"As described above, an energy conversion film and a quantum dot film according to the present invention can block solar light of unnecessary regions and converts the blocked light into electrically useful visible light. In particular, when the energy conversion film and the quantum dot film can be effectively used as energy conversion layers in solar cells or the like. Solar cells prepared using these films have high light conversion efficiency and are light in weight, and thus can be efficiently in general applications as well as in applications related to the space industry."
