“…In another instance, lemon and spinach were oven-dried at 60 • C for 24 h; 2 g of dried leaves of each were immersed in 20 mL of ethanol at room temperature and no light for a day, and lastly, filtered. Finally, in paper [44], where the basis for the dye of this study an efficiency of 0.115% was reported. For preparation of the dye, it was washed several times with distilled water to remove dust and other impurities.…”

Human beings are attempting to take advantage of renewable natural resources by using solar cells. These devices take the sun’s radiation and convert it into electrical energy. The issue with traditional silicon-based solar cells is their manufacturing costs and environmental problems. For this reason, alternatives have been developed within the solar cell field. One of these alternatives is the dye-sensitized solar cell (DSSC), also known as Grätzel solar cells. DSSCs are a type of solar cell that mimics photosynthesis. They have a photoanode, which is formed by a semiconductor film sensitized with a dye. Some of their advantages include low-cost manufacturing, eco-friendly materials use, and suitability for most environments. This review discusses four important aspects, with two related to the dye, which can be natural or synthetic. Herein, only natural dyes and their extraction methods were selected. On the other hand, this paper discusses the nanostructures used for DSSCs, the TiO2 nanostructure being the most reported; it recently reached an efficiency level of 10.3%. Finally, a review on the novelties in DSSCs technology is presented, where it is observed that the use of Catrin protein (cow brain) shows 1.45% of efficiency, which is significantly lower if compared to Ag nanoparticles doped with graphene that report 9.9% efficiency.

The rapid growth of the population severely influences the supply of energy, accordingly ensuring clean energy has become a big challenge now and will be in the future. Fossil fuels have been satisfying the energy demand until now, but fossil fuels, being non‐renewable sources, will not be able to satisfy the energy demand in the future and will have a negative impact on the environment. Renewable energy sources have become the most demanding topic for researchers in this crisis. The solar cell, which is an abundant renewable energy resource, converts solar power into electrical energy without any environmental damage. Silicon solar cells have higher efficiency, but their high manufacturing cost, complicated procedures and environmental issues restrict their usage. Then dye‐sensitized solar cells (DSSCs) have been introduced as an alternative to silicon solar cells. In DSSC, both natural and synthetic dyes are used. Though synthetic dyes provide higher efficiency, they are environmentally harmful. Afterward, the concept of natural dye‐sensitized solar cells (NDSSC) have been materialized where only natural dyes are used. Researchers and environmentalists are looking for natural dyes as a replacement for synthetic dyes in recent times, as natural dyes are plentiful, can be collected naturally and have no environmental effects. Natural dyes in the form of anthocyanins, carotenoids, flavonoids, chlorophylls, tannins and betalains are extracted from various portions of plants that include leaves, roots, flowers, fruits, seeds, barks, etc. In this review, we investigate natural sources of dyes, natural sensitizers (dyes), shortcomings and remedies, improvements in efficiency and stability, developments, and commercialization. In addition, recent advances and the comparison of natural and synthetic dyes have been discussed in this review.

“…The enhanced performance of the DSSCs was attributed to the incorporation of the nanocomposite layer using GO and also it was found that Hibiscus rosa-sinensis showed remarkable efficiency in the DSSC as a Darkwa et al, 2021). Natural dye extract from pomegranate and N719 dye based DSSC were fabricated for a comparative studies using UV-Visible spectroscopy, photovoltaic characterization and impedance spectroscopy to optimize various components for developing cost effective commercially available natural DSSC (Faraz et al, 2021). To enhance the photosenistizer efficiency and stability of the anthocyanin dye obtained form rose petal, it was co-sensitized with Astaxanthins extracted from Haematococcus Pluvialis, which encircles the anthocyanin and scavenges the free radical produced due to photocatalytic activity (PCA) and reduces the photodegradation (Prabavathy, et al, 2021).…”

Synthetic metalo-organic dye sensitized solar dyes show better efficiency but difficult to prepare in pure form and are not cost effective. Natural dyes based solar cells are more easily fabricated. Natural dyes or pigments can be obtained from fruits, seeds, leaves, roots, and flower. This review gives an insight into different types of natural dye photosensitizer containing Anthocyanins, Chlorophyll, Flavonoid, Xanthins and Carotenoids which can be co-sensitized to give better efficient Dye Sensitised Solar cell and has broad scope for research.
