I am searching for a material to improve the efficiency of solar panel. Any good literature known to you. Please send to me.Thanks
You can generally optimise coatings as non-reflective coatings by looking at two materials and two geometry problems:
a) dielectric constant (refractive index matching),
b) surface plasmonic coupling in case of metals,
c) thickness (destructive interference at about quarter wavelength thickness for vertical incidence, as in a Fabry-Perot interferometer) and
d) lateral structuring (destructive interference for non-vertical incidence).
Adding to Thomas and coming to the point you can use antireflection coatings. For more information please see the paper in the Link:Fig. 2. http://www.photoptech.com/main/products_gx/pdf/Coating/Antireflection%20Coating.pdf
You could also think of radiation converting coatings. For each type of solar cells there are certain wavelengths in the solar spectrum either too short or too long to be efficiently absorbed and used for generation of charge carriers. It is at least theoretically possible to convert this "awkward" photons to the range of high efficiency of the solar cell by using down-converting or up-converting luminescent materials. You can easily find papers on that by googling the keywords or can take some details from my article on nanophosphor coatings (see Section "Applications")
