Technologies are developing day by day. The main threat to the environment is the generation of greenhouse gases due to the combustion of fossil fuels . It affects the survival of living organisms. Renewable energy is essential for the society . The most demanding renewable source, solar energy is replaced instead of fossil fuel. Solar energy is the inexhaustible source of energy on earth . Dye sensitized solar cells (DSSC) is working based on the solar energy. The present research is to produce a highly efficient DSSC. In this review paper, we are dealing with natural dyes, various pigments in the dye and sort out the potential of various natural dyes from various research articles.
