Anion passivation effect on metal-oxide nano-architecture offers a highly controllable platform for improving charge selectivity and extraction, with direct relevance to their implementation in hybrid solar cells. In current work, we demonstrated the incorporation of fluorine (F) as an anion dopant to address the defect-rich nature of ZnO nanorods (ZNR) and improve the feasibility of its role a...

Graphene is the thinnest two-dimensional (2D) carbon material and has many advantages including high carrier mobilities and conductivity, high optical transparency, excellent mechanical flexibility and chemical stability, which make graphene an ideal material for various optoelectronic devices. The major applications of graphene in photovoltaic devices are for transparent electrodes and charge ...

The recently proposed partition theory (PT) (J. Phys. Chem. A2007, 111, 2229.) is illustrated on a simple one-dimensional model of a heteronuclear diatomic molecule, 1DAB. It is shown that a sharp definition for the charge of molecular fragments emerges from PT and that the ensuing population analysis can be used to study how charge redistributes during dissociation and the implications of that...

This paper presents a study in neural networks for short-term predictions, in the scope of electric load forecasting in the presence of charge transfer scenarios. Charge transfers are humanprovoked transfers of electrical charge from one subnetwork to another, due to a shift in both subnetwork’s needs. This work studied the problem of how to dynamically adapt the model when a situation of charg...

PURPOSE We report the novel use of 3-charge coupled device camera technology to infer tissue oxygenation. The technique can aid surgeons to reliably differentiate vascular structures and noninvasively assess laparoscopic intraoperative changes in renal tissue perfusion during and after warm ischemia. MATERIALS AND METHODS We analyzed select digital video images from 10 laparoscopic partial ne...

The interface of Pt/TiO2 plays an essential role in device engineering and chemical reactions. Here, we report the electrostatic potential distribution a by electron holography. decrease exists at TiO2 vicinity interface, indicating presence negative charge due to transfer from Pt. can be understood difference work functions between Pt TiO2. This study reveals interplay usefulness holography fo...

Charge transport properties of thiophene, thiazole and thiazolothiazole based oligomers have been studied using electronic structure calculations. The charge transport parameters such as charge transfer integral and site energy are calculated through matrix elements of Kohn-Sham Hamiltonian. The reorganization energy for the presence of excess positive and negative charges and rate of charge tr...

The reproducible silylation of titanium oxide (TiO2) with small molecular (dichloromethyl) dimethylchlorosilane (DCS) as the cathode buffer layer was developed to improve electron extraction. Through incorporating the DCS capping layer into polymer solar cells (PSCs), the interfacial coherence of devices could be enhanced, leading to a shift in nanocrystallite size and a smaller internal charge...

In this theoretical study, we focus on a kind of danunarane sapogenins. This molecule optimized in venoussolvent media such as heptao, carbontetrachloride, toluene. tetrahydrofurane, dichloroethane, ethanol, methanol,dimethylsulfoxide and water using the self-consistent reaction field model. This process depends on either thereaction potential function of the solvent or charge transfer operator...
