染料敏化太陽能電池立體結構設計與效率之研究

本研究設計出兩種不同的染料敏化太陽能電池結構，這兩種設計法的光陽極擁有立體的結構，分別為封閉式電池與開放式電池。其目的是使光電極薄膜的面積增加，在固定的照光面積下使受光面積提升，以達到提升光電轉換效率的目的。封閉式電池的設計思考方向是以此實驗來證明染料敏化太陽能電池在立體結構的基礎上是否成立，本實驗的製作方式是將5片氧化銦錫鍍膜導電玻璃疊合成光陽極結構，玻璃間距為300 μm；電解質使用液態電解質，對電極為厚度300 μm的導電銅箔，封裝方法是使用高度為10 mm至15 mm的壓克力薄片黏合而成的完整封裝，根據太陽光源模擬器機台實際量測後，量測曲線可以抵達電壓-電流坐標軸的第四象限，雖然光電轉換效率不佳，但也證實了實驗結果的可行性。開放式電池的設計是用以改良封閉式電池，它的製作方式很多元，主要是利用石墨紙、碳片和白金等對電極材料，再以不同尺寸做量測，電解質使用膠態電解質，封裝方式為簡易封裝。對電極材料為鉑薄膜應用於疊合式立體電池的實驗結果顯示，照光面積為0.28 cm2，電池高度為7 mm，可得開環電壓0.662 V、短路電流密度18.42 mA/cm2、填充因子0.31、光電轉換效率3.85%，為直立式立體電池的1.65倍，並為平板式電池的2.15倍。

This study designed two different dye-sensitized solar cell structures, these two design methods have a three-dimensional structure of the light anode, respectively closed and open cell battery. The aim is to increase the area of the photoelectrode film, in a fixed area of the illumination area of the light to enhance, improve photoelectric conversion efficiency in order to achieve the purpose. Consideration closed cell design experiments in order to prove that the direction the dye-sensitized solar cell on the basis of the three-dimensional structure is established, production methods of this experiment is to 5 of indium tin oxide coated conductive glass anode structure stack synthesized light, glass spacing to 300 μm; electrolyte using a liquid electrolyte, the counter electrode is a conductive foil thickness 300 μm, encapsulation method is to use a height of 10 mm to 15 mm acrylic sheet bonding together a complete package, according to the solar light simulator machine actual measurements, voltage measurement curve can be reached - Current fourth quadrant of the coordinate axes, although the photoelectric conversion efficiency is poor, but the feasibility of the experimental results confirmed. Open the battery are designed to improve Enclosed battery, its way of making a lot of dollars, mainly using graphite paper, carbon sink and counter electrode materials such as platinum, and then do measurements in different dimensions, electrolyte using colloidal electrolyte package method is simple package. Pt counter electrode material is laminated three-dimensional cell film applied experimental results show, according to the light-receiving area of 0.28 cm2, cell height of 7 mm, the open circuit voltage can be obtained 0.662 V, short circuit current density 18.42 mA/cm2, fill factor of 0.31, the photoelectric conversion efficiency 3.85%, for the three-dimensional vertical 1.65 times the battery and the battery is flat 2.15 times.
