Enhancing Indoor Photovoltaic Efficiency to 37.6% Through Triple Passivation Reassembly and n‐Type to p‐Type Modulation in Wide Bandgap Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Triple Passivation Treatment (TPT) strategy enables 1.75 eV wide‐bandgap perovskite solar cells (WB‐PSCs) with suppressed halide phase segregation and n‐to‐p type surface transition. The photoluminescence quantum yield increases from 0.5 to 2.1%, indicating reduced non‐radiative losses.

Language-guided Semantic Style Transfer of 3D Indoor Scenes [PDF]

open access: yesarXiv, 2022
We address the new problem of language-guided semantic style transfer of 3D indoor scenes. The input is a 3D indoor scene mesh and several phrases that describe the target scene. Firstly, 3D vertex coordinates are mapped to RGB residues by a multi-layer perceptron. Secondly, colored 3D meshes are differentiablly rendered into 2D images, via a viewpoint
