Luminous Solar Concentrates Using Natural Dyes Mixed With (Magnesium Oxide) Nanomaterial

Abstract

In this study, different concentrations (0.001,0.002,0.003) g of natural dyes (lemon, orange, beetroot) were prepared and dissolved in 100 ml of pure water because it does not affect the properties of the material and its absorption is very low in the visible spectrum. After preparing the concentrations, they were added in a square basin with four solar cells installed on its sides. 18 samples, first by the presence of a dye solution, and second by adding Mgo (Magnesium Oxide) nanomaterials at a ratio of 1.6 g  to each dye solution. The results showed that the absorption spectrum increases with increasing concentration, while the fluorescence spectrum increases with decreasing concentration. The results showed that all samples participated in raising the efficiency of the solar cell over the efficiency of the primary solar cell, but in varying proportions The percentage increase in the efficiency of the solar cell of lemon dye with magnesium oxide was (  ƞ= 1.912), and the efficiency of the basic solar cell was      (ƞ= 0.500).
