Abstract Two design elements for donor-acceptor organic dyes used in dye-sensitized solar cells (DSSCs) are presented. 4-(Cyanomethyl)benzoic acid was used as an acceptor group and was compared to the commonly used cyanoacrylic acid acceptor group in a pair of otherwise structurally equivalent sensitizers. The 4-(cyanomethyl)benzoic acid based dyes showed significantly improved photovoltaic performance when tested in DSSCs. Furthermore, it was shown that the replacement of the bridging para… CONTINUE READING
