Plant Seeds-Based Dye-Sensitized Solar Cells

Abstract

<p align="justify"> <span style="font-family:Verdana;">In this work, we investigate the performance of dye-sensitized solar cells (DSSCs) based on natural dyes extracted from ten different plant seeds. The extracts were characterized by UV</span><span style="font-family:Verdana;">-</span><span style="font-family:Verdana;">VIS absorption spectra. The solar cells were assem</span><span><span style="font-family:Verdana;">bled using a TiO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> mesoporous film on FTO-coated glass. The photovoltaic properties of the DSSCs were studied under an incident irradiation of 100</span></span><span> </span><span><span style="font-family:Verdana;">mW/cm</span>^{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">. The best performance was for the DSSC sensitized with </span><i><span style="font-family:Verdana;">Eruca sativa</span></i><span style="font-family:Verdana;"> with a solar energy conversion efficiency of 0.725%. Moreover, the validity of these extracts </span></span><span style="font-family:Verdana;">was</span><span><span style="font-family:Verdana;"> compared using two types of semiconductor layers (TiO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> and ZnO), and finally the photovoltaic properties of one of these dyes w</span></span><span style="font-family:Verdana;">ere</span><span style="font-family:Verdana;"> studied using different types of electrolytes.</span><span></span> </p> <p> <span></span> </p

Dye Sensitized Solar Cells Based on Hydrazonoyl Synthetic Dyes

“…Much attention has been paid to survey the effective sensitizer dyes [4]. Synthetic [5][6][7][8] and natural [9][10][11][12][13][14][15][16][17] dyes have been widely investigated as photosensitizers for DSSCs. TiO2 has been widely studied for efficient DSSCs.…”

Improvement of the Performance of Purple Carrot Sensitized Solar Cells by Acidic Treatment of FTO Glass Substrate and TiO2Film

“…This effect was clearly obvious in improving electrical conductivity leading to reduced recombination. Treating the DSSC sensitized with Glycyrrhiza glabra with HCl led to an efficiency enhancement of about 300% [17].…”

Dye-sensitized solar cells based on dyes extracted from dried plant leaves

“…Natural pigments extracted from fruits and vegetables, such as chlorophyll, have been extensively investigated as DSSC sensitizers [7][8][9][10][11][12][13].…”

“…Since the pioneering work of O'Regan and Grätzel in 1991 [1], great attention has been directed to dye-sensitized solar cells (DSSCs) as cheap, effective, and environmentally benign candidates for a new generation of solar power devices [2][3][4][5][6][7][8][9][10][11][12][13]. A DSSC is a photoelectrochemical device that effectively converts sunlight into electricity.…”
