以熔射塗層方式製作染料敏化太陽能電池

Abstract

敏化太陽能電池(DSSC)是第三代發展的太陽能電池，其製程簡單、成本低廉、且具有多種顏色變化，甚至可製作成具有可撓曲的特性，具有很多一般太陽能電池所沒有的特性。而熱熔射(Thermal Spray)技術發展至今也已有百年的歷史，且此技術也朝著各個不同的領域展開應用，不論是傳統產業、電子業甚至航太業處處都可看到熱熔射(Thermal Spray)技術的使用。以熱熔射(Thermal Spray)製程可以製作出具有非常高的表面積，非常適合用於表面積需求高的應用。本論文內會介紹DSSC的原理、製作方式以及熱熔射(Thermal Spray)的原理與製作方式，並探討使用熱熔射(Thermal Spray)製程所製作的Ti層是否可以在其3D的結構上利用陽極處理長出TiO2 nanotube結構，並以此作為DSSC的陽極探討其可行性。根據實驗規劃測試結果顯示，以這樣的結構所製作的DSSC元件的光電轉換效率可達2.18 %。

A dye-sensitized solar cell (DSSC) is a third generation solar cell, and it owns a lot of characteristics such as easy fabrication, low cost, colorful expression and flexibility. Thermal Spray technology has been developed for hundreds of years, and applied to various fields, such as conventional industries, electronics industries and aerospace industries. The thermal spray process which can produce high surface area products suits to high surface area demand. The fabrication and characterization of DSSC devices prepared by thermal spray process are discussed in this thesis. The three-dimensional TiO2 nanotube(TNT) structure was successfully grown on the mesoporous Ti layers fabricated by thermal spray process, and served as photoanode materials for a TNT based DSSC. The cell performance of the TNT-DSSC shows an overall power conversion efficiency η=2.18%.
