While SnF2 is reported as an effective additive for improving the efficiency of lead-free tin-based perovskite solar cells, mechanism still unclear and requires further studies. Upon incorporating into MASnI3, reduces intrinsic carrier density from 1018 to 1012 cm–3 produces a longer diffusion length confirmed by Hall measurements. The femtosecond transient absorption spectroscopy shows that doping enhances hot-phonon bottleneck effect MASnI3. slow cooling process hot carriers may help...
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...
The current research status of perovskite oxides in fabricating energy harvesters and designing new quantum states is reviewed.
The pulsed laser deposition (PLD) technique has been proved to be able grow oxide thin films with high structural quality precisely controlled composition and thickness achieve designed optical electronical properties established in alloyed semiconductors heterostructures. In this Letter, inorganic halide perovskite CsPb(IxClyBr1−x−y)3 epitaxial on (001)-SrTiO3(STO) substrates were grown by PLD. film crystal quality, phase stability, the relationship between substrate characterized a...
Power consumption makes next-generation large-scale photodetection challenging. In this work, the source-gated transistor (SGT) is adopted first as a photodetector, demonstrating expected low power and high performance. The SGT constructed by functional sulfur-rich shelled GeS nanowire (NW) low-function metal, displaying saturated voltage of 0.61 V ± 0.29 an extremely 7.06 pW. When as-constructed NW used maximum value 11.96 nW, which far below that reported phototransistors working in...
High-quality lattice-matched LaNiO3/LaMnO3 superlattices with monolayer terrace structure have been grown on both (111)- and (001)-oriented SrTiO3 substrates by pulsed laser deposition. In contrast to the previously reported experiments, a magnetic exchange bias is observed that reproducibly occurs in thin single layers of 5 7 unit cells, respectively. The theoretically explained charge transfer-induced moments at Ni atoms. Furthermore, magnetization data low temperature suggest two phases...
To regulate the optical and electrical properties of intrinsic methylammonium lead iodide (CH3NH3PbI3) crystals films, we dope them with sodium (Na) by selecting (NaI) as dopant source. The highly conductive p-type sodium-doped CH3NH3PbI3 (MAPbI3: Na) perovskite single thin films are successfully grown inverse temperature crystallization (ITC) method antisolvent spin-coating (ASC) method, respectively. With increase Na+ doping concentration, grain size film increases, surface becomes...
All-inorganic perovskite CsPbX3 nanocrystals (NCs) have made remarkable achievements in optoelectronic applications due to their enhanced stability, low-cost, easy-to-perform synthetic routes, broad emission spectra tunability, and high photoluminescence quantum yields, especially for light emitting diodes (LEDs) solar cells (SCs). In this perspective, the structure properties of NCs are reviewed, recent research progresses LEDs SCs presented. Finally, a brief outlook field is proposed point...
