Solar Cell Design Using Metamaterials, Yang Liu, Yitung Chen, Jichun Li

College of Engineering: Graduate Celebration Programs

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, …

A Computation Model For Nanoantenna-Based Solar Cell With High Conversion Efficiency, Yiyan Li, Ke-Xun Sun, Yingtao Jiang

College of Engineering: Graduate Celebration Programs

• 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.

Investigating Perspectives Of Rural Nevadans On Climate Change Solutions, Tricia Dutcher

Graduate Research Symposium (GCUA) (2010 - 2017)

Rural perspectives are important for the issue of climate change. Rural areas are high concentrations of active voters who deny the problem of anthropogenic climate change. Rural residents also face decisions about inviting large, utility scale renewable energy developments in their areas. This research examines rural Nevadan’s perspectives on climate change to offer insights about the relationship between climate change perceptions and communication strategies. The research offers policy implications that address context specific issues, solution-oriented dialogue, and interest matching to mitigate anthropogenic climate change.
