“…Thus, the natural photosensitizer from the telang flower extract has the potential to produce high-efficiency DSSCs [40]. Furthermore, Ndeze et al reported the ability of the carbonyl and hydroxyl groups of anthocyanins to retain color on the surface of TiO 2 and facilitate HOMO to LUMO electron transfer of dyes which were then transferred to the TiO 2 conduction band [41].…”

The potential of dye-sensitized solar cells (DSSC) as an alternative to depleting fossil fuels has been investigated. To optimize performance and efficiency, the effectiveness of PVDF and PVDF nanofiber (NF) membrane-based electrolytes in suppressing solvent leakage and evaporation in liquid electrolyte systems was evaluated. SEM results for PVDF NF membranes showed the formation of a network with a three-dimensional structure with a diameter of 100–300 nm and an average thickness of 0.14 mm. The Infrared (IR) spectrum shows the electrolyte and polymer-PVDF interactions. Differential Scanning Calorimetry (DSC) curve shows the melting transition of PVDF NF 7.66% lower than PVDF. Efficiency and resistance of DSSC based on natural dyes as measured by multimeter and Electrochemical Impedance Spectroscopy (EIS) at a solar intensity of 100 mW/cm2 showed the highest efficiency of anthocyanin-based DSSC from telang (Clitoria ternatea L.) flower extract. Its use as a photosensitizer in an electrolyte system based on PVDF NF membranes resulted in an efficiency that was not significantly different from that of liquid electrolytes (1.69%).

“…Artificial photosynthesis aims to mimic photosynthesis processes, to convert photons into fuel. During photosynthesis chlorophyll-P680 absorbs photons causing electron photoexcitation, exited electrons transfer to pheophytin then the chloroplast electron transport chain, separating the oxidised chlorophyll-P680 and free electron [3] . Oxidised chlorophyll-P680s undergo the Kok Cycle and free electrons produce NADPH.…”

Dye Sensitized Photoelectrochemical Cells (DS-PEC) are a promising development for artificial photosynthesis. Currently however photoinduced conversion of water to hydrogen and oxygen remains limited by desorption, alternative processes and charge accumulation. This brief literature review will primarily focus on transition metal complex chromophore catalyst dyads, for water oxidation catalysis (WOC) as well as hydrogen evolution catalysis (HEC). Assessing the dyads individual charge separation, electron transfer and catalytic photoelectrochemical properties. Comparing and contrasting the techniques employed by Dye Sensitized Photoelectrochemical Cells (DS-PEC) dyads in addition to collectively evaluating their current limiting factors and suggesting potential developments for further work.

“…Many uses organic materials, organometallic compounds and inorganic substances. Despite the fact that their efficiencies have been low and the stability of the absorber material is often too short for commercial applications, there is a lot of research invested into these technologies as they promise to achieve the goal of producing low-cost, high-efficient solar cells [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][42][43][44][45][46].…”

“…O'regan and Gratzel [20] have conducted a simple fabrication solar cell research known at this time as dye sensitized solar cell in 1991. This solar cell has received great attention for its simple fabrication process, low production costs, relatively high conversion efficiency and, environmentally friendly [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. The largest energy conversion efficiency ever produced by this solar cell is about 11% [35,36].…”

A solar cell is an electrical device used to convert the energy of sunlight directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. One type of solar cells that uses plant dyes is the dye-sensitized solar cell (DSSC). The DSSC is in the form of a structural arrangement known as a sandwich structure, consisting of conductive glass as transparent electrode, titanium dioxide (TiO2) sensitized by plant dyes, electrolyte, and a metal electrode as a counter electrode. The paper aims to study the effect of TiO2 thickness on DSSC performance utilizing red dragon fruit flesh extract as a dye. Three variations in the thickness of the TiO2 layer evenly positioned in the conductive area are tested. The thicknesses of the TiO2 layer are 99 µm, 129 µm and 141 µm respectively. The DSSC performance is tested outdoors with sunny weather conditions from 9:30 am to 1:30 pm. A calibrated Arduino measurement kit is used to measure the voltage and current values produced by the DSSC prototype. Testing with a thickness of 141μm resulted in the highest maximum power value of 532.26 mW among the three thickness variations.
