Summary: We demonstrated a bilayer electron transport layer (ETL) architecture for high-performance perovskite solar cells (PSCs), with a chemical-bath-deposition-based titanium dioxide (TiO2) thin layer and a spin-coating-based tin oxide (SnO2) thin layer. The bilayer ETL not only produces larger grain size of PSCs, but also provides higher current density and reduced hysteresis. Compared to mono-ETL PCSs with an efficiency of 16.16%, the bilayer ETL device features a higher efficiency of 17.64%.

Summary: The perovskite inorganic-organic solar cells utilize a sandwich structure consisting of mesostructured TiO2, CH3NH3PbI3, and Spiro-OMeTAD, with the crystallinity, structural morphology, and thickness of the TiO2 layer playing a crucial role in improving device performance. The randomly distributed one dimensional (1D) TiO2 nanowires (TNWs) provide better light trapping and active filling compared to bulk TiO2, leading to high open circuit voltage and conversion efficiency in solid-state photovoltaic devices. Finite-difference time-domain (FDTD) analysis shows improved light trapping capabilities at the interface of TNWs/CH3NH3PbI3 compared to bulk TiO2.

Summary: The high performance of perovskite solar cells was achieved by using an electron transport layer (ETL) and hole transport layer. A film ETL (mesoporous (meso)-TiO2/carbon dot) was found to enhance the efficiency of the perovskite solar cells. Coating carbon dot on a meso-TiO2 ETL was shown to reduce pin-holes in the perovskite film layer, resulting in a 3% increase in the average power conversion efficiency (PCE). The absorption properties of the meso-TiO2/carbon dot ETL were superior, leading to higher power conversion efficiency compared to meso-TiO2 ETL. The deposition of carbon dot on meso-TiO2 ETL reduced carrier recombination and perovskite film cracks, thereby improving device performance.

Summary: The defects formed by halide ion escape and the wettability of the perovskite absorber are important factors limiting the performance of perovskite solar cells (PSCs). In this study, a series of ionic organic modulators containing halide anions were designed to prevent defect formation and improve the surface tension of the perovskite absorber. It was found that the modulator containing Br anions was the most effective in reducing charge recombination and promoting carrier transfer. Additionally, this modulator improved the hydrophobicity of the perovskite surface. As a result, the efficiency of PSCs using the Br-containing modulator increased to 23.32% from the control device's efficiency of 21.08%. The unencapsulated PSCs with the modulator also showed excellent stability, retaining 75.42% of their initial efficiency after 28 days of storage in air with about 35% humidity, compared to the control device's 44.49% retention. The research demonstrates the importance of halide ions in defect prevention and surface tension improvement of perovskite absorber, and highlights the potential of ionic organic modulators for enhancing PSC performance.

Summary: Nd-doped TiO2 is used as an electron-transport layer (ETL) in perovskite solar cells (PSCs) to enhance the power conversion efficiency (PCE). The doping effect of Nd reduces trap states and improves electron mobility and conductivity of TiO2, leading to a well-matched energy level with the perovskite layer. The CsPbBr3 PSCs based on Nd-TiO2 ETL achieve a champion PCE of 10.06% with improved charge extraction and reduced charge recombination, surpassing the 6.57% efficiency of the reference cell. Moreover, the unencapsulated device exhibits enhanced stability with over 90% and 80% retention of the original efficiency after aging in high humidity and under intense illumination, respectively.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.
