本次論文中，我們主要對於混合式多重量子井結構做探討，透過混和不同鋁含量的短週期量子井結構，觀察其對於發光元件與光伏元件的特性分析。
首先量測基本發光元件特性，透過積分球量測元件的光輸出功率與發光波長，利用公式計算其外部量子效率與效率衰減，本實驗中，在100mA下，其啟動電壓約有0.08V的增加，而其發光效率與一般標準發光元件相比有11.7%的提升。
而太陽能電池部份量測，此部分包含量測不同照光倍率下的元件特性，並使用可外加偏壓的外部量子效率量測系統，量測特定偏壓點下的光波長轉換效率的變化，本次元件在1倍太陽下，其效率具有28.1%的提升。
最後本論文使用台大光電所吳育任教授所製作的模擬軟體來模擬元件在不同偏壓下的能帶與載子分佈，並透過模擬和文獻來分析發光元件與光伏元件所量測的特性，本次實驗結果與分析將於本論文中詳細描述。

In this study, we focused on hybrid multiple quantum wells(MQWs) structure which used in light emitting diodes (LEDs) and solar cells.
The hybrid Al0.1GaN/ InGaN and GaN/ InGaN MQWs structure we named it SCIII. And the hybrid Al0.06GaN/ InGaN and GaN/ InGaN MQWs structure we named it SCII.
First, we compared the optoelectronic of light emitting diodes. At 100mA current injections, the output power were 77.6, 74.5 and 68.6 mW for SCIII, SCII and conventional structure. The efficient of the best LED is SCIII structure, which have 11.7% enhanced.
Then, we measured the different concentrations of Sun to compare the property of solar cells in different structures. We have significantly improved in fill factor (FF%) . The FF% in one Sun were 70.4% , 59.7% and 54.6% for SCIII , SCII and conventional structure .
In the end, we used the numerical simulation by One Dimensional Poisson, Drift-Diffusion, and Schrodinger Solver (1D-DDCC) which development by professor Yuh-Renn Wu. By using the simulation, we according the band diagram and carrier distribution to know the reason that component have better optoelectronic. The more details would be discussed in this thesis.
