“…The best performance was obtained from the DSSC sensitized by the spinach oleracea extract after drying where the efficiency of the cell reached 0.29%. These results are similar to those of the DSSCs sensitized by other natural dyes in previous works [16,17]. It is clear from Table 1 that some dyes exhibit higher conversion efficiency after drying whereas others have better performance before drying.…”

Different natural dye extracts have been prepared and used as sensitizers in the fabrication of dye-sensitized solar cells (DSSCs). These dyes have been extracted from both fresh and dried raw materials. The absorption spectra of these dyes have been investigated by UV-VIS spectrophotometry. DSSCs were assembled using TiO2 and ZnO nanostructured, mesoporous films. Photovoltaic parameters such as short circuit current density Jsc, open circuit voltage Voc, fill factor FF, and overall conversion efficiency η for the fabricated cells were determined under 100 mW/cm2 illumination. The immersion time of the nanocrystalline-TiO2 electrode in spinach extract and the temperature at which this process occurs were optimized. The optimal dying temperature is found to be 60 °C and the efficiency of the DSSC is found to saturate to 0.29% after 12 hr of soaking in the dye solution.

“…The performance of natural dye sensitizer in DSSC has been estimated using fill factor (FF), energy conversion efficiency (η) (J sc ), open circuit voltage (V oc ), and short circuit current. Many parts of a plant have been tested by Researchers (see Table 1) and various useful dyes have been highlighted as photo-sensitizers for DSSC from natural products [35][36][37][38][39][40][41][42]. …”

Abstract-In a conversion system of pure and non-convectional solar energy to electricity, dye sensitized solar cells (DSSCs) encourage the fabrication of photovoltaic devices providing high conversion efficiency at low cost. The dye as a sensitizer plays a vital role in performance evaluation of DSSCs. Natural dyes (organic dyes) has come to be a worth-while substitute to the rare and expensive inorganic sensitizers because of its cost effective, extreme availability and biodegradable. Different parts of a plant like fruits, leaves, flowers petals and bark have been tested over the years as sensitizers. The properties, together with some other parameters of these pigments give rise to improve in the operation standard of DSSCs. This review hash-out the history of DSSC with a focus on the recent developments of the natural dyes applications in this specific area with their overall appearance, the various components and the working principle of DSSCs as well as the work done over the years on natural dye based DSSCs.

“…It has higher electron mobility than TiO 2 and lower recombination probability. ZnO based solar cells can be fabricated at low cost using environmentally friendly materials: ZnO and natural dye extraction from locally available fruits and flowers (Chang & Lo, 2010;Bhogaita et al, 2016;Gomez-Ortiz et al, 2010). However, ZnO based DSSCs with natural dyes show lower efficiency, intensive studies have been conducted to lower the cost of DSSCs to maintain the same efficiency of silicon-based solar cells.…”

Preparation and Characterization of Zinc Oxide Based Photoanode for Dye-sensitized Solar Cell using Delonix Regia Natural Dye Extract

et al. 2017

As of late, research on the fabrication of natural dye-sensitized solar cells has been growing tremendously, largely due to its low cost and environmentally friendly nature. We have fabricated Zinc Oxide (ZnO) based Dye-sensitized Solar Cell (DSSC) using Delonix Regia, locally known as the Gulmohar flower natural dye extract. Zinc Oxide nanostructure films were allowed to grow on Fluorine-doped Tin Oxide (FTO) substrates via hydrothermal process. The seed layer for this was prepared by the spin coating method. The ZnO film's structure, topology, and optical properties were then studied using X-ray Diffraction (XRD), an Atomic Force Microscope (AFM) and an Ultraviolet Visible (UV-Vis) Spectrophotometer respectively. The X-ray results showed the hexagonal system structure of ZnO oriented along (101) planes. The effect of ethylene glycol on the structural property of ZnO film was also studied. The current voltage curve of DSSC showed the open circuit voltage and short circuit current of 360 mV and 80 µA respectively.
