“…Nishantha et al [189] studied the Kopsia flavida fruit, found the anthocyanin dye used in DSSC and reported the performance of DSSC that included I sc = 1.2 mAcm À 2 , V oc = 0.520 V and FF = 0.620. Danladi et al [95] manufactured DSSC applying anthocyanin dye extracted from the roselle flower and reported performance including I sc = 0.0259 mAcm À 2 , V oc = 0.432 V, FF = 0.594 and η = 0.0067 %. Alhamed et al [98] studied on raspberries, hibiscus, chlorophyll anthocyanin dyes and reported the performance of DSSC with I sc = 0.6 mAcm À 2 and V oc = 0.42 V, FF = 0.60, η = 3.04 %.…”

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.

This work studies the interaction between natural dyes obtained from Peruvian Zea mays and Bixa orellana seeds and nanostructured titanium dioxide in order to evaluate their function as sensitizers into solar cell devices. The effective attachment of dyes to the TiO2 layer is corroborated by the comparison of UV-Visible absorption and FT-IR spectra of the extracted dye solutions and sensitized TiO2 electrodes. The principal compounds from the seed extraction of Zea mays and Bixa orellana are cyanidin-3-glucoside (C3G) and bixin, respectively, which were analyzed in an isolated dye/cluster TiO2 system by molecular dynamic simulation. The results showed that the chemisorption is carried out through a consecutive deprotonation process and Ti-O bond formation by the monodentate OH and COOH anchoring groups, for C3G and bixin, respectively. Finally, we tested the effect of the dye – TiO2 interaction on the charge transfer by the comparison of the current-voltage (I-V) curves and incident photon-to-current conversion efficiency (IPCE) of the cells. We found that dye agglomeration in films with Bixa orellana and the high charge recombination of films with Zea mays are critical points to be solved. For this reason, we propose the pretreatment of the TiO2 film before sensitization with Bixa orellana and analyze the effects of pH in Zea Mays solution, in order to obtain better device efficiencies.

Abstract:The enhancement in efficiency of dye sensitized solar cells decorated with size-controlled silver nanoparticles based on anthocyanins as light harvesting pigment through successive ionic layer adsorption and reaction (SILAR) was demonstrated. Studies indicate that, the short-circuit current density (J SC ) and open-circuit voltage (V OC ), of DSSCs containing AgNPs were significantly improved. The photovoltaic (PV) performance decreased with increasing size of AgNPs from one SILAR cycle to two SILAR cycles, the best performance was achieved using the anode prepared with one SILAR cycle. An enhancement of 35.8 % was achieved when the thickness was around 16 nm (one SILAR) over the bare FTO device. When the size of AgNPs was around 32 nm (two SILAR), an enhancement of 10.4% was recorded over the reference device. This selective enhancement in efficiency in the Ag plasmonic absorption regions is indicative of the fact that the incorporation of metal nanoparticles is beneficial for enhanced absorption and charge separation.
