Natural dye (chlorophyll, anthocyanin, carotenoid, flavonoid) photosensitizer for dye-sensitized solar cell: A review

Abstract

For many years, dye-sensitized sunlight cells (DSSC), which are feasible and have significant potential to harvest and convert light into renewable energy, have been the subject of serious research. DSSC is a great alternative for low-cost solar panels due to its simplicity in fabrication and acceptable efficiency. While synthetic dyes can produce higher efficiency, their production costs and complexity in synthesizing toxic chemicals that are harmful to the environment, people, and the environment present another problem. Therefore, several studies have focused on natural dyes extracted from plants (chlorophyll-anthocyanin, flavonoid and carotenoid) because of their advantages such as high absorption, low cost, no toxicity, eco-friendly and easy extraction. This review also highlights the development of dye-sensitized sun cells by using natural dyes as photosensitizers.

Investigating the effect of solvent on the efficiency of natural pigment- based dye-sensitized solar cells

“…Investigating the impact of solvent on natural pigment-based dye-sensitized solar cells yields wide-ranging implications. It promises a transformative influence on renewable energy generation, driving the advancement of solar energy harvesting technologies (Mejica et al, 2022b). Optimizing solvent selection enhances the efficiency of these cells, potentially revolutionizing their design to employ eco-friendly natural pigments for direct electricity generation from sunlight.…”
