We analyze the performance for reverse-link synchronous DS-CDMA system in a frequency-selective Rayleigh fading channel with an imperfect power control scheme. The performance degradation due to power control error (PCE), which is approximated by a log-normally distributed random variable, is estimated as a function of the standard deviation of the PCE. In addition, we investigate the impacts o...

Abstract A boron subphthalocyanine molecule has been employed as a novel electron donor in organic solar cells (OPVs), and optimized terms of composition device structure small cells. It is demonstrated that the power conversion efficiency (PCE) devices obtained by solution-processing bulk heterojunction could be improved one order magnitude changing fabrication method to vacuum deposition, whi...

Inclined Fluorine Sputtering Processes In article 2301033, Sang-Jin Lee, Jin Young Kim, and co-workers, report a method for improving short-circuit current density (JSC) power conversion efficiency (PCE) of perovskite solar cells (PSCs) by applying an antireflection coating fluorine harnessing the F doping effect on electron transport layer using inclined sputtering process. Consequently, JSC (...

A novel photoanode architecture with plasmonic silver (Ag) nanostructures embedded in titania (TiO2), which served as the wide band gap semiconducting support and CdS quantum dots (QDs), as light absorbers, is presented. Ag nanostructures were prepared by a polyol method and are comprised of clumps of nanorods, 15-35 nm wide, interspersed with globular nanoparticles and they were characterized ...

Perovskite solar cells (PSCs) have attracted tremendous attentions due to its high performance and rapid efficiency promotion. Compact layer plays a crucial role in transferring electrons and blocking charge recombination between the perovskite layer and fluorine-doped tin oxide (FTO) in PSCs. In this study, compact TiO2 layers were synthesized by spin-coating method with three different titani...

We demonstrate high-performance perovskite solar cells with excellent electron transport properties using a one-dimensional (1D) electron transport layer (ETL). The 1D array-based ETL is comprised of 1D SnO2 nanowires (NWs) array grown on a F:SnO2 transparent conducting oxide substrate and rutile TiO2 nanoshells epitaxially grown on the surface of the 1D SnO2 NWs. The optimized devices show mor...

Forming light-transmitting structures on c-Si photovoltaics to transmit visible light without wavelength dependency is a promising strategy realize neutral-color transparent (c-Si TPVs). However, dry etching, which used form structure c-Si, inevitably causes nanoscale surface damages such as scallops and plasma-induced damage in c-Si. This aggravates carrier recombination, decreases power conve...

A D-π-A dye (KM-1) incorporating cyano-benzoic acid as a new acceptor/anchoring group has been synthesized for dye-sensitized solar cells (DSCs) with a high molar extinction coefficient of 66,700 M(-1) cm(-1) at 437 nm. Theoretical calculations show that the hydrogen bond between -CN and surface hydroxyl leads to the most stable configuration on the surface of TiO(2). In addition, the adsorptio...

We demonstrate that incorporation of octadecyltrimethoxysilane (OTMS)-functionalized, spectrally tuned, gold/silica (Au/SiO2) core/shell nanospheres and nanorods into the active layer of an organic photovoltaic (OPV) device led to an increase in photoconversion efficiency (PCE). A silica shell layer was added onto Au core nanospheres and nanorods in order to provide an electrically insulating s...
