摘要:	當人們追求生活進步和提高生活品質時，無形中消耗許多能源，造成能源枯竭，另外也附帶了許多環境汙染等問題。為了人類文明的永續發展，首當其充的是先解決能源殆盡的問題和提升保護地球的意識。於是擁有源源不絕的能源和零污染等優勢的太陽能受到了矚目。太陽能電池中的染料敏化太陽能電池由1991 年發展至今，科學家積極在研發和設計新穎的染料，而今最著名的染料為N719，希望可以發展出更高光電轉換效率的染料。而本文將試著以N719 染料為模板，參照實驗室的經驗，利用Imidazole 取代N719 的配位基，並在Imidazole 官能基上做修飾，期望能提高電池的轉換效率。 When people are pursuit of advances and comfortable life, sometimes ignore the imperceptibly consumes of energy, resulting in energy depletion. For the sustainable development of civilization, people have to solve the problem about energy exhausted and increasing the environmental awareness. Dye sensitized Solar Cells were developed since 1991. Recently, scientists are working hard in the development of the new generation dyes in order to having the higher conversion efficiency than the famous dye, N719. In this paper, according to our previous experience in the synthesis of N-heterocyclic carbene based sensitizers. We design the benzimidazole and its derivatives to modify our dye, CB113 and CB114. Hope this change can enhance the absorption of the dye and increase the battery's effeciency.
