A US research team has improved the efficiency of a blade-coated perovskite cell with a p-i-n structure by reducing iodine-induced charge traps in the films. They used the cells to fabricate a mini module with an efficiency of 18.2%.Scientists from the University of North Carolina have developed a perovskite solar cell with an efficiency of 23.2% by adding benzylhydrazine hydrochloride (BHC) as an iodine (I) reductant agent in precursor solutions such as methylammonium iodide (MAI) and formamidinium iodide (FAI). "Preventing the degradation of perovskite precursor solutions is equally important ...Den vollständigen Artikel lesen ...
