The electron transport layer (ETL) plays a critical role in high efficiency perovskite solar cells. In this study, an anodic TiO2 nanotube film was transformed into a TiO2 nanotube network film, which maintained its advantage as an efficient ETL for perovskite solar cells. Compared with the mesoporous TiO2 nanoparticle ETL, the TiO2 nanotube network ETL can increase the efficiency of perovskite...

Various classes of non-quiescent magnetized plasma exhibit anomalous energy and/or momentum diffusivity. In this case, ‘anomalous’ is meant to characterize a transport regime wherein the measured property flux disagrees with classical theory. In most examples anomalous transport is substantially higher than classical expressions predict; it is no different for the Hall accelerator. It has been ...

In this work, we describe a room-temperature, solution-processable organic electron extraction layer (EEL) for high-performance planar heterojunction perovskite solar cells (PHJ PVSCs). This EEL is composed of a bilayered fulleropyrrolidinium iodide (FPI)-polyethyleneimine (PEIE) and PC61BM, which yields a promising power conversion efficiency (PCE) of 15.7% with insignificant hysteresis. We re...

Negative diagonal magneto-conductivity/resistivity is a spectacular- and thought provoking-property of driven, far-from-equilibrium, low dimensional electronic systems. The physical response of this exotic electronic state is not yet fully understood since it is rarely encountered in experiment. The microwave-radiation-induced zero-resistance state in the high mobility GaAs/AlGaAs 2D electron s...

Active transport of salts by higher plant tissues has been shown to depend on aerobic respiration (13). Although active transport under anaerobic condlitions has been reported for a number of animal tissues (19, 32) and for yeast (5, 6), transport in higher plants has been taken to be 02 (lependent. During aerobic respiration, electrons are transferred fronm respiratory intermediates to 02 via ...

Active transport of proline remained unaffected in phospholipase A-treated electron transport particles from Mycobocierium phlei. However, the steady state level of proline was reduced 50 to 60% in phospholipase A-treated depleted electron transport particles that were devoid of membrane-bound coupling factor-latent ATPase activity. The decrease in the uptake of proline in the phospholipase A-t...

Electron thermal transport in DIII-D H-mode tokamak plasmas ͓J. L. Luxon, Nucl. Fusion 42, 614 ͑2002͔͒ is investigated by comparing predictive simulation results for the evolution of electron temperature profiles with experimental data. The comparison includes the entire profile from the magnetic axis to the bottom of the pedestal. In the simulations, carried out using the automated system for tran...
