Raising the efficiency of polycrystalline cells with new luminescent EVA film

Chinese researchers have developed a pure EVA film which they claim can enhance the conversion efficiency of conventional crystalline solar cells by around 0.50%. The film is able to convert UV light into strong visible light.Researchers at China's Hebei University of Technology have developed a luminescent ethylene-vinyl acetate (EVA) copolymer film that is said to have the potential to raise the efficiency of conventional polycrystalline solar cells by around 0.50%. The scientists affirmed that the pure film has a high thermal stability, which was demonstrated under light-soaking test for 500 ...
