The 5x5cm device was developed by a Japanese research group. The thickness of the perovskite films was increased to reduce defects and pinholes and this was achieved by adding ammonium chloride to the lead iodine solution used in the formation of the films. The device was able to work for 1,600 hours at more than 80% of this efficiency.A research group from the Okinawa Institute of Technology (OIST) in Japan has developed a mini perovskite solar module based on large-area uniform and dense perovskite films with a thickness of more than one-micrometer. The scientists fabricated two modules, sized ...Den vollständigen Artikel lesen ...
