Abstract Lead (Pb) halide perovskite solar cells (PSCs) exhibit impressive power conversion efficiencies close to those of their silicon counterparts. However, they suffer from moisture instability and Pb safety concerns. Previous studies have endeavoured address these issues independently, yielding minimal advancements. Here, a general nanoencapsulation platform using natural polyphenols is reported for Pb‐halide PSCs that simultaneously addresses both challenges. The polyphenol‐based...
Abstract Optical inspection has long served as a cornerstone non‐destructive method in semiconductor wafer manufacturing, particularly for surface and defect analysis. However, conventional techniques such dark‐field scattering optics or atomic force microscopy (AFM) face significant limitations, including insufficient resolution the inability to resolve subsurface features. Here, an approach is proposed that integrates strengths of AFM by leveraging van der Waals (vdW) canalization lens...
Abstract Photodetectors based on 2D hetero‐bilayers can overcome the bandgap limitations of individual monolayers and operate at relatively long wavelengths. However, ultra‐low light absorptions within result in extremely weak photoresponsivity. Here, an infrared photodetector MoS 2 /MoTe type‐II hetero‐bilayer is demonstrated to reach a photoresponsivity 0.55 A W −1 1550 nm, well beyond energy band cut‐offs monolayer MoTe , primarily resulted from photogating effect. Raman photoluminescence...
