本研究主要分爲實驗與模擬相互驗證，以及結構優化設計：首先於實驗中給予鈣鈦礦發光二極體樣品穩定電源，並量測其溫度，後透過軟體建立樣品模型，並在相同條件下進行模擬，隨後比對兩者結果以驗證模擬模型之準確度；其次是結構優化設計，本研究提出了三種措施，包含：1) 對電極的間距進行調整；2) 於模型中加入電子與電洞傳輸層；3) 變更模型電極之材料，並模擬分析上述不同方案對於鈣鈦礦LED元件的散熱性能影響。
;Perovskite has received much attention in the semiconductor industry because of its excellent optical properties. One of the applications of this material is the perovskite light-emitting diode (PeLED). Compared with other common light-emitting diodes (LED), PeLED has plenty of advantages, such as compatibility with solution process lower price. However, there are still many deficiencies in PeLED in current stage. The heat generation during the working process may affect its performance and lifetime. Therefore, this study will focus on the thermal characteristics of the PeLED.
In this thesis, a thermal simulation model of PeLED had been constructed in the simulation software, COMSOL. Also, the model has been compared with the experiments of the PeLED sample. After the verification, improved the thermal performance of PeLED was improved by adjusting the structure and materials in the model. Through the simulation, the performance of each measure on the improvement of heat dissipation was verified.
This research is mainly divided into two parts: the verification of the model through the comparisons with experiments and the simulation of the proposed measures with different structures and materials. In the experiment, a stable power was provided to a PeLED sample, and then its temperature was measured with a thermocouple. In the simulation, the sample model was established in the software under the conditions agreeing with the experiment. Compared with the experimental results, the simulation results have showed the acceptable accuracy. The second part was to change the structures and materials of the PeLED in the verified model for improving its thermal performance. Three measures, including: 1) adjusting the spacing between electrodes, 2) adding electron transfer layer and hole transfer layer to the device, and 3) using different electrode materials are proposed and simulated in this study. The analyses of the heat dissipation performance of the PeLED for every measure are discussed in this thesis.
