Since their inception by Gratzel, M., O'Regan B. and et al. dye sensitized solar cells (DSSCs) have shown much promise in the solar energy sector. The most glaring advantage is their ability to surpass the so called Shockley-Queisser limit through implementing a tandem design. The advantageous traits are not limited to the potential efficiency, but include ease of large-scale manufacture and low impurity sensitivity. The open circuit voltage (Voc) and short circuit current (Jsc) are two factors that contribute to the overall efficiency determination of a DSSC. In individual p- and n-type DSSCs, the maximum Voc obtainable is the difference between the fermi-level of the conducting oxide and the redox potential of the electrolyte. Thus, the Voc is tunable by using different electrolytes and/or different semiconductors.
