“…The performance of DSSCs is significantly influenced by the role played by dye sensitizers (Ganta et al, 2019). Different varieties of dyes, including both organic and inorganic types, were employed in DSSCs (Rekha et al, 2019;Sharma et al, 2018). Currently, inorganic dyes such as Ruthenium are acknowledged as the most significant dyes for manufacturing DSSCs due to their remarkable efficiency (Jalali et al, 2020).…”

“…Currently, inorganic dyes such as Ruthenium are acknowledged as the most significant dyes for manufacturing DSSCs due to their remarkable efficiency (Jalali et al, 2020). However, these types of dyes tend to be costly, possess toxic properties, and present challenges in terms of their purification (Rekha et al, 2019). Recently, there has been extensive research into natural dyes because of their significant absorption in the visible spectrum, widespread availability in nature, straightforward sample preparation, cost-effectiveness, and eco-friendliness (Jalali et al, 2020).…”

Dyes are significant components in Dye Sensitized Solar Cell (DSSC) performance because they act as photosensitizers. Natural dye-based DSSC system fabrication innovations continue to be produced in an effort to improve DSSC performance efficiency. In this study, a DSSC system was developed using double components of natural dyes as natural photosensitizers to enhance DSSC efficiency. This method of making natural dye-based DSSC uses a combination of dye extracts from two different dye sources that have the potential as natural photosensitizers in DSSC. The research aims to investigate the impact of the combined use of two natural dyes and pH variations on DSSC performance. DSSC performance measurements encompass the short-circuit current (Isc), open-circuit voltage (Voc), and DSSC efficiency parameters. The obtained results indicate efficiency values for dyes (a) sappan wood/ethanol and turmeric/methanol; (b) turmeric/methanol and beetroot/ethanol; and (c) beetroot/ethanol and turmeric/distilled water. At neutral pH, the efficiency values are 2.09%, 2.10%, and 2.19%, respectively. Meanwhile, at acidic pH of 2.59%; 2.39%; and 2.71%. Notably, the dye efficiency values at acidic pH surpass those found at neutral pH conditions. The highest efficiency is observed in the combination of dye (c) beetroot/ethanol and turmeric/distilled water with efficiency reaching 2.71% at acidic pH.

“…It was determined that the most important dyes for the production of DSSC were inorganic dyes such as ruthenium-based (Ru-based) dyes. On the other hand, because of the composition of their make-up, they are hazardous to human health, extremely costly (because ruthenium is a rare metal), and challenging to purify [2]. Because of this, organic dyes have garnered a lot of attention due to their high absorption in the visible region, their ease of sample preparation, their low production costs, and their friendliness to the environment (they contain no contaminants and do not require additional refining or purification) [3].…”

In this study, natural dye sensitisers derived from ketum (Mitragyna speciosa-MS), spinach (Spinacia oleracea-SO), curry (Murraya koenigii-MK), papaya (Carica papaya-CP), and henna (Lawsonia inermis-LI) were investigated for dye-sensitised solar cells (DSSCs). Ultraviolet-Visible Spectroscopy (UV-Vis), Fourier Transform Infrared spectroscopy (FTIR), Open-Circuit Voltage Decay (OCVD) and Current to Voltage (I-V) were used to analyse the natural dye and the fabricated DSSC. It was observed that all dye solutions contain the majority of important functional groups of chlorophyll-based sensitisers, which is crucial for the dye-to-TiO2 (Titanium (II) Oxide) attachment, making them suitable sources of energy harvesting pigments. In this regard, the dye pH and chemical bonding of the respective dyes play a significant role that contribute to the overall performance of the DSSCs. It was discovered that a dye based on MK provided the best DSSC performance. This is because MK-based dye has higher content of functional groups, an optimal pH, and the slowest properties of back electron recombination among the OCVD measurements. Because of the combination of these properties, the open-circuit voltage (VOC), short-circuit current density (JSC), and power conversion efficiency (PCE) values have been determined to be 0.58 V, 2.48 mA/cm2, and 0.47%, respectively.
