Abstract Large datasets are now ubiquitous as technology enables higher-throughput experiments, but rarely can a research field truly benefit from the data generated due to inconsistent formatting, undocumented storage or improper dissemination. Here we extract all meaningful device peer-reviewed papers on metal-halide perovskite solar cells published so far and make them available in database. We collect over 42,400 photovoltaic devices with up 100 parameters per device. then develop...
Non-volatile memory devices based on resistive-switching with remarkable bipolar and bistable properties are fabricated from organic–inorganic lead halide perovskite nanoparticles at ambient conditions. Chloride doping to the basic structure is found have substantial effect operational parameters of devices. As a service our authors readers, this journal provides supporting information supplied by authors. Such materials peer reviewed may be re-organized for online delivery, but not...
Low temperature processed carbon-based perovskite solar cells (C-PSCs) have gained great interest because of low cost and ease fabrication. By replacing the Au electrode with carbon, stable suited for mass-production process can be made. However, power conversion efficiencies (PCEs) C–PSCs still lag behind that PSCs contact. Here we explore (≤150 °C) C-PSCs with, where a two-step method is used to prepare mixed-ion lead films, tin oxide (SnO2) electron transport layer,...
Scalable methods for deposition of lead halide perovskite thin films are required to enable commercialization the highly promising photovoltaics. Here, we have developed a slot-die coating process under ambient conditions methylammonium iodide (MAPbI3) on heated substrates (about 90 °C substrate surface). Dense, crystalline with large grains (100–200 μm) were obtained by careful adjustment parameters, using solutions that similar but more dilute than those used in typical spin-coating...
Slot-die coated tin oxide films are suited as electron transport layers in large-scale perovskite solar cells.
Dynamic features of a cavitating venturi have been topic investigation for the past few decades. This review presents state-of-the-art experimental and numerical studies in to address challenges understanding flow behavior developing reliable models. Many shown that two strongly coupled mechanisms, namely, Re-entrant Jet bubbly shock influence cavitation zone behavior. We provide pointers from recent geometry operating conditions, introducing changes cavity oscillation. From an operational...
Abstract Hybrid perovskites have created enormous research interest as a low‐cost material for high‐performance photovoltaic devices, light‐emitting diodes, photodetectors, memory devices and sensors. Perovskite materials in nanocrystal form that display intense luminescence due to the quantum confinement effect were found be particularly suitable most of these applications. However, potential use perovskite nanocrystals light‐harvesting antenna possible applications artificial...
Cavitating venturi is a passive flow rate anchoring device used in varied industrial applications. The dynamics of the cavitation zone can be interest to ascertain controlled operation cavitating under varying pressure ratios.

Quasi-steady experiments are conducted for ratio range 0.39–0.95 and an inlet Reynolds number 7.3 × 104–1.28 105. Shadowgraphy high-speed imaging obtain...
Low‐temperature‐processed carbon‐based perovskite solar cells (C‐PSCs) are promising photovoltaic devices, because of their good stability, low cost, and simple preparation methods, which allow for scalable processing. Herein, C‐PSCs with the n−i−p structure prepared, using a SnO 2 nanoparticles film as electron‐selective contact, MAPbI 3 intrinsic absorber layer (MA = methylammonium), carbon hole‐selective conductor. Carbon is, however, not an ideal it is found that improved cell...
Low‐temperature processed carbon‐based perovskite solar cells have received great attention due to low‐cost, high stability, and simple preparation processes that can be employed in large‐scale manufacturing. Carbon paste is deposited by techniques such as doctor blading or screen printing. However, solvents from this damage the underlying layers resulting poor performance of cells. Furthermore, carbon not an ideal hole‐selective contact. To overcome these issues, antisolvent treatment...
Cryogenic fluids have extensive applications as fuel for launch vehicles in space and research. The physics of cryogenic flows are highly complex due to the sensitive nature phase transformation from liquid bubbly vapor, eventually resulting cavitating at ambient temperature owing very low boiling point fluids, which asserts us classify such under multi-phase flow regime. This work elucidates modeling nitrogen a converging-diverging venturi-like device known venturi, passive control metering...
