AbstractAs global urbanization rapidly progresses, the dramatic increase in urban population and the number of motor vehicles has intensified traffic safety issues, especially under adverse weather conditions such as heavy fog. These conditions significantly diminish vehicles’ environmental perception capabilities and drivers’ visibility, while the effect of light scattering further increases the risk of traffic accidents, drawing extensive attention in the field of public safety.

3. Experimental Result Analysis 3.1. Joint Failure PhenomenonDuring the loading process of the joint, when the load cannot be further applied and the specimen undergoes significant deformation, it can be considered that the joint has been damaged, and the test stops loading. The load at this point is the maximum load-bearing capacity of the joint, which can also be represented as the critical value.

AbstractKesterite Cu2ZnSn(S, Se)4 (CZTSSe) solar cells are highly promising low-cost thin-film photovoltaics. However, the efficiency of these solar cells is challenged by severe charge losses and complex defects. Here we reveal through a data-driven correlation analysis that the dominant deep defect in CZTSSe exhibits a donor character.

AbstractCharge loss at grain boundaries of kesterite Cu2ZnSn(S, Se)4 polycrystalline absorbers is an important cause limiting the performance of this emerging thin-film solar cell. Herein, we report a Pd element assisted reaction strategy to suppress atomic vacancy defects in GB regions.
