The mechanisms of a charge injection-induced electrohydrodynamic pump using the lattice Boltzmann method are numerically investigated in this paper. is composed dielectric liquid layer and two substrate layers with embedded electrodes. There three possible flow modes found, which associated generation local convective rolls for different electrode arrangements, namely, one vortices an irrotatio...

Dye sensitized solar cells (DSSCs) employing a dimer porphyrin, which was synthesised with two porphyrin units connected without conjugation, have shown that both porphyrin components can contribute to photocurrent generation, that is, more than 50 % internal quantum efficiency. In addition, the open-circuit voltage (Voc) of the DSSCs was higher than that of DSSCs using monomer porphyrins. In t...

A behavioral model of a second order switchedcapacitor Sigma-Delta modulator is presented. The purpose of this work is the presentation of a behavioral model of a second order switched capacitor ΣΔ modulator considering (Error due to Clock Jitter, Thermal noise Amplifier Noise, Amplifier Slew-Rate, Non linearity of amplifiers, Gain error, Charge Injection, Clock Feedthrough, and Nonlinear on-re...

Analysis of the electrostatics of charge carrier injection into molecular crystals during nonequilibrium electron transfer reactions demonstrates the unique advantage of aqueous or similar electrodes in measuring limiting currents which yield the rate constant of the injection process. At the phase boundary molecular crystal/aqueous electrolyte image forces are negligible due to the slow orient...

Organic-inorganic hybrid systems based on lead halide compounds have recently encountered considerable success as light absorbers in solid-state solar cells. Herein we show how fundamental mechanistic processes in mesoporous oxide films impregnated with CH3NH3PbI3 can be investigated by time resolved techniques. In particular, charge separation reactions such as electron injection into the tita...

the Si-SiO, interface at the moment of injection has a measurable effect on charge trapping and detrapping processes within the oxide. The trapped charge density decreases with increasing p-well bias. The proposed mechanism for this effect is the interaction of hot electrons injected into the conduction band of the SiO, with trapping sites previously formed in the oxide. The effect is significa...
