Description:: Renewable energy technology, more so than ever before, is critical to the survival of humanity. For decades, concentrated efforts into designing and developing such novel devices resulted in the innovation of solar-driven photovoltaics that were competitive with nonrenewable alternatives. This thesis explores the dynamic behavior of alternative material candidates that...

Description:: Recent progress in the field of nanomaterials has enabled significant advances in optoelectronic devices such as solar cells, light-emitting diodes, photocatalysts, and sensors. Nanoparticles feature superior optical and electronic properties that arise from quantum confinement and therefore cannot be attained used bulk materials. However, further developments in the field of...

Description:: Halide perovskites, AMX3 (A = monocation, B = Ge, Sn, or Pb, and X = halogen), present a versatile class of solution-processable semiconductors made from earth abundant materials with outstanding electrical and optical properties. Their solar cell efficiencies have dramatically increased from ~9% to ~22% in less than five years...
