摘要

染料敏化太陽能電池（Dye-sensitized solar cell，DSSC）由於製備成本便宜、元件技術穩定、光電轉換效能佳等特性，受到各界專家學者的重視，積極開發先進的功能性材料，使得DSSC之光電轉換效率由1991年的7%達到現今的14.3%，在微弱室內光源下更可高達28%，已達到能夠商業化之標準。染敏電池的長期穩定性亦有相當優異的表現，在不同的光照強度與角度下，皆能穩定且生生不息的產生潔淨的電能，透過染敏電池與「物聯網」之結合，將有助於達成低碳節能的目標。本章將針對DSSC中的各部分組成，包含半導體奈米材料、光敏染料、電解質、觸媒對電極等四大部份，分別探討其相關材料之合成設計與發展歷程。

Dye-sensitized solar cells (DSSCs) have caught a lot of attention due to the low cost, easy device fabrication with decent reproducibility, and good solar-to-electricity conversion efficiency. Many pioneer researchers devoted themselves to explore advanced functional materials in order to elevate the cell efficiency from the 7% in 1991 to the current 14.3%. At dim light illumination, the cell performance even reached higher as 28%, which is available for commercialization. Moreover, DSSCs possess good cell performance and long-term stability at variable incident light intensities and angles. Stably and continuously clean electricity would be generated by integrating DSSCs into the ＂Internet of Things,＂ and the carbon emission could be largely reduced. In this chapter, the design, synthesis and development of variable advanced functional materials used in high performance DSSCs were separately introduced, including semiconductor nano-materials, dye sensitizers, electrolytes, and catalytic electrodes.
