Incorporation of a hole-transport material that also passivates surface defects results in perovskite solar cells with superior efficiency and stability.
Contact electrification between water and a solid surface is crucial for physicochemical processes at water-solid interfaces. However, the nature of involved remains poorly understood, especially in initial stage interface formation. Here we report that H
Oils are hydrophobic, but their degradation is frequently found to be accelerated in the presence of water microdroplets. The direct chemical consequences water–oil contact have long been overlooked. We show that aqueous microdroplets emulsified water–hexadecane (C16H34) mixtures can spontaneously produce CO2, •H, H2, and short-chain hydrocarbons (mainly C1 C2) as detected by gas chromatography, electron paramagnetic resonance spectroscopy, mass spectrometry. This reaction results from...

The stability of perovskite solar cells (PSCs) has been considered as one the major obstacles toward practical application. Defects in layer and ion infiltration from hole transport (HTL) can trigger degradation n-i-p PSCs. Herein, phenylhydrazine-4-sulfonic acid (PHPA) was employed an additive to modulate crystallization during film formation, enlarging crystal grain sizes ∼3 μm. Density functional theory (DFT) calculations revealed that PHPA could effectively inhibit formation iodine...
Water microdroplets (7 to 11 µm average diameter, depending on flow rate) are sprayed in a closed chamber at ambient temperature, whose relative humidity (RH) is controlled. The resulting concentration of ROS (reactive oxygen species) formed the microdroplets, measured by amount hydrogen peroxide (H 2 O ), determined nuclear magnetic resonance (NMR) and spectrofluorimetric assays after droplets collected. results found agree closely with one another. In addition, hydrated hydroxyl radical...
Hybrid organic-inorganic perovskites, especially methylammonium lead triiodide (MAPbI3 ), are intensely studied for their optoelectronic properties.
