THERMOPHOTOVOLTAIC EFFICIENCY ENHANCEMENT THROUGH METAMATERIAL SELECTIVE EMITTERS

摘要

Applying thermophotovoltaics (TPV) to present energy production technologies allows us to increaseenergy output while utilizing existing infrastructure by reclaiming the heat lost during the production process. In order tomaximize the efficiency of these sources, the conversion efficiency of the TPV system needs to be optimized. Usingmetamaterials, we have created selective emitters that tailor the incident light spectrum to the band gap of specific diodes,offering the potential to reduce diode heating and increase efficiency. Usage of metals such as platinum and molybdenummakes the emitters able to withstand the high temperatures required to create ideal spectra for III-V cells. Simulationsfrom CST Microwave Studio were used in the design process and testing of the emitters includes heat tests and SEManalysis.
