Graphene a wonder material is a single layer of graphite and a carbon allotrope is a plentiful mineral on Earth. Graphene and its derivatives such as rGO, GO and pristine graphene, etc., when used as composites with TiO2 semi-oxide material exhibited an improvement in PCE in Michael Grätzel and Brian O’Regans DSSCs from ~ 0.13% to above 12%. Graphene has unique properties, which make it more reliable than silicon solar cells and thin film solar cells, with the advantage of low cost, low toxicity, simple manufacturing techniques, flexibility, and extremely lightweight. They have a large specific surface area, transparency, electron mobility, and superior stability. Nature supplies a huge variety of putative structures for photosensitizers and combination may enhance stability, efficiencies, and sustainability. This review paper discusses a recent development reported in DSSCs when Anthocyanin Sensitizers with Graphene derivatives are used as photoanodes. Anthocyanin pigment is water-soluble and highly dependent on its pH value. If its pH value changes, then its appearance also changes. They have an absorption range between visible and ultraviolet spectra. Composites absorbed in Anthocyanin natural dyes show a favorable increase in charge transfer or conductivity of the cell. Moreover, the incorporation of Anthocyanin-based DSSCs has shown a much better power conversion efficiency (PCE) than the chlorophyll-based DSSCs.
