Alkali metal halide additives chelate with Pb<sup>2+</sup> ions during film formation promoting homogeneous nucleation, which greatly enhances the power conversion efficiency (15.08%) and stability (over 50 days) of planar perovskite solar cells.
Zr-based porphyrin metal–organic framework (MOF-525) nanocrystals with a crystal size of about 140 nm are synthesized and incorporated into perovskite solar cells. The morphology crystallinity the thin film enhanced since micropores MOF-525 allow crystallization to occur inside; this observation results in higher cell efficiency obtained MOF/perovskite cell. As service our authors readers, journal provides supporting information supplied by authors. Such materials peer reviewed may be...
With the aim of a reliable biosensing exhibiting enhanced sensitivity and selectivity, this study demonstrates dopamine (DA) sensor composed conductive poly(3,4-ethylenedioxythiophene) nanotubes (PEDOT NTs) conformally coated with porphyrin-based metal-organic framework nanocrystals (MOF-525). The MOF-525 serves as an electrocatalytic surface, while PEDOT NTs act charge collector to rapidly transport electron from MOF nanocrystals. Bundles these particles form interpenetrating network film...

To study relationship between morphology and performance, recorded scanning electron microscopy images...
Abstract In this study, hybrid perovskite solar cells are fabricated using poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and poly(3-hexylthiophene-2,5-diyl) (P3HT) as dopant-free hole-transporting materials (HTMs) two solution processes (one- two-step methods, respectively) for preparing methylammonium lead iodide perovskite. By optimizing the concentrations solvents of MEH-PPV solutions, a power conversion efficiency 9.65% with hysteresis-less performance is achieved,...
In this study, we have strategically designed and convergently synthesized two novel, symmetrical, linear A-D-A-type π-conjugated donor molecules (TBDTCNR, TBDTCN), each containing a planar electron-rich 2-octylthiene-5-yl-substituted benzodithiophene (TBDT) unit as the core, flanked by octylthiophene units end-capped with electron-deficient cyanoacetate (CNR) or dicyanovinyl (CN) units. We thoroughly characterized both of these materials investigated effects end groups (CNR, CN) on their...
Abstract To better understand the correlation of dielectric properties with photovoltaic response in conjugated polymer:fullerene bulk heterojunction materials, concept introducing minimal structural change is employed to increase polymer constant via polar cyano groups added end butyl or octyl side chains poly(dithienosilole‐thienopyrrolodione) system. Density functional theory calculations confirm that do not affect electronic structure but can lead an overall dipole moment depending on...
Ferroelectric Hf0.5Zr0.5O2 (HZO) thin films emerge as promising candidates for next-generation memory devices; however, the device performance is strongly correlated to interfacial structure. In this study, neutron reflectivity was used first time conduct an in-depth analysis of ferroelectric W/HZO/W devices, leveraging high sensitivity scattering length density (SLD) buried interfaces. We explored impact different atomic layer deposition (ALD) techniques─thermal, plasma, and annealing...

In this study, we used high-energy grinding to prepare solutions of well-dispersed transition metal oxides (TMOs), allowing the fabrication crystalline TMO films with high surface coverage through solution processing without post-annealing. Moreover, because solution-based method did not require surfactants, it preserved intrinsic electronic and optical properties TMOs. The resulting smooth, continuous, highly transparent were readily integrated into organic solar cells. After incorporating...

The nanomorphology of bulk heterojunctions (BHJs) plays a critical role in determining the performance non-fullerene organic solar cells (OSCs). Thermal annealing is commonly used to reorganize donor and acceptor phases within BHJs.
