Chinese researchers have built a large-area perovskite PV panel that reportedly retains more than 90% of the initial efficiency after more than 850 hours. They used a hydrophobic, all-organic salt to modify the top surface of large-area, slot-die coated methylammonium-free halide perovskite layers.Scientists at Nanyang Technological University in China have fabricated a slot die-coated perovskite solar panel that reportedly offers remarkable efficiency retention. "Large area perovskite solar modules have issues with their stability due to intrinsic point defects and a mass of surface imperfections ...Den vollständigen Artikel lesen ...
