Summary: The typical polyol-based synthesis of silver nanowires using insulating polymer as a surfactant limits direct contact between each nanowire, affecting optoelectronic properties. A simple solvent treatment effectively removes the insulating polymer, leading to decreased sheet resistance and increased transmittance. Transparent film heaters using the treated silver nanowire network rapidly reached 150 degrees C under a bias of 5 V, demonstrating great potential for flexible transparent electrode and film heater applications.

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.

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. 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.
