“…Several interesting tracks including natural dyes were explored: the molecules of the group tannins, anthocyanins, carotenoids or chalone and many other compounds sometimes extracted from plant seeds answered as celery or onion. Natural dyes are a less expensive alternative, faster, environmentally friendly and low energy consumption for photosensitive pigment cell (DSSC) compared to the ruthenium complex [17,21,32].…”

Many dyes are contained in plants and are used for coloring a medium. They are characterized by their content of dyes molecules. They stimulate interest because they are part of a sustainable development approach. There are several chemicals families of plant dye which are contained in more than 450 plants known around the world. In this article, a study based on literature allowed us to realize an inventory of the main dyes plants potentially present in Morocco. A list of 117 plants was established specifying their botanical families, chemical Composition, Colors and parts of the plant used.

“…Carotenoids, chlorophyll, cyanidin, and delphinidin as well as cyanine and nasunin have been studied extensively. Although natural pigments are promising sensitizers in DSSCs, the efficiencies obtained with these pigments are considerably lower than those obtained with synthetic dyes [22][23][24][25][26][27][28].…”

A dye-sensitized solar cell (DSSC) was assembled using a dye 4-(3-chloro-1, 4-dioxo-1, 4-dihydronaphthalen-2-ylamino) benzoic acid with ZnO as a photoanode. It was synthesized using 2, 3-dichloro 1, 4-naphthoquinone and p-amino benzoic acid. The spectral features of the dye were analyzed in ethanol using experimental and computational methods. The theoretical investigations revealed that the synthesized dye may act as a sensitizer in DSSCs. The photoelectrochemical performance was tested under direct sunlight using a sandwich type DSSC. The photovoltaic data of the dye adsorbed on ZnO films indicated thepower conversion efficiency of 1.07 % under sunlight with a light intensity of 39 mW·cm-2.

“…In spite of these achievements cost and eco-friendly nature of these cells could be improved if the natural products were involved in construction of these cells. Cost effective ecofriendly dyes and electrolyte have been utilized in these solar cells and were successful in achieving better conversion efficiencies [8][9][10][11][12][13]. This paper presents a green approach to fabricate dye sensitized solar cells via biosynthesis of photoelectrode material.…”

Rice shaped ZnO nanoparticles have been synthesized for the first time by a biological process using Amorphophallus konjac tuber extract and used as a photoanode in a dye sensitized solar cell. The glucomannan present in aqueous tuber extract acted as a reducing agent in the synthesis process, further it also acted as a template which modified and controlled the shape of the nanoparticles. The synthesized nanoparticles were dried by microwave irradiation followed by annealing at 400°C. The FESEM and TEM images confirmed that the synthesized ZnO nanoparticles had rice shaped morphology. Furthermore, the X-ray diffraction studies revealed that the prepared ZnO nanoparticles exhibited wurtzite phase with average particle size of 17.9 nm. The UV-Vis spectroscopy studies confirmed the value of band gap energy of biosynthesized ZnO nanoparticles as 3.11 eV. The photoelectrodes for dye sensitized solar cells were prepared with the biosynthesized ZnO nanoparticles using doctor blade method. The photoelectrode was sensitized using the fruit extract of Terminalia catappa, flower extracts of Callistemon citrinus and leaf extracts of Euphorbia pulcherrima. The dye sensitized solar cells were fabricated using the sensitized photoelectrode and their open circuit voltages and short circuit current densities were found to be in the range of 0.45 V to 0.55 V and 5.6 mA/cm 2 to 6.8 mA/cm 2 , respectively. Thus, the photovoltaic performances of all the natural dye sensitized ZnO solar cells show better conversion efficiencies due to the morphology and preparation technique.
