Surface interactions of half-squaraine dyes in dye-sensitized solar cells

This paper presents a summary of our recent work on half-squaraine dyes for use as sensitizers in dye-sensitized solar cells. Our data include a review of the highest efficiency half-squaraine dyes to date. The discussion also considers how Jsc varies with functionalization of the Hf-SQ dyes and how these modifications affect device lifetime. The paper also discusses recent papers which consider the influences of the position and number of carboxylate linker groups on the chromophore.
