“…However, the dyes based on ruthenium compounds are relatively expensive, and their availability is limited. Alternatives to these dyes, such as organic dyes having similar properties, are being researched [15][16][17][18][19][20][21]. Natural pigments are widely used as photosensitizers in DSSCs to study photoelectrochemical properties with TiO 2 as well as ZnO photoelectrodes.…”

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.

“…The efficiency and stability of these cells can be affected by various factors like light absorption by the dye, porosity of the TiO2 film, surface area of the nano-particles, electron transport and so on. Controlling these parameters can be obtained by various ways such as using different dyes [3][4][5][6][7][8][9][10][11][12][13][14][15], semiconductors with different band gaps or morphology [16] or electrolytes [17][18][19]. Although the performance of natural dyes yields lower efficiency than synthetic dyes, its benefits as low cost, ease of manufacturing, environmentally safeness, and abundance, encouraged researchers to focus on the improvement of its efficiency.…”

In this work, three extracts of plant leaves were used as sensitizers for dye-sensitized solar cells (DSSCs). These plants are Safflower, Medicago sativa and Ros marinus oficinalis. The natural dyes were extracted before and after grinding the plant leaves. The UV-VIS absorption spectra of the three extracts in ethyl alcohol solution were measured. The DSSCs were assembled using TiO2 films on Fluorine-doped tin oxide (FTO) coated glass. The DSSCs sensitized with the extracts of grinded leaves showed a better performance compared to those sensitized with un-grinded leaves with the highest efficiency of 0.115 % was obtained for the DSSC sensitized with Medicago sativa. The performance of the DSSCs sensitized with Safflower and Ros marinus oficinalis was significantly improved by acid treatment of the FTO substrates. Impedance spectroscopy of the fabricated cells was also carried out.

“…One of the interesting developments of solar cell technology is dye-sensitized solar cell (DSSC) invented by Brian O'Regan and Michael Grӓtzel in 1991 [1]. DSSCs and organic cells are considered the third generation of photovoltaic cells [2][3][4][5]. DSSCs are promising and have many advantages over silicon solar cells such as low cost and green energy photovoltaic devices.…”

In this paper, we used the extracts of three fresh plant seeds as photosensitizers for DSSCs based on TiO 2 nanopowder as a semiconducting material. Ethanol was used to extract the dyes from the seeds. The fill factors of the cells sensitized with the seeds of Raphanus raphanistrum, Lepidium sativum and Dianthus barbatus were 0.45, 0.40, and 0.48, respectively, whereas the efficiencies were 0.05, 0.03, and 0.15. The performance of the DSSC sensitized with Dianthus barbatus was investigated at various pH values of the dye solution and found to have a considerable effect of the cell efficiency.
