The cell was used to build two perovskite solar modules with a size of 5x5cm and 10x10cm, respectively, and with efficiencies of 15.62% and 11.80%.Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) in Japan have fabricated a perovskite solar cell with an electron transport layer (ETL) based on high-quality large-area tin oxide (SnO2) films by using a chemical bath deposition (CBD) process with the addition of potassium permanganate (KMnO). The scientists explained that potassium (K) ions present in KMnO are able to diffuse into the perovskite material to ...Den vollständigen Artikel lesen ...
