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, Masaud Hassan S Almalki, Aditya Mishra, Felix Thomas Eickemeyer, Michael Allan Hope, Anurag Krishna, Zhiwen Zhou, Chenxu Zhao

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, Hongwei Li, Chenxu Zhao, 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, Yu-Ting Huang, Chenxu Zhao

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 ...

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 ...

Ionic-liquid-like copolymer stabilized nanocatalysts in ionic liquids: II. Rhodium-catalyzed hydrogenation of arenes

Paul Joseph Dyson, Ning Yan, Chenxu Zhao

Rhodium nanoparticles stabilized by the ionic-liq.-like copolymer N-Vinyl-2-pyrrolidone-1-vinyl-3-butylimidazolium chloride-1-vinyl-3-ethylimidazolium bromide copolymer were used to catalyze the hydrogenation of benzene and other arenes in ILs. The nanopar ...
