本研究針對熱電模組開發出新式的量測方法，斜率量測法。有別於以往量測熱電模組的方法，斜率量測法以簡單的手法即可獲得熱電模組性能參數，如Seebeck coefficient、Internal resistance、Thermal conductivity等。對於熱電模組這三個性能參數最為重要，當獲得此三個參數後，可再透過數學關係式求得模組輸出功率、發電效率等。
斜率量測法是以Peltier effect做為量測依據的一個嶄新方法；量測開始，將會提供模組一微小定電流(小於1A)，輸入電流後的模組產生Peltier effect而模組兩端溫差開始加大，量測輸入電流後模組兩端跨壓與溫差，此兩者關係近似直線，將此兩者實驗結果做出擬合曲線再進行分析，可以發現此線段之斜率等於Seebeck coefficient，因此我們稱此方法為斜率量測法(SLOPE METHOD)。
本研究所發展之量測方法單次量測實驗耗時約2分鐘，與傳統以Seebeck effect做為量測依據的量測法動輒需要半個小時相比，節省了多數的時間，因此可以大量累積量測數據進行整理。與多數人常用的Harman Method相比，雖然時間上耗時相當，但斜率量測法使用了簡單的量測儀器即可獲得模組多數的性能參數，因此相較之下亦具有其競爭力。
斜率量測法量測結果為模組材料特性，無法直接獲得模組發電時的輸出功率、效率等，因此我們將量測結果代入軟體ANSYS分析，可簡單迅速的獲得模組輸出效能。
透過斜率量測法與分析軟體的搭配，可迅速獲得模組的實際發電效率與運作效能。快速量測的優勢使得工業使用、學術研究等更為方便簡單，亦可大量累積量測數據，增加量測結果的可信度。

This study presents a novel method, SLOPE METHOD, to determine the representative properties of a thermoelectric module. Different from other measuring methods, slope method can easily obtain the parameters like Seebeck coefficient, Internal resistance, Thermal conductivity. The parameters which could determine the efficiency of thermoelectric module are important. By using these three parameters, we can obtain power output, efficiency, and so on.
Applying a constant current to a thermoelectric module then measuring the module's transient voltage and both sides temperatures, the relation between voltage and temperature difference could be used to obtain a fitting curve, the slope of the curve equals to Seebeck coefficient, so we can rapidly determine the module's effective properties.
Comparing to the traditional measuring method which based on Seebeck effect, slope method spent less time about 2 minutes, so it could save lots of experiment time. Other like Harman method can obtain the figure of merit of thermoelectric module rapidly, but it should cooperate with other experiments if we want other parameters. This shows that the slope method have some advantage different from Harman method.
Slope method can’t obtain the power output directly while thermoelectric module using for power generating. Because of this reason, we use the software called ANSYS to simulate the real working conditions. We put the parameters obtained from slope method into ANSYS, and we can get the power output and efficiency easily. By using slope method and software, we could predict the performance easily, rapidly and accurately.
