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.

Employing naturally extracted dyes and their derivatives as photosensitizers towards the construction of dye-sensitized solar cells (DSSCs) has been recently emerging for establishing sustainable energy conversion devices. In this present work, Rhodobacter Sphaeroides Photobacteria (Rh. Sphaeroides) was used as a natural source from which Bacteriopheophytine-a (Bhcl) dye was extracted. Further, two cationic derivatives of Bhcl, viz., Guanidino-bacteriopheophorbide-a (Gua-Bhcl) and (2-aminoethyl)triphenylphosphono-bacteriopheophorbide-a (2AETPPh-Bhcl) were synthesized. The thus obtained Bhcl, Gua-Bhcl and 2AETPPh-Bhcl were characterized using liquid chromatography–mass spectrometry (LC–MS) and their photophysical properties were investigated using excitation and emission studies. All three near-infrared (NIR) responsive dyes were employed as natural sensitizers towards the construction of DSSC devices, using platinum as a photocathode, dye-sensitized P25-TiO2 as a photoanode and I−/I3− as an electrolyte. DSSCs fabricated using all three dyes have shown reasonably good photovoltaic performance, among which 2AETPPh-Bhcl dye has shown a relatively higher power conversion efficiency (η) of 0.38% with a short circuit photocurrent density (JSC) of 1.03 mA cm−2. This could be attributed to the dye’s natural optimal light absorption in the visible and NIR region and uniform dispersion through the electrostatic interaction of the cationic derivatives on the TiO2 photoanode. Furthermore, the atomic force microscopy studies and electrochemical investigations using cyclic voltammetry, electrochemical impedance spectroscopy and Bode’s plot also supported the enhancement in performance attained with 2AETPPh-Bhcl dye.

This work aimed to study the natural dye extracted from Indonesian wild plants (Rivina humilis L.) using different solvents. The natural dye was extracted using the maceration method. Three different solvents, namely, aquades, acetone, and ethanol 96%, were used to extract natural dye from Rivina humilis L fruit. The absorbance spectra of the extracted dye were recorded using Ultraviolet-Visible (UV-Vis) spectroscopy. The different spectra of betalain pigment revealed the dye extract's dependence on the solvent. The functional groups of the extracted dye were analyzed using Fourier transform infrared (FTIR) spectroscopy. The adherence of carbonyl and hydroxyl groups from FTIR spectra indicated that this dye could anchor to a semiconducting material, e.g., TiO 2, which was commonly used in dye-sensitized solar cells (DSSC). The electrochemical properties of the extracted pigments were studied through higher occupied molecular orbital (HOMO) and lower unoccupied molecular orbital (LUMO) energy levels. Based on the results, the best performance to construct DSSC was achieved by natural dye adsorption with aquades solvent.
