Summary: This study develops a dual-interface engineering approach to improve the performance of all-inorganic wide-bandgap CsPbI2Br-based front sub-cells in perovskite/organic tandem solar cells (POTSCs). By mitigating the defects and carrier recombination induced by interface defects and perovskite grain boundaries, the CsPbI2Br-based front sub-cells achieve a high power conversion efficiency (PCE) of 17.0% and open-circuit voltage (V-OC) of 1.347 V. Furthermore, by integrating these dual-interface engineered front sub-cells with narrow-bandgap PM6:CH1007-based rear sub-cells, a record PCE of 23.21% is obtained for the POTSCs.

Summary: Metal halide perovskite/silicon tandem solar cells show improved stability under reverse-bias conditions compared to perovskite single-junction devices. The low reverse-bias diode current in the silicon subcell protects the perovskite subcell from degradation.

Summary: Research has found that current matching can be increased for perovskite silicon tandem solar cells by adding a perovskite silicon heterojunction bottom solar cell on top of a planar front/rear side-textured silicon heterojunction bottom solar cell. Optical simulation and planning were used to determine measures for improving the device and maximizing the tandem current density. Variations in the perovskite bandgap and thickness were investigated to achieve current matching between the two subcells. Analysis was also done on limitations such as nonradiative recombination at the perovskite's interfaces. Replacing the hole transport layer PTAA with 2PACz resulted in an increase in the overall certified power conversion efficiency.

Summary: This paper proposes a novel p-type/ultra-thin metal/n-doped electron injection layer (EIL) to significantly enhance the electron injection of inverted bottom organic light-emitting diodes (IBOLEDs). The IBOLEDs based on this EIL show extremely low voltage, high power efficiency, and enhanced device stability. Experimental characterization and simulation reveal that the low work function and self-doping effect of aluminum (Al) increase the electron density and reduce the interfacial energy barrier, while the better film-forming properties of Al decrease the film roughness and improve device stability.

It was found that 1.5 mg HNO2-N/L FNA could virtually abolish N2O emission from the partial-nitritation (PN) sludge, while 45 mg NH3-N/L FA and 0.015 mg HNO2-N/L FNA successfully mitigated N2O production from the full-nitrification (FN) sludge. FA treatment was more economically appealing.

Summary: This study investigated the effects of different dosages, polymer types, and branching extents of microplastics on antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in anaerobic sludge digestion. The results showed that microplastics led to an increase in the relative abundance of ARGs in the sludge, and the dosage and polymer type played a role in this effect. Mechanism studies revealed that a specific polymer (LDPE) selectively enriched potential ARB and ARGs in the surface biofilm, promoting vertical and horizontal gene transfer. Therefore, microplastics can concurrently promote the vertical and horizontal transfer of ARGs in anaerobic sludge digestion.

Summary: The limited mass transfer of CO2 in water hinders the efficiency of CO2 reduction reaction (CO2RR) due to intense competition with the hydrogen evolution reaction (HER). To overcome this challenge, researchers decorated the photocatalyst surface with a hydrophobic carbonaceous cocatalyst to construct a three-phase interface. The decorated photocatalyst exhibited significantly improved CO2-to-CH4 activity and elevated CO2RR selectivity. Molecular dynamics simulations revealed that the hydrophobic microenvironment prevented hydrogen bond formation on the carbonaceous cocatalyst surface. Overall, this study provides a general method to alleviate the CO2 mass transfer limit for accelerated CO2RR in water.

Summary: This study proposes a novel and green strategy, percarbonate-strengthened ferrate pretreatment, to enhance the synthesis of short-chain fatty acids (SCFAs) from sewage sludge. The combination of percarbonate and ferrate showed obvious synergistic effects on SCFAs accumulation and sludge reduction. Mechanism explorations demonstrated that the combination enhanced sludge solubilization, substrate biodegradability, and altered the physiochemical properties of sludge to favor organics fermentation. Further investigations revealed that the combination improved key enzyme activities associated with hydrolysis and SCFAs formation, while inhibiting SCFAs consumption. The combination also altered microbial structures and compositions, leading to the enrichment of key microbes that facilitate SCFAs accumulation.
