دراسة تأثير مادة TiO2 على انعكاسية الخلية الشمسية نوع GaAs

Abstract EN

This work includes a theoretical study to the effect of TiO2 material on reflectance of the GaAs solar cell.

Many designs were suggested by adding TiO2 material on the solar cell, in first design TiO2 material was deposited above the solar cell and in the second design TiO2 material was deposited under solar cell whereas in the third design the solar cell haven’t TiO2 layer, the reflectance of various designs were calculated by depending on the characteristic matrix theory to obtain optimum design of lowest value of reflectance.

It was found that the best design when the TiO2 layer was deposited above GaAs solar cell and when the optical thickness not equal to the quarter of wavelength (Non QWT) in which its reflectance at wavelength design reach up to (7.18E-12).
