Use Liquid Crystals to Enhance the Efficiency of the PV

Solar cells are a promising technology for energy production, and they provide a sustainable and environmentally friendly alternative to traditional energy sources based on fossil fuels. This study aims to improve the efficiency (E)of the solar cell using Triglyceride for Oleic Acid. Crystal Triglyceride for Oleic Acid is a compound of two components (Triglyceride and Oleic Acid), Each compound has a structural formula and physical and chemical properties. The prepared samples (1, 1.4, 1.5, 1.6, and 2) mol/l. The required data were collected and analyzed through (a UV/visible spectrophotometer, Spectrofluorometer, and Solar Module Analyzer), The data obtained were wavelength for absorption, wavelength for fluorescence, Stokes shift (the difference between fluorescence and absorption wavelengths), practical and theoretical efficiency, current and voltage values, and power factor. Luminescent solar concentrators were used to test the efficiency of the PV. The results showed that the E improved well, as the efficiency was (21.57) before using the solar concentrator, and after using the concentrator, it became (26.61) at a concentration of 1.5 mol/l.
