Electrophoretic deposition is a straightforward, environmentally friendly, and cost-effective technique for depositing and synthesizing nanomaterials, particularly nanofilms of semiconductors. Key parameters in electrophoresis include deposition time and voltage. Zinc oxide, a semiconductor of significant interest in solar energy research, possesses favorable characteristics, notably, a band gap value of approximately 3.33 eV. In the realm of dye-sensitized solar cells, which represent the third generation of solar cells, zinc oxide has emerged as a compelling choice for a photoanode. This study focused on depositing thin films of zinc oxide through electrophoresis and applying them as photoanodes in dye solar cells. The results demonstrated that the electrodeposited films exhibited good reflectance in the visible spectrum (~60–90%), a band gap energy of 3.28 eV, and an incident photon conversion efficiency of approximately 4.48% for the electrodeposited film at 80 V for 5 min.

The optimization of the combination of the optical properties of transparent ITO nanoparticles with the optical and morphological properties of TiO2 as well as the absorbing properties of chlorophyll dyes plays a very important role in the performance of DSSC solar cells. Therefore, it is necessary to characterize these properties to produce maximum DSSC solar performance. The stages of research are fabrication, characterization, and performance test. TiO2 film was made by coating TiO2 on ITO and soaking in chlorophyll dye. Alloy DSSC solar cells are characterized by optical, electrical and morphological properties. Characterization of optical properties, reflectance, absorption of chlorophyll dye using UV-Vis spectrometer. Electrical properties were characterized by measuring the current-voltage in the coating, DSSC solar cell performance and grain size morphology with XRD. Performance optimization of DSSC solar cells was obtained at the grain size of the transparent nanoparticle layer 54.87 at annealing temperature of 50℃ and chlorophyll absorption power of 20.900 mg/l efficiency of 0.038%. The grain size is 48.71, annealing temperature is 60℃ and chlorophyll absorption is 73.20 mg/l, the efficiency is 0.005%. The grain size is 44.46 the annealing temperature is 50℃ and the chlorophyll absorption is 34.6 mg/l and the efficiency is 0.020%. The conclusion is that the grain size of transparent nanoparticles, annealing temperature and chlorophyll absorption affect the efficiency of DSSC solar cells.

Currently, the situation of the economy is drastically affecting the growth and development of some growing nations with regard to the energy sector. Most developing countries still depend majorly on fossil fuels. Considering the environmental nuisance arising from the dangerous emissions from the combustion of fossil fuels and climate concerns, there is urgent need to seek other alternative energy sources to meet up with the global energy consumption demands as the human population is steadily on the increase. Energy from the sun is one of the most alternative sources that can be assessed freely as well as help in mitigating global climate change. Recent advances on dye sensitized solar cells (DSSC) using natural dyes is a welcome advancement for replacing high cost ruthenium dye. The application of natural dye for DSSC is due to their abundance in nature, low cost, simple and safe extraction from various natural resources without requiring complex synthetic procedures. Dye enhances the performance of a DSSC by providing the source of photo excited electrons. Recently, there has been research on areas that supports the exploration of different photoactive natural dyes. In this paper, we reviewed some natural dyes, energy conversion efficiencies of NDSSCs, methods of dye extraction, characterization and various fabrication techniques for improved DSSC performance from various researched articles. It was observed that there were variations in the recorded DSSCs performances and this can be attributed to steps employed by the researchers in the methods of dye extraction and DSSC fabrication.
