Abstract: A window for a greenhouse is provided that is comprised of a sheet of luminescent material [104] and light-energy converter [103]. The sheet comprises one or more luminescent materials [104] that absorb the peak wavelengths of the sun, emitting the absorbed photons to wavelengths primarily between 600 and 690 nm where they are converted to electrical power and/or enhance plant production. The luminescent material [104] is also transparent to a fraction of the wavelengths in the blue and red-portion of the solar spectrum which are required for plant growth and flowering. An additional polymer layer may be added as a luminescent layer, diffuser and/or IR reflector to further enhance plant growth and electricity generation.
