Buried SnI2 Induces Gradient Heterojunctions in Sn–Pb Perovskite Solar Cells

Chenxu Zhao

Tin–lead (Sn–Pb) mixed perovskite solar cells (PSCs) offer the potential for higher power conversion efficiency (PCE) than their pure lead counterparts. However, the lack of a well-defined Sn/Pb compositional profile results in disordered internal electric ...

Stabilization of highly efficient perovskite solar cells with a tailored supramolecular interface

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Felix Thomas Eickemeyer, Chenxu Zhao, Michael Allan Hope, Aditya Mishra, Masaud Hassan S Almalki, Anurag Krishna, Zhiwen Zhou

The presence of defects at the interface between the perovskite film and the carrier transport layer poses significant challenges to the performance and stability of perovskite solar cells (PSCs). Addressing this issue, we introduce a dual host-guest (DHG) ...

Progressive Correspondence Pruning by Consensus Learning

Mathieu Salzmann, Chenxu Zhao, Hongwei Li, Feng Zhu, Rui Zhao

Correspondence pruning aims to correctly remove false matches (outliers) from an initial set of putative correspondences. The pruning process is challenging since putative matches are typically extremely unbalanced, largely dominated by outliers, and the r ...

Evaluation of a Ruthenium Oxyquinolate Architecture for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Chenxu Zhao, Yu-Ting Huang

Synthesis of the Ru(dcbpy)(2)(OQN) complex is reported in which dcbpy and OQN(-) are the bidentate 4,4'-dicarboxy-2,2'-bipyridyl and 8-oxyquinolate ligands, respectively. Spectroscopic, electrochemical, and theoretical analyses are indicative of exten ...

The MicroArray Quality Control (MAQC)-II study of common practices for the development and validation of microarray-based predictive models

Darlene Goldstein, Chenxu Zhao, Mauro Delorenzi, Li Zhang, Vlad Popovici, Jun Luo, Wen Luo, Wei Wang, Ying Liu, Jonathan Koh Boon Han

Gene expression data from microarrays are being applied to predict preclinical and clinical endpoints, but the reliability of these predictions has not been established. In the MAQC-II project, 36 independent teams analyzed six microarray data sets to gene ...

Aqueous-phase biphasic dehydroaromatization of bio-derived limonene into p-cymene by soluble Pd nanocluster catalysts

Paul Joseph Dyson, Weijia Gan, Chenxu Zhao

A biphasic approach to the dehydroaromatization of bioderived limonene into water-insol. p-cymene using sol. Pd nanoparticle catalysts in an aq. phase (³150 °C, 2 bar H2) was successfully achieved with a conversion of 93% and a selectivity of 82%. The Pd n ...

Selective degradation of wood lignin over noble-metal catalysts in a two-step process

Paul Joseph Dyson, Ning Yan, Chenxu Zhao, Cheng Wang

Direct conversion of lignin into alkanes and methanol was carried out in a two-step process (hydrogenolysis and hydrogenation) involving initial treatment of white birch wood sawdust with H2 in dioxane/water/phosphoric acid using carbon supported Ru, Pd, R ...
