“…From this Nyquist plot, we can determine that adding TBL significantly changed the impedance of photoanodes, but not R1, which shows the addition of TBL does not affect the electron transfer resistance of the counter electrode. From Table 1, it can be found that adding TBL effectively reduces R2, which can be attributed to the reduction of the electrolyte contact with the FTO substrate by TBL [27]. A recombination reaction occurs when the oxidized electrolyte comes into contact with electrons that diffuse from the conduction band of the active layer TiO2 to the FTO substrate.…”

In this study, the titanium dioxide (TiO2) thin film prepared by radio frequency magnetron sputtering system (R.F. sputtering) was used as the blocking layer (BL) of dye-sensitized solar cells. TiO2 blocking layer (TBL) is used to reduce the recombination reaction caused by contacting the oxidized electrolyte with the fluorine-doped tin oxide (FTO) substrate through the active layer with porous structure. We analyzed the effect of TBL introduction on the electrochemical impedance between photoanodes by potentiostat and calculated the electron lifetime, which proved that TBL can effectively improve the process of electron transfer. In addition, the direct impact of TBL on the photovoltaic performance of DSSC was determined through the quantum efficiency (QE) measurement system and current density-voltage (J-V) measurement system, and it was found that the short-circuit current density (JSC), external quantum efficiency (EQE), fill factor (FF) and photoelectric conversion efficiency (PCE) were all improved. DSSCs with TBL also exhibited better performance under low illumination due to the reduced recombination reaction.

During the last four centuries, there have been extensive research activities looking for green and clean sources of energy instead of traditional (fossil) energy in order to reduce the accumulation of gases and environmental pollution. Natural dye-sensitized solar cells (DSSCs) are one of the most promising types of photovoltaic cells for generating clean energy at a low cost. In this study, DSSCs were collected and experimentally tested using four different dyes extracted from Mentha leaves, Helianthus annuus leaves, Fragaria, and a mixture of the above extracts in equal proportions as natural stimuli for Tio2 films. The result show that solar energy was successfully turned into electricity. Additionally, DSSCs based on mixtures of dyes showed better results than those based on single dyes. Efficiency (η) was 0.714%, and the fill factor (FF) was 83.3% for the cell area.

“…Dye represents the core component of DSSC and has the function of receiving photons and also anode sensitization 7 . Zatirostami 11 in his journal used N719 dye to improve its photovoltaic performance and applied a blocking layer at the interface TiO 2 /ZnO for reduce recombination problems. In his research, he found an increase in DSSC efficiency by 7.1%.…”

The energy demand for supporting the activity of human life is increasing where fossil fuels decreasing sharply every year and have an impact on increasing CO 2 emissions in the environment. An alternative solution for providing practical energy needs is using renewable energy such as solar cells. For environmentally friendly, economical, and efficient concepts, dye-sensitized solar cell (DSSC) is a promising alternative for the photovoltaic field. The performance of a DSSC depends on many factors, such as electron collection at the photoanode, photoanode light-harvesting efficiency, and others. In this review article, we observe the influence of synthetic and natural dye materials on light-harvesting efficiency at photoanodes. The chemical structure of dyes plays an essential role in increasing photon absorption, thereby increasing electron injection and conversion efficiency. In addition to dyes, we also reviewed the influence of the shape of the DSSC structure, namely the sandwich, monolithic, and honeycomb structures, on the performance of DSSCs.This approach helps develop a narrative about the potential and relationship of dyes and structure in increasing efficiency as a guide for synthesizing new materials in the future.
