Perovskite solar cells (PSCs) are being rapidly developed at a fiery stage due to their marvelous and fast-growing power conversion efficiency (PCE). Advantages such as high PCE, solution processability, tunable band gaps, flexibility make PSCs one of the research hot spots in energy field. Flexible (f-PSCs) owing power-to-weight ratios can be promising candidates serve sources mobile systems, space portable functional devices, so on. Herein, we give review on recent progress f-PSCs...
With the rapid rise in perovskite solar cells (PSCs) performance, it is imperative to develop scalable fabrication techniques accelerate potential commercialization. However, power conversion efficiencies (PCEs) of PSCs fabricated via two-step sequential deposition lag far behind state-of-the-art spin-coated ones. Herein, additive methylammonium chloride (MACl) introduced modulate crystallization and orientation a doctor-bladed film ambient conditions. MACl can significantly improve quality...
The linear dichroism (LD) transition within anisotropic photonic materials displays promising prospects for applications in polarization-wavelength-selective detectors, optical switching, and communication. In conventional two-dimensional (2D) materials, the LD is predominantly uniaxial over a broad spectrum of wavelengths arises principally from reduced symmetry materials. However, behavior crystalline 2D remains elusive. Here, we demonstrate observation unique conversion phenomenon at...
Abstract Flexible perovskite solar cells (f‐PSCs) have been attracting tremendous attention due to their potentially commercial prospects in flexible energy system and mobile system. Reducing the barriers charge extraction losses at interfaces between transport layers is essential improve both efficiency stability of f‐PSCs. Herein, 4‐trifluoromethylphenylethylamine iodide (CF 3 PEAI) introduced form a 2D interface hole layer (HTL). It found that plays dual‐functional role aligning band HTL...
Abstract Mixed‐cation perovskite solar cells (PSCs) have attracted much attention because of the advantages suitable bandgap and stability. It is still a challenge to rationally design modify perovskite/tin oxide (SnO 2 ) heterogeneous interface for achieving highly efficient stable PSCs. Herein, strategy one‐stone‐for‐three‐birds proposed achieve multi‐functional regulation via introducing N‐Chlorosuccinimide (NCS) into solution SnO : i) C═O functional group in NCS can induces strong...
Perovskite solar cells (PSCs) have emerged as one of the most promising and competitive photovoltaic technologies, doctor-blading is a facile robust deposition technique to efficiently fabricate PSCs in large scale, especially matching with roll-to-roll process. Herein, it demonstrates encouraging results one-step, antisolvent-free doctor-bladed methylammonium lead iodide (CH3 NH3 PbI3, MAPbI3 ) under wide range humidity from 45% 82%. A synergy strategy ionic-liquid acetate (MAAc) molecular...
Interfacial defects greatly influence the performance of perovskite solar cells (PSCs), and interface engineering is a powerful technique to promote power conversion efficiency (PCE) PSCs. Herein, an interfacial passivation strategy developed employing cesium fluoride (CsF) modify surface film. Theoretical calculations suggest that Cs+ F− ions have targeted effect decrease defect density perovskite. Meanwhile, Cs+-formamidine+ (FA+) F−–I− ion exchange can occur on surface, which leads...
Abstract The phase structure, crystallization and melting behavior of high density polyethylene (HDPE) blends with hydrogenated petroleum resin P-100 were investigated by polarized optical microscopy (POM), scanning electron (SEM) differential calorimetry (DSC). Results indicated that the structures had a three-dimensional bi-continuous network. network sizes depended on composition conditions, when quenched or cooled down slowly below temperature HDPE from molten state; decreased both...

The nonlocal spin valve configuration consists of two ferromagnetic and nonmagnetic channels, which is an effective for determining injection accumulation. Here, we report that a reversed signal was detected by changing the voltage probe configurations in graphene (Py/MgO/graphene/MgO/Py) lateral valves. abnormal spin-dependent attributed to nonuniform pinhole at interface low-resistance tunnel barrier, makes charge current flow through detection electrode return channel. We demonstrate...
Time-resolved simultaneous synchrotron small-angle X-ray scattering and differential scanning calorimetry experiments have been performed on crystallization of polyethylene-polyisoprene diblock copolymers (HEI or LEI) their blends with corresponding homopolymers, polyethylene (PE) polyisoprene (PIp).
