Dye-sensitized solar cells have been under development for the last three decades but are yet to see the market. This has been attributed to stability issues of the electrolyte in the cell. Electrolytes can be liquid, quasi-solid, or solid. Liquid electrolytes were the first to be developed and, therefore, have been subject to radical revisions in both composition and applicability. They have shown the best power conversion efficiencies but have poor thermal stability. Although quasi-solid and solid-state electrolytes were developed to overcome these stability issues, they too have their limits. The aim of this paper is to explore the development of liquid electrolytes, outlining the current state of the technology and considering their potential in the photovoltaic market.

“…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).…”

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.

In this paper, Safranin-O as a viable photosensitizer in dye-sensitized solar cells (DSSCs) is introduced and its photosensitising properties respect to various concentrations and solvent is optimized. Moreover, the molecular structure of Safranin-O using density functional theory with the B3YLP method is computed in order to determine the Safranin-O energy bandgap in HOMO, LUMO and DOS. In the next level, the optimized Safranin-O dye is implemented as the photosensitizer within a DSSC and its functionalities investigated using the I-V curve as the figure of merit. In order to fully comprehend the absorption mechanisms within the solar cell structure, the full layer stack is simulated based on the finite element method (FEM) which shows that Safranin-O coated TiO 2 nanoparticles are capable of sustaining whispering gallery modes which further improves the optical absorption of the proposed structure.
