Polymer / Transparent Electrode Interface Studies with Applications for Organic Solar Cells
(2014-02-24)
The field of organic photovoltaics continues to progress through a combination of improved materials selection and a deeper understanding of operational mechanisms. We contribute to advances in both areas through study of the interface between the semiconducting polymer and the transparent electrode. This interface is the ...
Adsorption and Thin-Film Adhesion on Single-Crystalline Surfaces: Enthalpies, Entropies, and Kinetic Prefactors for Surface Reactions
(2014-02-24)
Chemical bonding at solid surfaces and interfaces is influential in a wide range of important technological applications including catalysis, fuel cells, batteries, chemical sensors, and device fabrication for microelectronics, computers, solar cells, and all variety of coatings. Adsorption and adhesion energetics are key ...
Photodoping of Colloidal Nanocrystals
(2014-04-30)
This dissertation addresses various aspects of photodoping colloidal nanocrystals. Photodoped ZnO nanocrystals were found to be versatile tuneable reducers using both quantum confinement and band-gap engineering with Mg2+ doping to change the conduction band potential. Using photoluminescence of the visible trap and magnetic ...
