption property, interface electronic band structure, and photo-
carrier dissociation and recombination are key issues to the overall per-
formance. 5 To establish a reliable structure-performance correlation, a wide
range of characterizations should be carried out in a consistent way. Overall,
these are multidisciplinary topics, for which physics and chemistry experi-
mentalists and theoreticians need to sit together and brainstorm innovative
ideas to bring great enhancement to solar cells and energy devices with
hierarchical nanostructures.
