Effect of transparent conducting oxides on the temperature of the optical fiber cable

Abstract

     The aim of this study is to show the effect of thin layers of transparent conducting oxides on the temperature of the glass fiber optic cable that transmits concentrated solar radiation using the center of the solar parabol,In this study we selected a thin layer of tin oxide and applied it on the surface of a fiberglass optical cable section, and this is done by determining the optical properties of the thin layer of tin oxide and the properties of the glass fiber optic cable, as well as the solar radiation taken on a specific day and hour in the wilaya of Ouargla from the city of Algeria.After setting the hypotheses and the mathematical model, we obtained equations that we programmed using the MATLAB program, and we obtained results that we analyzed and compared with previous theoretical results for the glass fiber cable without placing the thin layer of tin oxide.The obtained results showed that the surface temperature of the cable section has the lowest value at 750 nm wavelength of solar radiation and at a thickness of 1.13 µm for the tin oxide thin layer.We also found that the surface temperature of the cable section using a thin layer of zinc oxide with a certain thickness at the surface of the cable section is lower than the temperature recorded at the surface of the cable section at the same thickness in the case of using a thin layer of tin oxide.In addition, the surface temperature of the cable section at a certain thickness in the case of using a thin layer of zinc oxide, which is inlaid, is lower than the temperature recorded at the surface of the cable section in the case of using a thin layer of pure zinc oxide at the same thickness.
