Abstract Increasing the power conversion efficiency (PCE) of two‐dimensional (2D) perovskite‐based solar cells (PVSCs) is really a challenge. Vertical orientation 2D perovskite film an efficient strategy to elevate PCE. In this work, vertically orientated highly crystalline (PEA) 2 (MA) n–1 Pb n I 3n+1 (PEA= phenylethylammonium, MA = methylammonium, 3, 4, 5) films are fabricated with assistance ammonium thiocyanate (NH 4 SCN) additive by one‐step spin‐coating method. Planar‐structured PVSCs...
Thiocyanate ammonium additives are found to improve the performance of FAPbI<sub>3</sub> based planar perovskite solar cells through a single one-step method.
Small bandgap 2D perovskites were synthesized with desired orientation and the corresponding solar cells presented high efficiency good stability.
Abstract Herein three polymeric hole extraction materials (HEMs), poly(benzene‐dithiophene) (PB2T)‐O, PB2T‐S, and PB2T‐SO are presented for p–i–n perovskite solar cells (PVSCs). This study reveals that the device hysteresis performance heavily rely on grain boundary conditions. More specifically, they predetermined through molecular interaction between Lewis base atoms of HEMs perovskites. It is revealed only changing side chain terminals (OCH 3 , SCH SOCH ) results in effective...
The NAC gene family is of great value for plant stress resistance and development. In this study, five genes with a typical NAM domain were isolated from Salix psammophila, which stress-resistant willow endemic to western China. Two hundred sixty-two purpurea, Arabidopsis used construct the phylogenetic tree examine relationship. Five in psammophila focus bioinformatics analysis conserved structural analysis. SpsNAC005 was overexpressed Populus hopeiensis, transgenic lines subjected salt...
This study proposes a multi-mode switching control strategy based on electromagnetic hybrid suspension (EMHS) to achieve the best relationship possible between vehicle’s vibration reduction performance and energy consumption. The working modes of EMHS are divided into active, semi-active, recovery according root mean square weighted acceleration human subjective sensation. two key parameters analysis sampling interval judgment times introduced optimize conditions reduce deterioration comfort...
This paper takes a cross section of 6 × 7 + IWS wire rope as an example to complete the studies on method geometric modeling for no‐joint and implementation 3D solid model. Frenet–Serret frame theory establishes three types frame, which are double‐helix winding straight line, single‐helix arc, it allows derivation eight center line equation wire. has ascertained tangent condition lines steel wires with same name between arc straight‐line closed rope. It been concluded that length must be...
This study proposes a variable weight model prediction control strategy based on road surface recognition (VW-MPC-RSR), aiming to address the problems of timeliness and (MPC) adjustment under multi-working conditions. The is achieved by utilizing VIT-B/16 network model. A test set continuous frame video are used verify effectiveness strategy. At same time, 2-DOF suspension dynamics established, MPC designed. optimal weights six types determined using cross-comparison method, corresponding...
Traditional energy-feeding suspensions exhibit a non-adjustable damping characteristic during energy recovery, which can compromise the dynamic performance of suspension system. To overcome this issue, paper proposes an variable control strategy (EFVD) predicated on electromagnetic hybrid This aims to achieve adjustable reducing losses while ensuring optimal performance. Building half-vehicle model, we construct model suspension. By leveraging enhanced hybrid-skyhook and ground-hook...
A numerical technique employing the method of moments (MOM) and physical optics (PO) is presented for studying scattering from a planar slotted waveguide array antennas. The slot calculated by MOM. Special attention paid to evaluation admittance matrix elements, which involve internal external mutual coupling. structural solved using PO. Numerical results are given demonstrate effects several factors including number basis functions , thickness on radar cross section (RCS) array. As check...
Steering Angle is related to the design and optimization of steering mechanism suspension, but it not equal angle knuckle around kingpin because existence wheel alignment parameters. To calculate angle, this paper derives based on homogeneous transformation its function expression by analyzing spatial geometric relation between two angles calculating coordinates trajectory center. Then, multi-body model McPherson suspension with system built calculation correctness verified comparing curve...
A wideband conical log spiral antenna is proposed in this communication. The composed of two arms that are wrapped around each other a log-periodic manner. It excited by microstrip feed printed on the opposite side substrate having dielcetric constant 2.65 and thickness 1mm, which regard as balun, providing with appropriate impedance matching between arms. parametric study performed for practical design guidelines. simulation results indicate an bandwidth VSWR ≤ 2.0 from 3.2GHz to 7GHz...
