Chalcogenide perovskites constitute a promising earth-abundant, non-toxic, and robust semiconductor family with the potential to compete hybrid as high-quality photovoltaic absorbers. However, low-temperature, solution-based synthesis route has eluded researchers in this area. Here we report colloidal of chalcogenide perovskite BaZrS3 nanoparticles at 330 °C organic solvent. The (10-20 nm) are found be comprised smaller (3-5 crystalline domains. Promising optoelectronic properties for...
Chalcogenide perovskites have attracted increasing research attention in recent years due to their promise of unique optoelectronic properties combined with stability. However, the synthesis and processing these materials has been constrained by need for high temperatures and/or long reaction times. In this work, we address open question a low-temperature growth mechanism BaZrS3. Ultimately, liquid-assisted BaZrS3 using molten BaS3 as flux is demonstrated at ≥540 °C little 5 min. The role...
There has been a long-running debate about reinforcement and rheological nonlinearity of suspensions with respect to filler dispersity agglomeration depending on many factors, including molecular weight dispersing medium, surface chemistry nanoparticles, aging suspensions. Herein, behaviors fumed silica suspended in polydimethylsiloxane (PDMS) were investigated as function averaged (Mw, 2–88 kg/mol) PDMS, concentration characteristics (hydrophilic or hydrophobic) silica. The at low-frequency...
Immobilized polymer fractions have been claimed to be of vital importance for sol-gel transitions generally observed in nanoparticle dispersions but remain a matter debate regarding mechanism and difficulty prediction. Here we investigate the immobilized layer structures trifunctionality polyether polyol (PPG) near surfaces hydrophilic hydrophobic fumed silica (FS) nanoparticles reveal role surface chemistry on molecular dynamics dispersions. Using modulated differential scanning...
Chalcogenide perovskites have gained recent research attention as a promising semiconductor for photovoltaic and optoelectronic applications. In addition to the challenges that surround synthesis processing of these materials into devices, their phase stability in perovskite structures is an open question. Reported syntheses presently lack clear criteria. this work, we present compelling analysis sulfide ABS3 selenide ABSe3 compounds on basis ionic radii electronegativity arguments. This...
The influence of nanosilica on the concentration fluctuation polystyrene/poly (vinyl methyl ether) (PS/PVME) mixtures was investigated during phase separation. amplitude quantified by dielectric spectrums based idea Lodge–Mcleish model and linearized Cahn–Hilliard theory could describe evolution at early stage Hydrophilic A200 dispersed in PVME-rich behaved an obvious inhibition effect blend matrix, while hydrophobic R974 PS-rich had little fluctuation. kinetics separation for PS/PVME/A200...
Remarkable progress in photovoltaic has been made by the halide perovskites, paving way for overcoming Shockley-Queisser-limit of 33.7 % a single junction solar cell tandem applications. However, biggest challenge commercialization is stability perovskites which are rather prone to degradation through air, light, heat, and electric field mechanisms. Alternatively, highly stable chalcogenide perovskite materials, containing S, Se instead halides might maintain their remarkable optoelectronic...
