Accordingly, the aim of this study was to investigate the effect of rotation coating coating of europime (YVO4: Eu3 +) on the performance of silicon solar cell as a simple an‎d efficient method. For this purpose, two precursors obtained from powder synthesized by combustion synthesis method an‎d hydrothermal method were used to create a precursor solution for the coating process. First, two concentrated an‎d dilute solutions of YVO4 powder: Eu3 + combustion synthesis were deposited on the cell. The current-voltage density curves of the cells were measured an‎d the photovoltaic characteristics of the cells were determined. The results showed that despite the improvement of the conversion efficiency of solar cell power (from 8.97% in uncoated cell to 9.37% in thin coated cell), which resulted from the conversion effect of coating on the conversion of low wavelengths to wavelength. It was visible, the coating had a negative effect on the visible rays due to the lack of transparency. Then, with the aim of creating a transparent coating, the YVO4: Eu3 + precursor from the hydrothermal process was layered on the cell surface with three different concentrations by rotational lamination method. Fourier transform infrared spectroscopy (FT-IR) an‎d ultraviolet-visible absorption test were performed to characterize the cells. Current-voltage density curves showed that the coating created with medium concentration (diluted with 2 ml of water) had the best performance in improving the performance of solar cells so that the conversion efficiency of solar cell power in The presence of medium-concentration YVO4: Eu3 + film (hero cell) increased by approximately 5.6% (from 8.97% to 9.47%). It can be said that when coating with optimal concentration, the coating has performed its anti-reflective function as well as its reducing conversion function well. According to the results, it can be concluded that the hydrothermal method, due to its superior properties compared to the combustion synthesis method such as low operating temperature, is a more efficient method for producing YVO4: Eu3 + precursor suitable for layering a transparent coating on the surface. The solar cell is silicon. In summary, it is suggested that the layering of YVO4: Eu3 + as a reducing agent with easy an‎d low cost rotational lamination method can be a promising proposal to improve the performance of silicon solar cells.
