  Recently,the field of small-molecule-based OPV cells has seen a major thrust towards development of new materials with tunable structures and facile synthesis.[1,2] A series of squaraine dyes form a notable class of OPV cells because of their high absorption coefficients of greater than 2×105 cm-1 and intense absorption in the near infrared region.These absorption coefficients are found to be dependent on morphology.
