The collapse potential, mineralogy, microstructure, and particle morphology of a loess from the Loess Plateau, China, were characterized by double oedometer testing, X-ray diffraction, scanning electron microscopy with energy-dispersive spectroscopy, image analysis to elucidate origin its behavior. Results show that is highly collapsible maximum index 6.7% at vertical stress ∼200 kPa. deposit contains both nonclay (i.e., quartz, albite, muscovite, calcite) clay two chlorites) minerals....
Tin–lead (Sn–Pb) alloyed perovskites are promising candidates for next-generation photovoltaics due to their appropriate bandgaps multijunction tandem solar cells, which can potentially overcome the Shockley-Queisser limit. However, power conversion efficiency (PCE) and stability still impeded by poor absorber quality defects caused oxidation of Sn2+. Here, we introduced trimethylsulfoxonium iodide (TMSI) as an additive along with SnF2 fabricate Sn–Pb perovskite films enlarged grains...
The long exciton diffusion length (LD) plays an important role in promoting dissociation, suppressing charge recombination, and improving the transport process, thereby performance of organic solar cells (OSCs), especially thick-film OSCs. However, limited LD hinders further improvement device as film thickness increases. Here, organic-metal platinum complex, namely TTz-Pt, is synthesized served a solid additive into D18-Cl:L8-BO system. addition TTz-Pt enhanced crystallinity blends, reduced...
The growth of large semiconductor crystals is crucial for advancing modern electronics and optoelectronics. While various crystal techniques have been developed lead halide perovskites, a significant challenge remains: as size increases, performance tends to deteriorate dramatically. This study addresses the inherent limitations perovskite by designing novel strategy near-equilibrium system maintain optimal conditions throughout process. consists three independent units: solution supply...
A PCDTBT:PC<sub>71</sub>BM solar cell adopted by a ternary strategy with PDTSTPD achieves an overall PCE of 20.8% under indoor illumination.
Abstract Thick‐film all‐small‐molecule (ASM) organic solar cells (OSCs) are preferred for large‐scale fabrication with printing techniques due to the distinct advantages of monodispersion, easy purification, and negligible batch‐to‐batch variation. However, ASM OSCs typically constrained by morphology aspect achieve high efficiency maintain thick film simultaneously. Specifically, synchronously manipulating crystallinity, domain size, phase segregation a suitable level extremely challenging....
Indoor photovoltaics is of appealing application potential given the high limiting PCE 57%.
Organic photovoltaic (OPV) cells have shown effectiveness as off-grid power entities to drive the low consumption electronics among Internet of Things. The trap states and induced recombination in OPV are critically relevant performance but remain ambiguous for indoor application. Here, we investigate effects on by employing PBBD-T series donors wide bandgap acceptor BTA3. It is revealed that discrete density state introduces low-lying further aggravates trap-induced recombination. Instead...
Abstract All‐polymer solar cells (all‐PSCs) have received attention in recent years for their desirable properties power conversion efficiency and long‐term operational stability. However, it is still a big challenge to acquire an “ideal” vertical‐phase distribution of polymer/polymer blends due the non‐ideal molecular conformations mixing behaviors. Herein, ternary‐assisted sequential solution deposition (SSD) strategy adopted regulate vertical compositional profile all‐PSCs. A favorable...
Abstract Sn−Pb alloyed perovskites have drawn considerable attention because of their appropriate band gap for both single‐junction and multi‐junction tandem photovoltaics, but the easy‐formation energy disorder still limits practical applications. Here, we report that combination 1‐bromo‐4‐(methylsulfinyl) benzene (BBMS) SnF 2 greatly reduced Urbach perovskite films, largely restrained oxidation Sn 2+ . With help density functional theory calculations, clarified interactions between BBMS...
The “charge bridge” strategy is applied to organic photovoltaic devices, which dredges photocarrier trapping pathways by facilitating exciton–phonon decoupling. This benefit leads simultaneous improvement of efficiency and photothermal stability.
Abstract Near‐infrared organic photodetectors (NIR‐OPDs) have emerged as increasingly significant in optoelectronics, offering unparalleled advantages for applications health monitoring and night vision. The development of self‐powered devices with low dark currents enhanced NIR sensitivity involves complex engineering that requires careful material selection, defect state density control, environmental consideration.

Tuning the donor–acceptor (D–A) weight ratio is an essential step to optimize performance of a bulk heterojunction (BHJ) solar cell. The unoptimized regime with low acceptor concentration generally unexplored despite it may reveal early stage electronic D–A interactions. In this study, PTB7:PC 71 BM used examine factors that limit device in regime. key limiting factor creation traps and localized states originated from fullerene molecules.
