摘要

染料敏化太陽能電池其構造為兩片導電玻璃、奈米多孔性TiO_2、染料及電解質等，其光電轉換效率已可達到10%。而其中電解質扮演著重要的角色，不僅牽涉到電池的高性能或穩定性問題，甚至成為商品量產化的重要關鍵之一。本文將介紹有機凝膠的基本特性以及如何形成凝膠電解質並應用在染料敏化太陽能電池上。

The combination of nanoporous TiO_2 photoanode with a monomolecular layer of an appropriate dye photosensitizer has led to the development of dye-sensitized solar cells (DSSCs) capable of up to 10% solar energy conversion efficiencies. However, DSSCs based on liquid electrolytes potentially suffer a number of problems such as the leakage and volatilization of the liquid, possible desorption and photodegradation of the adsorbed dyes, and the corrosion of the Pt counter electrode, and the consequence is the ultimate limit on the long-term stability and overall performance of these DSSCs. Very recently, several so-called quasi-solid-state DSSCs have been reported to preserve the advantage of similar ionic conductivities of liquid cells and at the same time have the mechanical properties similar to those of solid cells. In this article, we will briefly introduce the basic properties of gel materials and their utilization as gel electrolytes in DSSCs.
