A Chemical-Pressure-Induced Phase Transition Controlled by Lone Electron Pair Activity
American Chemical Society (2022-10-17)The chemical pressure approach offers a new paradigm for property control in functional materials. In this work, we disclose a correlation between the β → α pressure-induced phase transition in SnMoO4 and the substitution ... -
Are the Accompanying Cations of Doping Anions Influential in Conducting Organic Polymers? The Case of the Popular PEDOT
Wiley (2019-11-13)Conducting organic polymers (COPs) are made of a conjugated polymer backbone supporting a certain degree of oxidation. These positive charges are compensated by the doping anions that are introduced into the polymer synthesis ... -
Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering

High photocatalytic activity of Ag/Ag3PO4:W heterostructure formed by femtosecond laser irradiation
Sao Paulo State University. Institute of Chemistry (2022-04-11)In this work, the W-doped Ag3PO4 was prepared by the chemical coprecipitation method and irradiated with a femtosecond laser (FL). The successful formation of the Ag/Ag3PO4:W heterostructure was confirmed by XRD analysis. ... -
Imidazolium Iodide-Doped PEDOT Nanofibers as Conductive Catalysts for Highly Efficient Solid-State Dye-Sensitized Solar Cells Employing Polymer Electrolyte
American Chemical Society (2017)The electrical conductivity and catalytic activity of nanofibrous poly(3,4-ethylenedioxythiophene)s (PEDOT NFs) was improved by redoping with dimethyl imidazolium iodide (DMII) as a charge transfer facilitator. Addition ... -
Interfacial and Bulk Operation of Polymeric Solar Cells by Optoelectronics and Structural Techniques
Universitat Jaume I (2014-07-15)This Ph.D. Thesis focuses on the investigation of organic photovoltaic (OPV) technology, especially in aspects of experimental device processing, and optoelectronic and electrical characterization on OPV devices to be ... -
Potassium ions as a kinetic controller in ionic double layers for hysteresis-free perovskite solar cells
Royal Society of Chemistry (2019-07-22)Since ion migration and interaction with external contacts has been regarded as one of the origins for photocurrent density (J)–voltage (V) hysteresis and phase segregation in perovskite solar cells (PSCs) under operational ... -
Triumphing over Charge Transfer Limitations of PEDOT Nanofiber Reduction Catalyst by 1,2-Ethanedithiol Doping for Quantum Dot Solar Cells
American Chemical Society (2017)Charge transfer between a conducting polymer-based counter electrode (CE) and a polysulfide (S2–/Sn2–) electrolyte mediator is a key limitation to improvements of solar energy conversion efficiency (ECE) in quantum-dot-sensitized ... -
Unprecedented solar water splitting of dendritic nanostructured Bi2O3 films by combined oxygen vacancy formation and Na2MoO4 doping
Elsevier (2021-05-27)We demonstrate the synergetic effect of Na2MoO4-doping and vacuum-annealing on dendritic nanostructured bismuth oxide (Bi2O3) thin films prepared by electrodeposition for visible-light-assisted photoelectrochemical (PEC) ... -
Untargeted Metabolomics in Doping Control: Detection of New Markers of Testosterone Misuse by Ultrahigh Performance Liquid Chromatography Coupled to High-Resolution Mass Spectrometry
American Chemical Society (2015)The use of untargeted metabolomics for the discovery of markers is a promising and virtually unexplored tool in the doping control field. Hybrid quadrupole time-of- flight (QTOF) and hybrid quadrupole Orbitrap (Q ...
