Summary: This study explores a method to achieve high efficiency and stability in semiconducting lead halide perovskite nanocrystals (PNCs) through a single processing strategy by finding suitable surface ligands. The PNC ink prepared using this method can be used to fabricate both LED and PV devices, with peak electroluminescence external quantum efficiency of 17.00% and power conversion efficiency of 14.92%. It is found that a careful design of the aromatic rings in the ligands is crucial for achieving high performance, ease of processing, and improved phase stability. This research demonstrates the role of ligand design in PNC ink formulations for high-throughput production of optoelectronic devices and paves the way for dual-mode devices with both PV and LED functionalities.

Summary: Cu2SnS3 is a promising thermoelectric material for medium-temperature power generation with low-cost and environmental-benign features. Analog alloying with CuInSe2 is adopted to optimize its electrical resistivity and lattice thermal conductivity, resulting in greatly enhanced power factor and reduced lattice thermal conductivity. A peak ZT value of 1.14 at 773 K is achieved for Cu2SnS3 - 9 mol.% CuInSe2, which is one of the highest among Cu2SnS3-based thermoelectric materials. The study demonstrates that analog alloying with CuInSe2 is an effective route to unleash superior thermoelectric performance of Cu2SnS3.

Summary: Radiative cooling effect can passively reduce the operating temperature of photovoltaic (PV) systems by utilizing the atmospheric window. The emissivity of glass in the atmospheric window can be improved by microstructuring the glass surface, enhancing its radiative cooling capacity. Experimental results show that the temperature difference between glass samples and solar cells ranges from 0.1 to 2.0 degrees Celsius under different meteorological conditions, and there is no correlation between temperature difference and wind speed.

Summary: We have discovered the emergence of photocapacitance in two-dimensional layered nanocrystal assemblies. By applying a lateral bias across interdigitated electrodes, we electrically probe the devices and observe capacitive current-voltage characteristics that are absent in the individual nanocrystals. In addition to a large zero-bias capacitance, the assemblies exhibit a transient negative capacitive behavior with small signal capacitance values ranging from +/- 100 nF. We demonstrate that this system behaves as a damped anharmonic oscillator and show the modulation of capacitive behavior by incident light, making these materials suitable for photocapacitive detector devices.

Summary: Nanospherical composites of SnSe/Fe and SnSe/Ni were synthesized and studied for their application in supercapacitors and photovoltaic material for energy storage devices. The crystal structure of SnSe/Fe and SnSe/Ni NSC was confirmed using XRD, and morphology analysis revealed their spherical to ball-like transformation. The direct energy bandgap values of SnSe, SnSe/ Fe and SnSe/Ni NSC were 2.8 eV, 2.6 eV and 2.1 eV, respectively. SnSe/Ni electrode exhibited the highest specific capacitance and energy density, outperforming SnSe/Ni and pure SnSe electrodes. Moreover, DSSCs based on NiSnSe hybrid counter electrode achieved a higher power conversion efficiency compared to FeSnSe, SnSe, and conventional platinum CEs.

Summary: By integrating UCNPs into different transport layers, device performance was optimized, with short-circuit current density and PCE reaching 20.87 mA/cm(2) and 18.34%, respectively, without sacrificing open-circuit voltage and filling factor. Experimental characterizations confirmed that the enhancement in performance was due to improved visible light absorption rather than infrared.

Summary: Metavanadates MV2O6-delta (M = Zn and Cu) were synthesized using a deep eutectic solvent (DES) as a reaction medium, resulting in the formation of oxygen-deficient materials with reduced band gaps and enhanced sub-band gap photon absorption. The presence of oxygen vacancies introduced by the DES route significantly altered the structural and optical properties of the oxides. Photoelectrochemical measurements confirmed the potential use of these materials as photoanodes for methanol oxidation, with n-type behavior and electron majority charge carriers identified through surface photovoltage spectroscopy.
