Organic Bulk‐Heterojunction‐Integrated Flexible Perovskite Photodetection Arrays for High‐Speed Broadband Optical Communication

open access: yesAdvanced Science, EarlyView.
A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.

A Closed‐Loop Hybrid Discovery System of Type I Photosensitizers for Hypoxic Tumor Therapy

open access: yesAdvanced Science, EarlyView.
The work developed a closed‐loop hybrid discovery system to rationally design and predict high‐performance Type I PSs for hypoxic tumor therapy. 664 Potential candidates are identified from a dataset through a support vector machine (SVM) classification model, and two candidates are experimentally verified as Type I PSs, which highlighted the potential

Recent progress on high-pressure and high-temperature studies of fullerenes and related materials

open access: yesMatter and Radiation at Extremes, 2019
Polymerization of fullerenes is an interesting topic that has been studied for almost three decades. A rich polymeric phase diagram of C60 has been drawn under a variety of pressure P and temperature T conditions.

Hydrogen‐Bonding Networks Enabled by Trace Water for Morphological Design in Ternary Organic Solar Cells

open access: yesAdvanced Science, EarlyView.
Trace water transforms from an impurity to a design handle for ternary organic solar cells. During solvent evaporation, minimal amounts organize transient hydrogen‐bonding networks that steer component migration and set the morphology. The mechanism enables reproducible morphology locking and identifies a practical co‐solvent threshold near H2O:CF = 0 ...

Mapping structure-property relationships in fullerene systems: a computational study from C20 to C60

open access: yesnpj Computational Materials
Fullerenes, as characteristic carbon nanomaterials, offer significant potential for diverse applications due to their structural diversity and tunable properties. Numerous isomers can exist for a specific fullerene size, yet a comprehensive understanding

Defect Dynamics and Solution‐Processed Interconnects in Perovskite‐Organic Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
In this study, we identify the underlying cause of efficiency losses in WBG perovskites, which is ascribed to the presence of mobile defects distributed at surface regions. We further employ effective passivation agent with functional chemical groups to facilitate the healing of the mobile defects, thereby enhancing the VOC to 1.35 V and champion ...

Enhanced Bandgap Flexibility in Perovskite‐Silicon Tandem Solar Cells via Three‐Terminal Architecture

open access: yesAdvanced Science, EarlyView.
Three‐terminal (3T) perovskite/silicon tandem solar cells overcome the current‐matching constraints of 2T designs. Using an IBC POLO silicon bottom cell, we demonstrate a 30.1% PCE, with performance largely decoupled from perovskite bandgap and enhanced resilience under realistic, time‐dependent solar spectra.
