Natural structure with simultaneous negative permittivity and permeability has not been discovered yet. However, using specially-designed metal embedded in dielectric bodies can achieve a kind of artificial negative index. This periodic structure which is smaller than the guided wavelength is known as a metamaterial. However, recent designs of metamaterials have some disadvantages when they are used in the application of solar cell. The perfect absorption is only within a narrow band, and for most of the solar spectrum, the absorption is no more than 10%. Here, a new kind of absorber for the solar spectrum has been designed and analyzed, …

- Build a model of spiral nanoantenna and an antenna
array based solar cell collector. - Using Rao-Wilton-Glisson (RWG) basis functions to
simulate the spiral nanoantennas. - We calculate the frequency response of the radiation
gain as the indicator of receiving bandwidth which is a
key factor in conversion efficiency.

The Problem
• Photovoltaic output power can be affected by many factors including clouds passing overhead.
• Utilities in generally prefer a guaranteed power delivery level over some specified power delivery period.
• Power delivered during peak demand hours is generally more valued by utilities. For the Desert Southwest this is in the summertime afternoons. For the local area this will be defined as 1-5 pm for the three summer months.
• While battery power can be adapted to this problem, large batteries to be expensive.
