Since the adsorption of alkali metals is necessary for the negative electron affinity (NEA) of
the photocathode, light absorption models of GaN nanowire (NW) arrays with alkali metal …

Solar cells as a light-electricity conversion device, light absorption plays crucial role towards
their high performance conversion. Incorporation of plasmonic nanostructures with …

Near field optics concepts have introduced a paradigm shift in a wide variety of engineering
fields in the recent past and the most significant applications of this fundamental physics …

Photovoltaics (PV) is a rapidly growing electricity source and new PV technologies are
continually being developed. Increasing the efficiency of PV will continue to drive down the …

Random textures are proved to be better for energy harvesting in solar cells. In this research,
we have studied the absorption properties of a random dielectric medium with plasmonic …
