Abstract Traditional methods of discovering new materials, such as the empirical trial and error method density functional theory (DFT)‐based method, are unable to keep pace with development materials science today due their long cycles, low efficiency, high costs. Accordingly, its computational cost short cycle, machine learning is coupled powerful data processing prediction performance being widely used in material detection, analysis, design. In this article, we discuss basic operational...

Abstract Although planar‐structured perovskite solar cells (PSCs) have power conversion efficiencies exceeding 24%, the poor photostability, especially with ultraviolet irradiance (UV) severely limits commercial application. The most commonly‐used TiO 2 electron selective layer has a strong photocatalytic effect on perovskite/TiO interface when is excited by UV light. Here UV‐inert ZnTiO 3 reported as in planar PSCs. perovskite‐structured semiconductor excellent chemical stability and...
The buffer is an essential component that connects the window and absorber layers in thin film solar cells, which has significant impacts on performance of cell device. CdS widely used material, but it drawbacks toxicity narrow band gap 2.4 eV. This work explores fabrication a novel Cd-free MgZnS layer through co-sputtering ZnS Mg targets. grain size, morphology, phase composition, transmittance films are manipulated by adjusting substrate temperature, sputtering power target current target....
Perovskite solar cells (PSCs) with power conversion efficiencies (PCEs) of 25 % mainly have SnO2 or TiO2 as electron-transporting layers (ETLs). Now, zinc titanate (ZnTiO3 , ZTO) is proposed mesoporous ETLs owing to its weak photo-effect, excellent carrier extraction, and transfer properties. Uniform films were obtained by spinning coating the ZTO ink annealed below 150 °C. Photovoltaic devices based on Cs0.05 FA0.81 MA0.14 PbI2.55 Br0.45 perovskite sandwiched between -mesorporous electrode...
Sb 2 Se 3 was incorporated into precursor films. During annealing, decomposes, releasing and Se, which provides the necessary energy for grain growth through mass transport at boundaries, thereby promoting performance of solar cells.
Abstract The cost‐effective commercialization of perovskite solar cells (PSCs) requires eliminating the dependency on a strictly controlled atmosphere during their fabrication process. However, this remains significant challenge due to high sensitivity crystallization process humidity. Here, synergistic effects residual solvent and environmental humidity films are studied. water‐solubility volatility isopropanol (IPA) in precursor film major contributions water poor control over A...
Multifunctional core-shell nanocarriers based on zinc oxide (ZnO)-gated magnetic mesoporous silica nanoparticles (MMSN) were prepared for cancer treatment through targeting and pH-triggered controlled drug release. Under an external field, the MMSN could actively deliver chemotherapeutic agent, daunomycin (DNM), to targeted sites. At neutral aqueous, functionalized stably accommodate DNM molecules since mesopores capped by ZnO gatekeepers. In contrast, at acid intercellular environment,...
The dose-dependent toxicity and low specificity against cancerous cells have restricted the clinical use of daunomycin (DNM). Titanium dioxide (TiO2) has been wildly used as an inorganic photodynamic therapy (PDT) agent drug carrier. To facilitate targeted delivery combined therapy, in present study, TiO2-coated Fe3O4 nanoparticles (Fe3O4@TiO2 NPs) were employed to load DNM drug-loaded Fe3O4@TiO2-DNM Nps exhibited smart pH-controlled releasing satisfactory cytotoxicity well photocytotocity....
Condensed droplets on different nano-textured surfaces may appear in three distinct wetting states, the Cassie–Baxter state with composite wetting, Wenzel complete and partially wetted (PW) state. To maintain super-hydrophobicity of a textured surface, condensed drops it are usually expected to be or PW Therefore, is importance clarify relation between droplet states nano-pillar geometries surfaces. In view fact that all diverse originate from nuclei and/or condensate spots growing along...

The rise of perovskite solar cell performance lies in the increase fill factor and open-circuit voltage, which depend on high film quality (shunt resistance) efficient charge transportation (series resistance). Polymer passivation could suppress defects, while its poor conductivity leads to a trade-off between series resistance. Here we introduce polymer network modified mesoporous SnO2 layer reconcile this contradiction, was partially coated by polymer. Electrons can be extracted through...
Magnetic mesoporous silica nanospheres (MMSN) were prepared and the surface was modified with cancer cell-specific ligand folic acid. Calcium carbonate then employed as acid-activated gatekeepers to cap mesopores of MMSN, namely, MMSN-FA-CaCO 3 . The formation proved by several characterization techniques, viz. transmission electron microscopy, zeta potential measurement, Fourier transform infrared spectroscopy, BET area UV–Vis spectroscopy. Daunomycin successfully loaded in system exhibited...
