TUNING ABSORPTION IN THE SOLAR SPECTRUM THROUGH A METALLIC SLIT ARRAY ON A FLEXIBLE SUBSTRATE
Аннотация
Solar absorbers based on optical metamaterials are usually designed and fabricated on a rigid substrate. Due to
its rigidness, such solar absorbers are limited to planar surfaces. In this study, we investigate the possibility of
a flexible solar absorber with nanoscale metallic slit arrays on a flexible polyethylene terephthalate substrate.
It is shown that the solar absorptance can be tuned from 0.1 to 0.6 by changing geometry of metallic slit
arrays.
