摘要
近年来,可再生资源特别是太阳能的有效利用逐渐成为人们关注的焦点。设计合成新型的有机敏化染料是提高太阳能电池转化效率的重要手段。我们设计合成了四种以二茂铁为电子给体,以苯、噻吩、咔唑和吩噻嗪为桥连基团,以氰基乙酸为电子受体的D-π-A型有机敏化染料。研究了四种染料的光物理和电化学性质,并将其应用在染料敏化太阳能电池中考察了其敏化性能。
Dye-sensitized solar cells(DSSCs) is one of the most prospective and potential photovoltaic devices to deal with environmental issues and energy crisis. Dye sensitizer plays a key role in absorbing the sunlight and separating charges in DSSCs. Four organic D-π-A dye sensitizers, which ethynylferrocene substituted benzene, thiophene, carbazole and phenothiazine unit act as donors and cyanoacetic acid act as acceptor, were synthesized via Sonogashira coupling and Knoevenagel condensation reactions. The photophysical properties and photovoltatic efficiency of dyes were studied.
