    • 量子點敏化太陽能電池元件的製備方法有許多種。在本研究中主要探討使用微波合成技術來進行硒化鎘量子點的合成並被覆二氧化鈦奈米粒子光陽極表面，藉此進行太陽能電池的研究。讓光陽極直接浸泡在反應的前驅物溶液中，藉由微波合成法的優點，快速提供分子所需動能，克服成長所需之活化能特性，加速反應進行合成，使量子點有效均勻被覆於光陽極上，並避免頂部堵塞的問題。
    在此研究中選用二氧化鈦奈米粒子構成光陽極，由於二氧化鈦奈米粒子具有較高的比表面積，因此可以沉積較多量子點。首先，探討反應時間對元件效率的影響。經實驗結果可知：每5分鐘更新反應溶液進行2次反應，具有較佳的效率表現，可達1.07 %。此外，結合連續離子式吸附反應法被覆上不同層數的硫化鎘和硫化鋅，其效率值達1.78 %。再藉由電化學阻抗頻譜分析法，配合適當的等效電路模型，可模擬分析電極的電荷傳遞機制，探討其效率提升的可能機制。
    而在對電極的使用上，以合成硫化物Co3S4進行對電極的製備。藉由量測電荷轉移阻值的分析可得知：Co3S4的對電極的電荷轉移阻值低於白金近乎20倍。將此對電極應用於量子點太陽能電池，因此使效率破2.72%。除此之外，在結構層上添加二氧化鈦微米球做散射層，光電轉換效率進而提升至2.92 %

    There are many kinds of methods to fabricate quantum dots sensitized solar cells (QDSSCs). In this study, microwave reactor was employed to synthesize cadmium selenide (CdSe) quantum dots directly on the surfaces of titanium dioxide nanoparticles (TiO2-NPs) photoanode for the study of solar cells. In the microwave method, the photoanode can immerse into the precursor solution directly and control the decoration of quantum dots by immersion time. Due to provide the necessary energy immediately by microwave irradiation, quantum sots can decorate on the surfaces of photoanode rapidly and avoid the agglomeration of quantum dots on top of photoanodes.
    In this work, TiO2-NPs were used as photoanodes due to their high specific surface areas. Firstly, we discuss the influence of reaction time on the performance of QDSSCs. From results, we can find the conversion efficiency of QDSSCs can arrive 1.02 % when the precursor solution was refreshed twice and each time was 5 min. In addition, the conversion efficiency can arrive 1.68 % when different layers of cadmium sulfide and zinc sulfide were decorated on the surfaces of photoanodes. The carrier transport properties of these types of QDSSCs can be resolved by using electrochemical impedance spectroscopy technique with suitable equivalent circuit model.
    As for the counter electrode, we also prepared Co3S4 electrodes to replace Pt electrodes in our QDSSCs. The performance of Co3S4 electrodes can be evaluated by measuring charge transport resistance. From measurement, we can find the charge transfer resistance of Co3S4 has improved around 20 times compared with Pt counter electrode. The efficiency of QDSSCs can arrive 2.72 %.Furthermore,we also add TiO2-MS scattering layer on photoandoes. The efficiency of QDSSCs can arrive 2.92%
