Light and PV solar panels

  1. Feb 16, 2015 #1
    Hi,
    I am wondering if all the different wavelengths (ie colors) of light are absorbed by a PV panel, and if so is the absorption equal among all the wavelengths? Is there any wavelength(s) that are more readily reflected off the glass or the PV cell itself?
    Thanks a lot!
    Scott

    Most PV cells have an anti-refelective coating, or are textured to prevent loss due to refelection. All wavelengths with energy greater than the band gap of the absorber material can be absorbed by a PV cell, however the charge carriers quickly thermalise losing a significant fraction of the energy absorbed (except in hot carrier solar cells).
