Bright and fast-response perovskite light-emitting diodes with an ICBA:modified-C₆₀ nanocomposite electrical confinement layer

Abstract

Bright and fast-response CH3NH3PbBr3 perovskite light-emitting diodes (PeLEDs) are realized by using ICBA:modified C60 (MC60) nanocomposites as the hole blocking layer (HBL) and electron transport layer (ETL).

Stable and efficient soft perovskite crystalline film based solar cells prepared with a facile encapsulation method

“…In recent decades, organic-inorganic lead tri-halide perovskite crystalline thin films have been widely used as the active layers of various devices, such as solar cells, 1-3 light-emitting diodes, [4][5][6] photo-detectors, [7][8][9] X-ray detectors [10][11][12] and fieldeffect transistors, [13][14][15] due to their tunable optoelectronic properties and low-cost fabrication methods. In the application of solar cells, CH 3 NH 3 PbI 3 (MAPbI 3 ) and CH 3 NH 3 PbBr 3 (MAPbBr 3 ) perovskite crystals were first deposited on the top of a mesoporous TiO 2 /FTO/glass substrate as a light absorber, which resulted in a moderate power conversion efficiency (PCE) of 3.8%.…”

Amplifying Hole Extraction Characteristics of PEDOT:PSS via Post-treatment with Aromatic Diammonium Acetates for Tin Perovskite Solar Cells

“…In both ETLs, simultaneous increases in V OC and J SC at ∼900 h are identified. However, ICBA seemingly resulted in the more prominent rises in J SC , which would be attributable to its high tolerance to the stressors by the hydrophobicity 46,47 and suppressed iodide doping. 43 Most importantly, the PCE of 4AMPY(Ac) 2 reached an impressively high value of 12.1% after ∼900 h (Figure 3j and Table S2), confirming the great potential of post-treatment for high-performance TPSCs.…”

Advancements in the stability, protection and lead-free strategies of perovskite solar cells: a critical review

“…The organic materials used as ETMs are polymer, phenyl-C 61 -butyric acid methyl ester (PCBM). When polymers are utilized as the ETL scaffold, they can offer ideal morphologies and high resistance to humidity to the perovskite absorber [55,56]. Inorganic materials typically exhibit superior thermal and long-term stability.…”
