Vacuum evaporation is promising for the high-throughput fabrication of perovskite solar cells (PSCs) because its solvent-free characteristic, precise control film thickness, and compatibility with large-scale production. Nevertheless, power conversion efficiency (PCE) PSCs fabricated by vacuum lags behind that solution-processed PSCs. Here, we report a Cl-containing alloy–mediated sequential approach to fabricate films. The presence Cl in alloy facilitates organic ammonium halide diffusion...
In inverted perovskite solar cells (PSCs), the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) is a widely used electron transport material. However, high degree of energy disorder and inadequate passivation PCBM limit efficiency devices, severe self-aggregation unstable morphology lifespan devices. Here, we design series dyads FP-Cn (n = 4, 8, 12) to replace as an layer, where [60]fullerene linked with terpyridine chelating group via flexible alkyl chain different...
Carbon capture, utilisation and storage (CCUS) is of unique significance for building a green resilient energy system, it also key solution to tackle the climate challenge. The concept supersonic decarburization, joint product non-equilibrium condensation swirling separation, can contribute CCUS technology in clean way. In this paper, numerical model established validated investigate complex physical phenomena decarbonization high-pressure environment based on real gas equation state....
Organic-inorganic hybrid perovskites exhibit outstanding performances in perovskite solar cells (PSCs). However, the complex solution chemistry of precursors renders it difficult to prepare large-area devices a reproducible way, which is prerequisite for technology make an impact beyond lab scale. Vacuum processing, instead, established large-scale coating thin films. with respect highly challenging due high vapor pressure organic ammonium halide. In this work, vacuum evaporation lead iodide...
Abstract Low-dimensional lead-free metal halide perovskites are highly attractive for cutting-edge optoelectronic applications. Herein, we report a class of scandium-based double perovskite crystals comprising antimony dopants that can generate multiexcitonic emissions in the ultraviolet, blue, and yellow spectral regions. Owing to zero-dimensional nature crystal lattice minimizes energy crosstalk, different excitonic states be selectively excited by ultraviolet light, X-ray irradiation,...
The corrosion behavior and passive film properties of CrMnFeCoNi CrFeCoNi coatings in 0.5 mol/L H2SO4 solution were investigated by potentiodynamic potentiostatic measurements, electrochemical impedance spectroscopy Mott-Schottky tests. chemical compositions characterized X-ray photoelectron (XPS). Results indicated that coating possessed lower current density, higher polarization resistance, donor acceptor density compared with coating, which determined has resistance than coating....
Abstract Lithium incorporation in kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) materials has been experimentally proven effective improving electronic quality for application photovoltaic devices. Herein, a feasible and solution‐based lithium post‐deposition treatment (PDT), enabling further efficiency improvement on the high‐performance baseline is reported dominant mechanism this proposed. In way, uniformly incorporated into grain interiors (GIs) without segregation at boundaries (GBs), which can...
Possessed with advantageous optoelectronic properties, perovskites have boosted the rapid development of solution-processed solar cells. The performance perovskite cells (PSCs) is significantly weakened by carrier loss at grain boundary grooves (GBGs); however, it receives limited attention and there lacks effective approach to solve this issue. Herein, for first time, we constructed tungstate/perovskite heterointerface via a "two step" in situ reaction that provides defect passivation...
Abstract Developing high‐performance polarization‐sensitive ultraviolet photodetectors is crucial for their application in military remote sensing, detection, bio‐inspired navigation, and machine vision. However, the significant absorption visible light range severely limits of photodetectors, such as high‐quality anti‐interference imaging. Here, based on a wide‐bandgap organic semiconductor single crystal (trans‐1,2‐bis(5‐phenyldithieno[2,3‐b:3′,2′‐d]thiophen‐2‐yl)ethene, BPTTE),...
Abstract Flexible perovskite solar cells often experience constant or cyclic bending during their service life. Catastrophic failure of devices may occur due to the crack polycrystalline films and delamination at substrate interfaces, posing a significant stability concern. Here, multiple dynamic hydrogen bonding polymer network is developed enhance mechanical strength flexible in two ways. The main chain poly(acrylic acid) decreases mismatch coefficient thermal expansion between by 16.7%...
Abstract The performance of kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cell is known to be severely limited by the nonradiative recombination near heterojunction interface and within bulk CZTSSe absorber resulting from abundant centers carrier collection efficiency.
