Inorganic complexes as photosensitizers for dye sensitized solar cells (DSSC) are a widely explored area of research. A class of dyes is based on cis-Bis(isothiocyanato) bis(2,2'-bipyridyl-4,4'-dicarboxylato ruthenium(II) also known as N3 dye which has been popularized by Gratzel and others. While many research programs focus on expanding the region of the solar spectrum absorbed by the dye, there are several new approaches to advancing other limitations in DSSC's. We have been exploring the introduction of solid state electrolyte's to this end. An important chemical challenge involves interaction between the excited dye and the hole transport layer. By introducing organic ligands which act as a monomer for polymerization, we seek to introduce more rapid electron hole separation. Here we present the synthesis and characterization of a dye-hole conducting layer copolymer to enhance the hole transport at a polyethylene dioxothiophene transport layer.
