Chicory or the so-called in Egypt Al-serees is found in a large quantities of agricultural clover and vegetables. The present study investigates the methanolic extract 70% of Cichorium intybus L belonging to family Asteraceae. Data obtained from the elemental analysis revealed the presence of 23 elements. The major detected elements are Sodium) Na( 159.59 ppm, potassium )K( 19.29 ppm, Calcium  )Ca( 8.68 ppm, Magnesium) Mg( 6.88 ppm and Aluminium )Al( 3.11ppm respectively. The metallic nanoparticles are traditionally synthesized by wet chemical techniques with potassium chloride. The formation of potassium chloride nanoparticles was confirmed by X-Ray Diffraction, (XRD). The XRD pattern indicates that the nanoparticles had cubic structure. The XRD analysis of potassium chloride (KCl) nanoparticles have five peaks at 28.39, 40.58, 50.25, 58.75 and 66.47 angles. At 28.39 = 2θ, the curve has the extra highest peak. The average crystallite size for KCl as observed from XRD spectral analysis was found to be 20 nm, which is in agreement with the Transmission Electron Microscpe (TEM) analysis. The Scanning Electron Microscope (SEM) analysis shows the spheric potassium chloride and other minerals  nanoparticles.The potassium chloride  and other elements nanoparticles may be used to improve the performance of photovoltaic solar cell. The selection of chicory (Al-serees ) is due to a cost effective and environmental friendly technique
