論文名稱: 微型燃燒驅動式熱光電系統之概念、設計與示範 / Concept, Design, and Demonstration of the Combustion-Driven Micro-Thermophotovoltaic Power System
中文摘要:
本研究開發體積小、能量密度高的燃燒驅動式微型熱光電（TPV）發電系統。針對微尺度燃燒的熱損失、壁面冷熄與滯留時間過短等問題，設計以白金觸媒管與石英管組成的燃燒器，並以穿孔白金管搭配背向階梯穩焰，擴大穩定操作範圍。透明石英管可將火焰與觸媒的輻射一併導入光電池；管內壁披覆氧化鐵層作為輻射器，比碳化矽更易加熱至白熾狀態。研究結合基礎實驗與數值模擬，採用GaSb光電池，以積分球量測輻射，並組裝完整原型以評估整體效率。
英文摘要:
This thesis develops a micro-scale combustion-driven thermophotovoltaic (TPV) power system, a solid-state device that converts thermal energy directly into electricity. A combustor serving as the emitter is built around a platinum catalyst tube and a quartz tube, using a perforated platinum tube and a backward-facing step to stabilize the flame and widen the stable operating range despite heat loss and radical quenching at small scale. The transparent quartz tube lets radiation from both the flame and the catalyst reach the cells, and an iron-oxide coating inside the tube is explored as an emitter that heats to incandescence faster than SiC. GaSb photovoltaic cells are used for conversion, an integrating sphere measures the radiant output, and a TPV reactor with a cell array is assembled to determine the overall efficiency.
