染料敏化太陽能電池是一種製程簡單、具有可撓性、成本低廉的一種新型薄膜太陽能電池。近年來國際能源議題備受重視，使得國內外有諸多研究團隊針對染料敏化太陽能電池投入研究。染料敏化太陽能電池結構主要分成二氧化鈦工作電極、染料、電解質和白金對電極所組成，其中白金材料成本高昂且稀有，導致染料敏化太陽能電池整體商業化發展不易。
本研究分為三個部分，首先我們以聚苯胺材料作為染料敏化太陽能電池的對電極材料，並藉由加入改質材料與氧化石墨烯提升對電極的特性。本研究以FESEM分析電極的表面形貌、以AFM分析薄膜表面粗糙度、以EDS了解元素組成、以XRD分析結晶相位、以CV探討電化學特性，並將其製作成元件，探討元件的光電轉換效率、元件阻抗和外部量子效率。
其次，本研究製作N-type氧化亞銅工作電極，分析其薄膜表面形貌、元素組成、以及電化學特性。接著結合N-type氧化亞銅工作電極與白金對電極，製作成太陽能電池，並分析元件的光電轉換效率。
最後，本研究以二硫化鎢與白金製作染料敏化太陽能電池對電極，以FESEM分析電極的表面形貌、以EDS測量元素組成、以XPS觀察材料特性、以CV分析電化學特性，並將其製作成染料敏化太陽能電池元件，並分析元件的光電轉換效率、阻抗頻譜、以及外部量子效率。

Dye-Sensitized Solar Cells (DSSCs) have attracted much attention due to their various merits, such as high efficiencies, simple device structures, easy fabrication, and low cost. These features have made DSSCs attractive for solar energy applications in the face of increasing energy and environmental challenges. A typical DSSC consists of a transparent conductive substrate, a porous thin-film photoelectrode composed of TiO2 nanoparticles, dyes, an electrolyte, and a counter electrode (CEs). However, Pt is a rare and expensive metal element and may limit the DSSC applications.
This study was divided into three parts. Firstly, we used polyaniline as the counter electrode material of dye-sensitized solar cells, and improved the characteristics of the counter electrode by adding modified materials and graphene oxide. FESEM was used to analyze the surface morphology of the electrode, AFM was used to analyze the surface roughness of the film, EDS was used to investigate the elemental composition, XRD was used to analyze the crystal phase of the materials, and CV was used to investigate the electrochemical characteristics. Then, the photoelectric conversion efficiency, electrochemical impedance, and external quantum efficiency of the DSSCs were investigated.
Secondly, the N-type Cu2O working electrode was fabricated, and its surface morphology, elemental composition, and electrochemical characteristics were analyzed. Then, the working electrode of Cu2O and platinum counter electrode were combined to fabricate a solar cell, and the photoelectric conversion efficiency of the solar cell was analyzed.
Finally, the dye-sensitized solar cell counter electrode was made of WS2 and platinum, the surface morphology of the electrode was analyzed by FESEM, the elemental composition was measured by EDS, the material was observed by XPS, and the electrochemical characteristics were analyzed by CV. The photoelectric conversion efficiency, the impedance spectrum, and the external quantum efficiency of the dye-sensitized solar cells were analyzed.
