Dye-sensitized solar cells (DSSCs) are less expensive and easier to manufacture than silicon-based solar cells. Due to their superior catalytic characteristics and affordability, carbon materials can be used as counter electrodes in DSSCs instead of platinum electrode. Recently, CuSCN has been widely considered a promising candidate for low-cost and high-stable hole transport material in advanced solar cells. Herein, we report the design and fabrication of dye-sensitized solar cells using carbon-graphite counter electrode with combined solid-state based copper (I) thiocyanate (CuSCN). Lab synthesized TiO2 nanoparticle with size of ∼ 30 nm and carbon black-graphite composites (CG) paste were used for the all DSSCs device fabrication. The structural, morphological and compositional details were investigated using various characterization techniques. For construction of the efficient counter electrode, the conventional expensive platinum catalyst thin film was replaced by cost effective and stable solid-state based carbon-graphite-CuSCN layer. The conventional Pt and Au counter/back electrodes raise the overall fabrication cost of commercial DSSC devices. Due to the superior catalytic capacity, simple scaling, low cost, and long-term stability, carbon-based composite shows as a promising candidate for DSSCs. The newly developed carbon black-graphite composites with CuSCN counter electrode showed improving efficiency and stability of the DSSCs. The best conversion efficiency of 8.56% was achieved using a CG composite with CuSCN-based counter electrode under AM 1.5 solar condition.
