“…The peak shift indicates that there has been a reaction to the formation of the Fe 3+ -chlorophyll complex. It is estimated that an electronic transition factor influences the shift in wavelength in Metal-to-Ligand Charge Transfer (MLCT), the transition of electrons from metals to ligands [20]. The d-d transition can influence the MLCT phenomenon and the maximum wavelength in the visible light area.…”

The bandgap energy (Egap) of TiO2 material modified with metal-chlorophyll complex compounds (M = Cu2+, Fe3+) was observed. Chlorophyll (Chl) was isolated from cassava leaves, and its UV-Vis spectra showed absorption peaks in the Soret band region (410 nm) and in the Q band region (665 nm), which is the typical peak of chlorophyll. Copper(II)-chlorophyll complex was prepared from the reaction between chlorophyll and CuSO4.5H2O, while the iron(III)-chlorophyll was synthesized from chlorophyll and FeCl3.6H2O in methanol solvent under reflux at 65°C. The presence of copperand iron metals in the chlorophyll metal complexes was identified using Atomic Absorption Spectroscopy in methanol solution. The absorption of copper measured in Cu2+-Chl was 0.0488 (0.4805 mg/L), while the iron atom in Fe3+-Chl was 0.0050 (0.0195 mg/L). The UV-vis spectra demonstrate the hypsochromic shift of the Soret band to 405 nm (Cu2+-Chl) and 402 nm (Fe3+-Chl). The Infrared spectra of chlorophyll after being complexed with copper(II) shows the increase of vibrational absorption wavenumber of the C=N group from 1225.06 cm-1 to 1241.94 cm-1 indicates the coordination of the metal ion on the N atom in the pyrrole ring. The shift in the absorption band on the Fe3+-Chl spectrum was seen for the C=O ester group from 1720.49 cm-1 to 1721.10 cm-1 indicating the metal ion bonding in the C=O group of esters. The DR-UVis analysis of TiO2/metal-chlorophyll shows a bathochromic shift towards the visible light region. By using the Tauc plot method, it was observed that the Egap of TiO2 reduces from 3.08 eV to 2.89 eV and 2.93 eV in the compound of TiO2/Cu2+-Chl and TiO2/Fe3+-Chl, respectively.

“…Dye-sensitized solar cell (DSSC) is evolving as one of the most promising photovoltaic technologies due to their low cost, environmentally friendly, and simple fabrication compared to typical silicon-based solar cells [1]. The performance of cells depends on the quality of materials used as semiconductor electrodes and photosensitizers or dyes [2]. Natural dyes are organic and in plant organisms along with leaves, flowers, fruit, and vegetable.…”

Performance of dye-sensitized solar cells extracted dye from wood apple leaves

In this work, wood apple leaves dye has been extracted, characterized, and examined as a potential photosensitizer for dye-sensitized solar cells (DSSCs). The dye was extracted in an ethanolic medium from the fresh wood apple leaves and characterized using thin-layer chromatography (TLC), ultraviolet-visible (UV-Vis), and Fourier transform infrared (FTIR) spectroscopy. The current density-voltage (J-V) characteristics measurements were performed on the two assembled DSSCs for 1- 22 days using fresh and seven days old extracted dye. The characterization results revealed that the extracted dye mainly contains the compound of carotenoids (neoxanthin), chlorophyll-a, chlorophyll-b, and their derivative (pheophytin) with various functional groups. The J-V characteristics of DSSCs indicate that an open-circuit voltage and short circuit current density radically decrease with increasing time, thus degrading the efficiency of cells. A degraded DSSCs suffered from high defect recombination may be induced by Mg ions migrating from chlorophyll dye into DSSC. Therefore, the extracted dye may be used for energy harvesting from the wood apple leaves.

“…Semakin banyak molekul dye yang diubah untuk diadsorpsi maka penyerapan foton akan menjadi lebih besar dan menghasilkan nilai efisiensi yang lebih tinggi. Jumlah molekul dye yang diadsorpsi pada lapisan TiO2 dipengaruhi oleh molaritas larutan dye yang diserap ketika lapisan TiO2 dicelupkan dalam larutan dye [24] .…”

<p>Dye sensitized solar cell (DSSC) is the third generation of solar cells that currently developing by researchers to get the best performance. The selection of dye as a component of DSSC has a big influence in the light absorption process. In this study, DN-F01 organic dye was used as a sensitizer with various concentrations. The optical properties test was carried out on the DN-F01 dye solution by UV-Vis spectrophotometer (Shimadzu UV-1800) and the DSSC fabricated performance was tested by portable solar simulator (ORIEL Sol1A). From the results, the DN-F01 absorbance has ability to absorb light in the 300-500 nm wavelength range. The greatest efficiency value in this research is 2.44% obtained from the sample was immersed with the largest concentration of dye DN-F01 which has the smallest band gap energy of 2.38 eV.</p>
