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

Thin-Film Fabrication For High Pressure Thermoelectric And Electrical Resistivity Studies, Jorge L. Reynaga, Rama Venkat, Ravhi S. Kumar
Festival of Communities: UG Symposium (Posters)
Thermoelectric materials are of interest for application such as thermoelectric cooler in microprocessors and power generators in cars. High pressure plays an important role in understanding the changes in the figure of merit of thermoelectric thin films. To study the thermoelectric thin films a direct approach is to fabricate the thin film on the surface of a diamond anvil, so that the pressure dependence of structure and transport properties can be investigated easily. If we could successfully fabricate the electrical probes by depositing thin films, then it reduces the use of electrical wires as probes inside the diamond cell, as …
