A Brief Review on Natural Photosensitizer Based Dye-Sensitized Solar Cells For Photoelectric Conversion

Abstract

The main purpose of this brief review article is to provide the simple and short knowledge of dye sensitized solar cell technology from the working principles to the commercial application. This paper explains the role of the sensitizer, construction of Dye sensitized solar cell (DSCC) and preparation of electrodes. In DSCC, dye is used instead of metal. Natural dyes are extracted by various parts of plant like fruits, seeds, flower and leaves. Green Parts of plant contain chlorophyll and coloured parts like flower, buds, etc. contain anthocyanin. Both chlorophyll and anthocyanin absorb electromagnetic radiation. Selection of efficient dye plays a key role in enhancement of efficiency of the cell.
