Abstract Simultaneously harvesting, converting and storing solar energy in a single device represents an ideal technological approach for the next generation of power sources. Herein, we propose consisting integrated carbon-based perovskite cell module capable harvesting (and it into electricity) rechargeable aqueous zinc metal cell. The electrochemical storage utilizes heterostructural Co 2 P-CoP-NiCoO nanometric arrays as cathode anode, respectively, shows capacity retention approximately...
Abstract Exceptional points (EPs) have been extensively explored in mechanical, acoustic, plasmonic, and photonic systems. However, little is known about the role of EPs tailoring dynamic tunability optical devices. A specific type as chiral has recently attracted much attention for controlling flow light building sensors with better responsivity. demonstrated route to via lithographically defined symmetric Mie scatterers on rim resonators not only provided much-needed mechanical stability...
Polycrystalline perovskite films fabricated on flexible and textured substrates often are highly defective, leading to poor performance of devices. Finding substrate-tolerant fabrication strategies is therefore paramount. Herein, this study shows that adding a small amount Cadmium Acetate (CdAc2 ) in the PbI2 precursor solution results nano-hole array improves diffusion organic salts promotes favorable crystal orientation suppresses non-radiative recombination. substrate with ultra-long...
In recent years, organic–inorganic hybrid perovskite (PVK) devices have attracted widespread attention with their high absorption coefficient and low-cost fabrication process. Formamidinium lead iodide (FAPbI3) solar cells (PSCs) been reported to obtain power conversion efficiencies (PCEs) due the narrow bandgap. Zinc oxide (ZnO) has better electrical conductivity transmittance than tin (IV) dioxide (SnO2). However, deprotonation behavior of ZnO limits its use in formamidinium (FA) or...
A heterogeneous seed-assisted FAPbI 3 crystallization facilitated by the 2,4-diaminopyrimidine (DAP) molecule, was employed to promotes highly-crystalline α-FAPbI film, significant increasing efficiency of inverted device 25.29%.
A highly efficient quadruple-junction silicon based thin-film solar cell with a remarkably high open-circuit voltage was demonstrated to inspire functional photoelectrical devices for environmental applications.
A low voltage, high speed, compact silicon Mach-Zehnder Interferometer (MZI) modulator for Binary Phase Shift Keying (BPSK) modulation has been demonstrated. High efficiency, VπLπ equals to 0.45V·cm, was obtained in a 1mm length device owing higher doping concentration and low-loss traveling-wave electrode. 25 Gb/s non-return-to-zero(NRZ)-BPSK with 6Vpp RF driving signal achieved. Driven by very 3Vpp signal, the 10 NRZ-BPSK also realized benefiting from efficiency low-voltage scheme. The...
We report mid-infrared Ge-on-Si waveguide-based PIN diode modulators operating at wavelengths of 3.8 and 8 μm.Fabricated 1-mm-long electro-absorption devices exhibit a modulation depth >35 dB with 7 V forward bias μm, similar Mach-Zehnder modulator has π • L 0.47 cm.Driven by 2.5V pp RF signal, 60 MHz on-off keying was demonstrated.Electro-absorption μm demonstrated preliminarily, the device performance limited large contact separation high resistance.
ABSTRACT The sulfonated polybenzimidazole (sPBI)/sulfonated imidized graphene oxide (SIGO) was evaluated to be a potential candidate for high temperature proton exchange membranes fuel cells (HT‐PEMFCs). Multifunctionalized covalently bonded SIGO is incorporated in sPBI matrix resolve the drawbacks such as low conductivity, poor water uptake, and ion‐exchange capacity (IEC) of polymer, synthesized by direct polycondensation phosphoric acid application membranes. Strong hydrogen bonding among...
Aryl-ether cleavage and benzylic quaternary ammonium (QA) group degradation are promoted by C═O groups in most commercial anion exchange membrane materials. Herein, a novel strategy of converting to the electron-donating C-NH2 linkages conventional poly(arylene ether ketone)s is proposed reductive amination via Leuckart reaction. Density functional theory (DFT) calculations indicate that model compound containing linkage exhibits much higher barrier heights for aryl-ether QA enhancing...
