Development of a D–π–A dye with benzothienopyridine as the electron-withdrawing anchoring group for dye-sensitized solar cells†
Abstract
A D–π–A dye SAT-1 with benzo[4,5]thieno[2,3-c]pyridine as the electron-withdrawing anchoring group capable of forming a hydrogen bond at Brønsted acid sites or a coordinate bond at Lewis acid sites on a TiO2 surface has been developed as a new-type of D–π–A dye sensitizer for dye-sensitized solar cells.
