The solid state dye-sensitized saolrc cells (DSSCs) employing polymer electrolytes show high overall energy conversion efficiency as high as 4.5% at 1 sun conditions. The improved efficiency may be primarily due to the enlarged interfacial contact area between the electrolyte and dyes in addition to the increased ionic conductivity, which were done by utilizing liquid oligomers, followed by in situ self-solidification, to form the solid DSSCs "Oligomer Approach". The effect of the charge transfer resistance at the counter electrode side on the effciency has also been investigated.
