Semi-transparent organic photovoltaics for greenhouse applications
Scientists from the University of California, Los Angeles (UCLA), have used an antioxidant known as L-glutathione as an interlayer in an organic PV cell to prevent other materials from oxidizing. The cell has an efficiency of 13.5% and an average visible transmittance of 21.5%. The researchers said it is suitable for applications in solar greenhouses.
