Nanomaterial Mixed with Dyes to Make Solar Cell Concentrator

In the present work, different concentrations of natural dyes (pomegranate, saffron, black lemon) were prepared by solving (0.001,0.002,0.003) g from these dyes in 100ml of pure water. The preparation of different concentrations mixed with the nanomaterial (titanium oxide) at a rate of 0.9 grams per 100 ml of pure water, in addition to mixing it with polymer epoxy resin at a ratio of 2:1 to obtain a solid mold after leaving it for two days to dry, and four solar cells were placed on the four different of the blocks which manufacture as solar cell concentrator. The best value for the efficiency of the solar cell was found for the pomegranate dye with a concentration of 0.002 grams, which is (ƞ=1.232), while the efficiency of the solar cell without dye is (ƞ=0.500).
