Thiazolo [5, 4-d] thiazole-based organic sensitizers with strong visible light absorption for transparent, efficient and stable dye-sensitized solar cells
A small set of thiazolo [5, 4-d] thiazole-based D–π–A organic dyes, endowed with bis- pentylpropylenedioxythiophene (ProDOT) moieties in the π-spacer, was designed with the aid of computational analysis, synthesized and characterized. The presence of bulky and electronrich ProDOT groups beside the electron poor thiazolothiazole unit induced optimal physico-chemical properties, including broad and intense visible light absorption. As a ...
