Summary: Arsenic-containing conjugated polymers, with dithieno[3,2-b:2',3'-d]arsole as a typical monomer unit, have gained significant attention recently. However, the traditional polymer design for improved solubility often involves introducing long alkyl chains, which may lead to steric hindrance and distort the planarity of the polymer chain. To overcome this, a novel monomer with an alkoxyphenyl group substituted on the arsenic atom was developed. These polymers, using benzothiadiazole and benzoxadiazole monomers, exhibited high planarity and solubility, as well as near-infrared emissions.

Summary: Room-temperature sodium-sulfur batteries have high energy density and low cost, but the presence of high-order polysulfides leads to capacity fading and low-order polysulfides have slow reaction kinetics. This study introduces microporous-mesoporous carbon derived from mangosteen peels as cathode materials, which effectively suppresses the shuttling effect of sodium polysulfides, and provides high electrical conductivity and porosity for efficient electron/ion diffusion. The obtained sodium-sulfur battery exhibits high reversible capacity, excellent long-term cycle performance, and outstanding rate performance.

Summary: In this work, 3D amorphous mixed-valence VOx microspheres were in situ grown on alkali-treated carbon cloth (VOx MSs@ACC) as cathodes for AZIBs. Compared to a VOx MSs powder-constructed cathode, VOx MSs@ACC cathodes exhibit higher specific capacity (1.79 mA h cm(-2) at 2.7 A m(-2)) and longer cycling performance over 2500 cycles mainly due to their faster ion transport rates, abundant ion storage sites, and more effective easing of volume expansion. This work sheds light on the design of free-standing vanadium-based cathodes for AZIBs.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
