Anorganische CsPbX3‐Perowskit‐Solarzellen: Fortschritte und Perspektiven

Abstract: + + ]D ie Autoren haben zu gleichen Teilen zu dieser Arbeit beigetragen. Die Identifikationsnummern (ORCID) der Autoren sind unter https://doi.org/10.1002/ange.201901081 zu finden.Perowskite auf Halogenidbasis haben sicha ufgrund ihrer hervorragenden optoelektronischen Eigenschaften zu einem der wichtigsten Themen in der Photovoltaik-Forschung entwickelt. Insbesondere wurden bei organisch-anorganischen Perowskit-Solarzellen (PSCs) rasche Fortschritte beim Wirkungsgrad (PCE, power conversion efficiency) erreich… Show more

“…[8] Aiming for improved stability,all-inorganic (CsPbX 3 , X = I À ,B r À ,o rC l À )p erovskites free of volatile components by replacing the organic MA + or FA + species with inorganic Cs + have been widely studied for alternative light absorbers. [9,10] Among them, tri-brominated CsPbBr 3 shows superior environmental tolerance even in 90 %h umidity,b ut their photovoltaic performances are still sluggish owing to the substantial charge losses and dilatory photogenerated charge diffusion. [11,12] Although the energy band engineering is prevalent to accelerate charge separation, [13] the state-ofthe-art hole transporting materials (HTMs) are generally organic species,s uch as spiro-MeOTAD, PTAA, or P3HT, which will introduce new hazards (hygroscopic additives,o r light/thermal instability) and subsequently degrade the cell efficiency, [14,15] against the establishment of all-inorganic PSCs.T herefore,h ow to promote the charge separation without sacrificing the excellent stability is an urgent projection for further PSC platforms.…”
