title: Photoisomerization of the cyanoacrylic acid acceptor group--a potential problem for organic dyes in solar cells.
abstract: Organic solar cell dyes containing the most common anchoring group, cyanoacrylic acid, are shown to be photolabile and undergo photoisomerization. This may have significant consequences for dye-sensitized solar cells, as isomerisation competes with electron injection and leads to modifications of the dye and surface arrangement.
