Researchers Develop Economical, Eco-friendly Fabrication of Solar Cells
INCHEON, South Korea—Researchers at Incheon National University have developed a cost-effective, eco-friendly technique for making high-efficiency chalcopyrite solar cells.
Their technique involves aqueous spray deposition of materials in a standard atmosphere and does not require vacuum. This novel approach yields a relatively high power conversion efficiency of more than 17 percent.
