Dye molecule bonded titanium alkoxide: a possible new type of dye for sensitized solar cells†
Abstract
An organic dye coordinated titanium iso-propoxide compound is designed and synthesized. Taking advantage of the hydrolysis of the titanium alkoxide moiety on the surface of TiO2 electrode, the dye–semiconductor surface properties, including anchoring and dispersivity, are improved, which opens a new perspective to explore dyes for DSSCs.
