Molecular design and understanding the structure–property relationship of π-conjugated spacer play pivotal roles in realization of considerable enhancement performance of dye-sensitized solar cells (DSSCs). Three triphenylmaine dyes, namely MX11-13, have been designed and synthesized, which incorporate 2,2,6,6-tetramethylbenzo[1,2-d;4,5-d′]bis[1,3]dioxole (TMBD), phenyl and 1,4-dipropoxybenzene (DPB)
分子设计和理解π共轭间隔基的结构-性质关系在实现染料敏化太阳能电池(DSSC)的显着增强性能方面起着关键作用。已经设计和合成了三种三苯基ma染料,即MX11-13,它们掺入了2,2,6,6-四甲基苯并[1,2- d ; 4,5- d ']双[1,3]二恶唑(TMBD)分别为苯基和1,4-二丙氧基苯(DPB)作为π共轭间隔基。研究了烷氧基取代基对染料敏化太阳能电池的光物理,电化学特性和性能的影响。对于典型设备,基于MX13的电池可提供整体功率转换效率(η)7.02%,与短路光电流密度(Ĵ SC),开路电压(V OC)和填充因子(FF的15.5毫安厘米)-2,697毫伏和0.65,分别。
