Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Modification of Metal Microelectrodes with Vertical Graphene Structure for Enhanced Electrochemical Detection of Dopamine

open access: yesAdvanced Materials Interfaces, EarlyView.
In this article, vertical graphene‐modified microelectrodes (VGMEs) are fabricated by modifying vertical graphene on different types of metal microelectrodes (Au, Ti, Ag, and W) for enhanced electrochemical detection of DA. Moreover, the sensing performance on dopamine concentrations is explored with different electrochemical methods, including EIS, CV,

Structure Identification of CO Monolayer on Ag(111) Using Atomic Force Microscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Physisorption systems of CO molecules on metal surfaces have long been studied. Nondestructive analysis of weakly adsorbed systems on surfaces still remains a challenging task. In this study, the structure of the CO monolayer is successfully determined by directly visualizing individual CO molecules using atomic force microscopy (AFM).
