Control of dark current in photoelectrochemical (TiO₂/I⁻–I₃⁻) and dye-sensitized solar cells

The ruthenium complex bis-tetrabutylammonium cis-dithiocyanato-N,N9-bis-2,29-bipyridine-4-carboxylic acid, 49-carboxylate ruthenium(II), N-719, was found to block the dark current of dye sensitized solar cells (DSC), based on mesoporous TiO2 films deposited on a F-doped tin oxide electrode and the effect was compared to surface treatment by TiCl4 and the introduction of a compact TiO2 blocking ...

Color Control and White Light Generation of Upconversion Luminescence by Operating Dopant Concentrations and Pump Densities in Yb³⁺, Er³⁺, and Tm³⁺ Tri-Doped Lu₂O₃ Nanocrystals

A Crossed Beam and ab Initio Investigation on the Formation of Boronyldiacetylene (HCCCC¹¹BO; <italic>X</italic>¹⁺) via the Reaction of the Boron Monoxide Radical (¹¹BO; <italic>X</italic>²⁺) with Diacetylene (C₄H₂; <italic>X</italic>¹_g⁺)

The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...

Scanning Electrochemical Microscopy Study of Ion Annihilation Electrogenerated Chemiluminescence of Rubrene and [Ru(bpy)₃]²⁺

Scanning electrochemical microscopy (SECM) was used for the study of electrogenerated chemiluminescence (ECL) in the radical annihilation mode. The concurrent steady-state generation of radical ions in the microgap formed between a SECM probe and a transparent microsubstrate provides a distancedependent ECL signal that can provide information about the kinetics, stability, and mechanism of the ...

Mesoporous Fe₂O₃–CdS Heterostructures for Real-Time Photoelectrochemical Dynamic Probing of Cu²⁺

A three-dimensional (3D) mesoporous Fe2O3−CdS nanopyramid heterostructure is developed for solar-driven, realtime, and selective photoelectrochemical sensing of Cu in the living cells. Fabrication of the mesoporous Fe2O3 nanopyramids is realized by an interfacial aligned growth and self-assembly process, based on the van der drift model and subsequent selective in situ growth of CdS nanocrystal...
