Dye-Sensitized Solar Cell Synthesis Using Green Extract: Natural Approach

A sensitizer is a key component of an efficient solar design during the dye sensitization process. In the natural resources such as chlorophyll, a simple molecule of green dye can play an important role in the synthesis of solar cells. This report presented various natural dyes, which are very efficient for preparation of environment friendly solar cells. In green leaf, chlorophyll is present in wast majority and responsible for the harvesting large amount of visible light. Several modules such as leaves, fruits, flower petals, barks and stems used together for the preparation of sensitizers. Among the four natural dyes, a max efficiency of 0.13 % have been found for radish leaves during the synthesis of dye sensitized solar cells.
