The invention provides highly fluorescent materials comprising a single (i=0) or a series (i=1, 2, etc.) of heterocyclic systems. The chromophores are particularly useful for absorption and emission of photons in the visible and near infrared wavelength range. The photo-stable highly luminescent chromophores are useful in various applications, including in wavelength conversion films. Wavelength conversion films have the potential to significantly enhance the solar harvesting efficiency of photovoltaic or solar cell devices.

Described herein are wavelength conversion films which utilize photostable organic chromophores. In some embodiments, wavelength conversion films and chromophores exhibit improved photostability. In some embodiments, a wavelength conversion film comprising luminescent compounds is useful for improving the solar harvesting efficiency of solar cells, solar panels, or photovoltaic devices. In some embodiments, a wavelength conversion film comprising multiple luminescent compounds is useful for greenhouse roofs. Some embodiments provide an improved solar light wavelength profile for improved plant nutrition and/or growth.
