Increasing the efficiency of solar cells with natural dyes

What is it about?

In this study, luminous solar concentrates made of natural dyes were utilized to increase the solar cells’ efficiency. Since it has no effect on the dyes’ qualities, natural dyes (black lemon, pomegranate, and betalains) were utilized in this investigation after being dissolved in pure water as a solvent (0.001, 0.002, 0.003) grams per 100 ml of pure water. Zinc oxide nanoparticles were added after the dyes were dissolved in water to create the concentrations needed for the study, and the absorbance and fluorescence were then computed for each concentration. The study of the optical characteristics was conducted between 200 and 800 nm in wavelength. The findings demonstrated that raising the dye concentration causes the absorbance to increase in intensity and decrease in the Fluorescence. However, as the concentration of the dyes increases, the absorbance increases and the fluorescence falls with the addition of zinc oxide nanoparticles. and the maximum solar cell efficiency utilizing Betalains dye was (η=1.626) for each concentration of the solar concentrator. Calculation of dye-free cell efficiency (η=0.500).
