Europium ions have been used by Chinese researchers to passivate both the perovskite and electron transport layer (ETL) films of a MAPbI3 perovskite solar cell. As a result, the device's efficiency was raised by approximately 1.5%. The dual passivation approach also achieved an increase in the cell's fill factor and open-circuit voltage.Scientists from the Shaanxi Normal University in China have fabricated a perovskite solar cell based on methylammonium lead iodide (MAPbI3) through a dual passivation technique that simultaneously passivates trap defects in both the perovskite and electron transport ...Den vollständigen Artikel lesen ...
