The continuous supply of energy is posing an increasingly major problem as the worlds population continues to grow and the cities become more industrialized. Therefore, for a sustainable energy supply chain, the humanity needs to focus its attention on sources other than fossil fuels, which is rapidly drying out. One of the promising alternatives is the solar power which can be harnessed via solar cells to generate electricity. The Dye sensitized solar cells (DSSCs) are an exciting form to generate electricity. In such solar cells, a light absorbing material anchored on a charge extracting material absorbs light and generates charge carriers creating an electric current, which is extracted via an external circuit. By far the most research charge extracting material as a photoanode in the cell is TiO2 because of well-known properties such as low toxicity, high stability, high efficiency for charge extraction, and its abundance. Carbon nanomaterials are heavily used in solar cell research due to their outstanding electrical characteristics, incredible mechanical and chemical stability, and higher  specific surface area. In this review, the incorporation of and contribution of carbon nanotubes with TiO2 nanostructures for the critical development of dye sensitized solar cells with future research directions are presented and discussed.
