“…Then, six types of counter electrodes have been prepared by using these different forms of carbon according to our previous study [20]. Here, the conductive side of one ITO coated glass was placed over the tip of a candle flame for 30 s to get a dark shade of carbon for one of the counter electrodes [19].…”

Efficiency of dye-sensitized solar cell (DSSC) depends on several interrelated factors such as type and concentration of dye, type and thickness of photoelectrode and counter electrode. Optimized combination of these factors leads to a more efficient cell. This paper presents the effect of these parameters on cell efficiency. TiO 2 nanoporous thin films of different thicknesses (5 µm to 25 µm) were fabricated on indium doped tin oxide (ITO) coated glass by doctor blading method and characterized by inverted microscope, stylus surface profiler and scanning electron microscope (SEM). Natural organic dye of different concentrations, extracted from turmeric, was prepared with ethanol solvent. Different combinations of dye concentrations and film thicknesses along with different types of carbon catalyst have been investigated by I-V characterization. The result shows that the cell made of a counter electrode catalyst material prepared by candle flame carbon combined with about 15 µm thick photoelectrode and 100 mg/mL dye in ethanol solvent, achieves the highest efficiency of 0.45 %, with open circuit voltage of 566 mV and short circuit current density of 1.02 mA/cm 2 .

“…Meanwhile, there are still few studies investigating the influence of the TiO2 layer thickness. Characterization is required to determine the ability of TiO2 to bind to the dye and then affects the power output produced [37,38]. Therefore, the objective of this research is to utilize red dragon fruit as a dye base for DSSC manufacture and to determine the effect of TiO2 thickness on DSSC performance by varying its thickness.…”

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.

“…DSSCs became more popular among other generations of solar cells in the photovoltaic research world when O'Regan and Gräetzel reported an efficiency (η) of 7.1% using inorganic Ruthenium (II) dye as a sensitizer for the fabrication of DSSCs [2]. This paves way for several investigations to be conducted using a different technique to improve the DSSC performance [3][4][5][6][7]. Compared to other categories of solar cell generations [1], DSSCs are low-cost, more eco-friendly photovoltaic devices.…”

Cost and energy payback time in relation to solar cell performances is one of the key parameters considered for mass application. In this research work, a low-cost, easily fabricated, and the more eco-friendly photovoltaic device was successfully developed using the dye synthesized from teak plant leaves. The dye-sensitized solar cell (DSSC) is made up of photoelectrode and counter electrodes. The photoelectrode was prepared by depositing zinc paste on an active area of 1cm2 of an Indium tin oxide (ITO) glass. The glass was annealed at a temperature of 4500C for 30 minutes and stained in a beaker containing teak dye (a dye extracted using ethanol) for 24 hours. Another ITO glass was placed some centimeters above a candle flame to form the counter electrode; the effect was a dark-shaded ITO glass. To have working DSSCs, a binder clip was introduced to couple the two electrodes and three drops of iodine (as an electrolyte) were dropped in between the electrodes to complete the fabrication process. The ethanol-extracted dye has an absorption spectrum of 342 nm at a small peak and a broad absorption wavelength in the range of 412-664 nm. The power conversion efficiency (ƞ) of 0.44% was achieved through the developed solar cell.
