In this work, a solar concentrator was constructed using liquid crystalline material of the isotropic type to increase the efficiency of the solar cell. Two different concentrations of this liquid crystal were prepared and mixed with epoxy resin to manufacture the plates with an equal area of solar cell space. having Considered this kind of mixture, it was found that a high concentration of this material has contributed to increase the efficiency of the solar cell from 8.51 to 10.85, were also calculated the absorption, fluorescence spectra, short circuit current (Isc), open circuit voltage (Voc) and fill factor(FF). The quantum efficiency of fluorescence in this concentration was (93%, 90%).
