Summary: Flexible CZTSSe solar cells, which have abundant earth elements, high stability, and wide application prospects, have gained significant attention. However, the high toxicity of the Cd in the buffer layers poses environmental problems. In this study, a Cd-free flexible CZTSSe/ZnO solar cell was developed, and the influence of ZnO films on device performances was investigated. The removal of the CdS layer enhanced the light absorption capacity of flexible CZTSSe solar cells. The optimized thickness of the ZnO buffer layers and the appropriate annealing temperature of the CZTSSe/ZnO were found to be 100 nm and 200 C-?. Ultimately, the optimized device achieved an efficiency of 5.0%, which is the highest for flexible CZTSSe/ZnO solar cells. Systematic characterizations showed that the optimized flexible CZTSSe/ZnO solar cells exhibited quality heterojunction, low defect density, and better charge transfer capability. This work provides a new strategy for the development of environmentally friendly and low-cost flexible CZTSSe solar cells.

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.
