Summary: Two-dimensional 4H-polytype tin disulfide (SnS2) flakes were synthesized and exfoliated into bilayers using the chemical vapor transport technique and mechanical exfoliation technique, respectively. The exfoliated layers exhibited high on/off ratio and mobility, but low mobility in the 4H-SnS2 FET devices indicated an insulating state. The optical bandgap energies of the 2D SnS2 single-crystal layers were significantly widened in the bilayers and tri-layers, offering potential for downscaled nanoscale semiconducting devices.

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.
