Table 1 compares the optical and electrical properties of diffusive solar cell windows with various sizes and transmittance properties. Comparing windows 2 and 3 and 6 with 7, 10 and 11,
respectively reveals that a solar cell window that is fabricated using a nanocomposite plate with a higher haze percentage is more efficient. The scattered light intensity is proportional to both the volume and the concentration of the scattering particles. More light is scattered and directed to the solar cells that are mounted at the edges of the nanocomposite plate when the concentration of nanoparticles in the nanocomposite plate is higher, increasing the overall efficiency of the solar cell window. In actual applications, when a window curtain (such as white fabric) is placed under the light-guiding layer (glass), the solar light that penetrates the lightguiding layer is reflected by the white curtain and collected by the solar cells, further enhancing the efficiency of the window module from a minimum of 41% to a maximum of 71%. However, the view is then entirely blocked by the curtain.
