Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors
Advanced Functional Materials, EarlyView.Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...

A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance
Advanced Functional Materials, EarlyView.The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device
