Abstract Lithium‐sulfur (Li‐S) batteries are one of the most promising next‐generation energy‐storage systems. Nevertheless, sluggish sulfur redox and shuttle effect in Li‐S major obstacles to their commercial application. Previous investigations on adsorption for LiPSs have made great progress but cannot restrain effect. Catalysts can enhance reaction kinetics, then alleviate The synergistic relationship between catalysis has become hotspot research into suppressing improving battery...
A lateral photodetector based on the bilayer composite film of a perovskite and conjugated polymer is reported. It exhibits significantly enhanced responsivity in UV–vis region sensitive photoresponse near-IR (NIR) at low applied voltage. This broadband also shows excellent mechanical flexibility improved environmental stability. As service to our authors readers, this journal provides supporting information supplied by authors.

Filterless narrowband response organic photodetectors (OPDs) present a great challenge due to the broad absorption range of semiconducting materials. The reported OPDs also suffer from low external quantum efficiency (EQE) in desired window and rejection ratio. Here, we report highly photomultiplication (PM) type based on P3HT:PC71BM (100:1, wt/wt) as active layer without an optical filter. full width at half-maximum (fwhm) PM-type can be well retained less than 30 nm under different biases....
In this work, an effectual strategy of constructing polar small molecule acceptors (SMAs) to promote fill factor (FF) nonfullerene polymer solar cells (PSCs) is first reported. Three asymmetrical SMAs IDT6CN, IDT6CN-Th, and IDT6CN-M, which own large dipole moments, are designed synthesized. The PSCs based on three exhibit apparently higher FFs compared with their symmetrical analogues. design accompanied side chain end group engineering makes IDT6CN-Th- IDT6CN-M-based achieve high power...
By integrating the advantages of materials and two binary PSCs into one cell, a PCE 13.73% is achieved in ternary PSCs.
Highly efficient ternary non-fullerene PSCs were fabricated employing PBDB-T as the donor and mixed ITCPTC:IDT6CN-M acceptors.
Abstract Nonfullerene polymer solar cells (PSCs) are fabricated by using one wide bandgap donor PBDB‐T and ultranarrow acceptor IEICO‐4F as the active layers. One medium PTB7‐Th is selected third component due to similar highest occupied molecular orbital level compared that of their complementary absorption spectra. The champion power conversion efficiency (PCE) PSCs increased from 10.25% 11.62% via incorporating 20 wt% in donors, with enhanced short‐circuit current ( J SC ) 24.14 mA cm −2...

Abstract The growing demand for lithium batteries with higher energy densities requires new electrode chemistries. Lithium metal is a promising candidate as the anode material due to its high theoretical specific capacity, negative electrochemical potential and favorable density. However, during cycling, low uneven ion concentration on surface of usually results in uncontrolled dendrite growth, especially at current densities. Here we tackle this issue by using lithiophilic montmorillonite...
Highly efficient ternary SMSCs with a PCE of 10.05% are reported by employing the nematic liquid crystal small molecule BTR as second donor and morphology regulator.
Abstract It is a great challenge to obtain broadband response perovskite photodetectors (PPDs) due the relatively large bandgaps of most used methylammonium lead halide perovskites. The range reported PPDs limited in ultraviolet–visible range. Here, highly sensitive are successfully fabricated with low bandgap (≈1.25 eV) (FASnI 3 ) 0.6 (MAPbI 0.4 as active layers, exhibiting from 300 1000 nm. performance can be optimized by adjusting thicknesses and C 60 layers. nm thick layer 70 exhibit an...

Herein, an emerging acceptor L8-BO as the third component was combined with B1:BO-4Cl system for constructing efficient ternary all-small-molecule organic solar cells (ASM-OSCs). Theoretical, morphological, and crystallographic studies reveal that BO-4Cl possess good compatibility, resulting in alloy-like state formation of two acceptors blends. The synergistic effect is conducive to forming favorable phase separation molecular stacking promoting charge splitting extraction, which...
Abstract Layer‐by‐layer all‐polymer solar cells (LbL all‐PSCs) are prepared with PM6 and PY‐IT by using sequential spin coating method.

In this study, less incorporated into enhance electrode. A power conversion (PCE) of 17.45% achieved LbL all‐PSCs incorporating 10 wt% layer, which much larger than 16.04% PCE...
The large non-radiative recombination is the main factor that limits state-of-the-art organic solar cells (OSCs). In this work, two novel structurally similar oligomers (named 5BDTBDD and 5BDDBDT) with D-A-D-A-D A-D-A-D-A configuration are synthesized for high-performance ternary OSCs low energy loss. As third components, these PM6 analogue effectively suppress in OSCs. Although highest occupied molecular orbital (HOMO) levels of 5BDDBDT higher than PM6, enabled ultra-high...
