本研究採用模擬與實驗的方式進行熱電模組發電量之探討，由模擬結果得知晶粒高度越低時，熱電模組的發電量會隨之增大。配合實際封裝測試結果與模擬結果相互驗證，封裝測試結果與模擬結果兩者趨勢相同，但發電量增加比例卻比模擬得來的小，主要原因在於實際量測時，晶粒高度較低之模組，上下機板間之熱損失較嚴重。此外，在模組兩端溫差相同時，且受基板之影響，晶粒兩端之實際溫差較低所致。

The study uses simulation and experiment to investigate the power capacity of thermoelectric generator modules. The result shows that the power capacity increases with reducing the leg height. Compare with the results of simulation and packaging test, they have the same trend. However, the ratio of power capacity increases with leg height reduce in packaging test is smaller than them in simulation. In the packaging test, the main reason is that the heat loss between the top and bottom substrate is more serious in the shorter the legs. In addition, the shorter legs have the lower temperature difference that influence by the substrate at the same temperature difference between two ends of the module.
