Improvements in the light-harvesting capacity and carrier extraction are both significant to improve photovoltaic performance of perovskite solar cells (PSCs). It has been proved that local surface plasmon resonance (LSPR) based on metallic nanostructures is practical for capturing light enhance harvesting. Motivated by this, a special shaped Au nanoparticle, e.g., nanooctahedrons (Au NOs), with broadband LSPR peak suitable size controlled synthesized applied PSCs device. The power...
A photoluminescence emission band at 830 nm has been detected in single heterojunction quantum well structures (modulation-doped structures) the range of 250–400 K. This is observed neither without a two-dimensional electron gas (2DEG), nor n+ AlGaAs and GaAs. The intensity increases as mobility samples with 2DEG shows excitonic behavior its variation incident laser excitation intensity. was grown by both molecular beam epitaxy organometallic vapor phase epitaxy. effect may be useful rough...
CsPbX3 perovskite nanocrystals (NCs) have attracted much attention from researchers because of their excellent photoelectric properties like high quantum yield, large absorption cross section, and simple preparation process. The addition ligands in the synthesis process has a significant effect on microstructure photophysical solution-processed NCs, which needs further extensive studies. In this Letter, effects ligand electronegativity size photoluminescence (PL) CsPbBr3 NCs were reported....
Double perovskites without lead element have attracted great attention in recent years. Further increasing the photoluminescence quantum yield of lead-free double is necessary for their potential applications. In this work, Na+ doped Cs2SnI6 nanocrystals were synthesized by hot injection method. It was displayed that all NCs uniform hexagonal shape with good crystallization. Energy dispersing spectroscopy and X-ray photoelectron proves ions lattice perovskite structure. The intensity...
Large scale ordered Au nanoarrays are fabricated by nanosphere lithography technique. The photoluminescence improvement of CsPbBr3-xIx nanocrystals more than three times is realized in the nanocrystal/Au nanoarray/Si structure. Time-resolved decay curves indicate that lifetime decreased introducing nanoarrays, which results a increasing radiation recombination rate. reflection spectra with two major valleys (the dip curve) located at ∼325 nm and 545 structure, illustrates plasmonic resonance...
Abstract Perovskite light‐emitting devices (PeLEDs) have emerged as a highly promising contender for the next generation of lighting and display technologies. During nucleation crystallization process, numerous defects are commonly formed on surface grain boundaries result ionic characteristics perovskite, especially in an air environment. These ultimately contribute to deterioration photoelectron properties. In this study, CsPbI 3 nanocrystals (NCs) solution is introduced into ethyl acetate...
Abstract High-performance air-processed perovskite light-emitting devices (PeLEDs) combined with Si materials are currently an opportunity because of the potential applications in multiple function integration. Here, a high-efficient Si/perovskite heterojunction near infrared device have been fabricated by controlling quasi-two-dimensional (quasi-2D) phases via introduction 4-fluorobenzylamine hydroiodide (FPMAI) while whole fabrication process is simple and under ambient air. It was found...
