    • 本研究探討分兩部分，第一部份量子點敏化太陽能電池，分析以一步合成之Cdx:CuInS2量子點之光電性質，且將高量子產率的量子點作為光敏化劑應用在太陽能電池上。第二部份為染料敏化太陽能電池，欲使電池具發展性，必須改變背電極的性質，而背電極所須具備的條件為高催化活性和高導電性，本實驗室以一步合成合成相對於Pt具高光電轉換效率的CoxSe背電極，是可取代白金的背電極材料，本研究以電化學方法量測分析，比較背電極的優劣性質。

    第一部分:
    使用預先合成法(Pre-synthesis)合成Cd:CuInS2，改變前驅物的比例與反應時間，探討量子點之光學性質及電化學性質。使用UV, PL分析量子點之光學性質，CV量測量子點的能隙，再結合共敏化效應的概念，比較Cd:CuInS2與Cd:CuInS2/CdSe(4)兩電池之光電轉換效率。

    第二部分:
    為了使染料敏化太陽能電池具發展性，本研究改變背電極的性質取代昂貴的白金，採用水熱法一步合成硒化鈷(CoxSe)、硒化鎳(NixSe)、硒化銅(CuxSe)背電極，CoxSe背電極光電轉換效率可達6.53 % 超過白金效率，且CoxSe具高催化性、低成本之優點，極具經濟效益。使用SEM, EDS, EIS, Tafel, CV, J-V curve分析背電極材料之結構、界面性質和光電轉換效率。

    In this study, our research focused on two parts. The first part is quantum dot sensitized solar cell (QDSSC) and the second part is dye sensitized solar cells (DSCs). In the first part, we synthesized Cdx:CuInS2 quaternary QDs using a one-pot non-injection approach of alloying CuInS2 with Cd2+. Synthesized high quantum yield QDs optical and electrical properties were analyzed by applying them QDs to solar cell application and cyclic voltaic (CV) measurement. We used UVPL and CV to measure photoluminescence, band gap of QDs respectively. The combined co-sensitization’s concept were used to compare Cd:CIS and Cd:CIS/CdSe(4) QDs photoelectric conversion efficiency (PCE) 1.70 % and 2.86 %, respectively.
    In other part, we present a facile one step hydrothermal approach for in situ growth of metal selenides on FTO glass. In this part, electrochemical analysis was employed to understand dynamic behavior of metal selenides and Pt counter electrode. In order efficiency development of counter electrodes and replacement of expensive platinum in DSSC, we used a facile one step hydrothermal method to synthesize CoxSe, NixSe and CuxSe counter electrodes. A maximum energy conversion efficiency of 6.53 % was obtained under AM1.5G simulated solar light for the cell fabricated with CoxSe as the counter electrode, which is better than Pt. So Pt can be replaced by cobalt selenide as counter electrode (CE) since it has higher PCE than platinum (Pt). The resulted CoxSe can perform better catalytic activity and low-cost requirement. We used SEM, EDS, EIS, Tafel, CV, J-V curve to analyze counter electrode’s structure, interface characteristic and PCE.
