Counter Electrodes in DSSCs Based on Carbon Derived from Edible Sources

Summary

Carbon is a part of all life forms and organic matter. Carbon exists in a wide range of crystalline allotropes and amorphous forms. Dye‐sensitized solar cells (DSSCs) have attracted much attention due to their moderate energy conversion efficiency, low cost, environmental friendliness, and simple fabrication procedure. This chapter presents a compilation of results on DSSCs prepared with counter electrodes (CE) based on carbon materials derived from sucrose, glucose, and sugar free. Carbon derived from edible precursors has been used to fabricate the CE for DSSCs. The field emission gun scanning electron microscopy (FEG‐SEM) images of carbon derived from soluble sources. Cyclic voltammograms (CV) of the carbon derived from edible precursors and Pt counter electrode. Carbon‐based materials provide large effective surface areas due to their porous or rough morphology, leading to a large number of reduction sites and hence low charge transfer resistance.
