Double D--A Branched Dyes — A New Class of Metal-Free Organic Dyes for Efficient Dye-Sensitized Solar Cells

Abstract

Double branched donor acceptor compounds (D--A)2L, whose separate branches are linked by saturated chains or ring systems, are highly promising sensitizers for dye-sensitized solar cells (DSSCs). Their photovoltaic performance  (power conversion efficiency PCE) is higher than the  value of the corresponding single branched sensitizers D--A. The advantage can be attributed to the lower aggregation tendency and to the higher loading density of the chromophores on the semi-conductor surface (TiO2). Moreover, the intramolecular transfer of the excitation energy can enhance the contact time of the adsorbed dye molecules in the excited state S1 and thus reduce the unwanted charge recombination (dark current).
