The simple and effective strategy encompassing nanoscale morphological engineering, surface modification, and doping improves the performance of LTO-based anode materials for high energy density and high power LIBs applied in large scale energy storage.
We report on compositional and morphological engineering of mixed methylammonium (MA) and formamidinium (FA) lead triiodide (MA1−xFAxPbI3) perovskite absorber layers to produce highly efficient planar and flexible perovskite solar cells (PVSCs) with reduced hysteresis.
Herein, we demonstrate that nano-sized morphological engineering is a facile and effective strategy to improve the electrochemical performance of the manganese dioxide (MnO2) for LIBs.
With optimal compositional and morphological engineering, the average power conversion efficiency (PCE) improves from 15.74±0.74% for pure MAPbI3 PVSCs to 19.40±0.32% for MA0.7FA0.3PbI3 PVSCs with 3% Pb SCN 2 additive, exhibiting a high reproducibility and small hysteretic behavior.
Furthermore, the compositional and morphological engineering allowed the fabrication of efficient flexible PVSCs on indium-doped SnO2 (ITO)/polyethylene terephthalate (PET) substrates, with the best PCE of 17.96 16.100)% with a VOC of 1.076 (1.020) V, a JSC of 22.23 22.233) mA/cm2 and a FF of 75.10 71.022)% when measured under reverse (forward) voltage scan.
Morphological engineering include both the different NW facets and nanostructures on them.
However, consequently from this simplistic simulation, much drastic variations of R s and R sh recom are correlated with the morphological engineering.
Here, we achieve morphological engineering in the form of novel quantum dots (QDs), 'square' quantum rings (QRs), 'rectangular' QRs, 3D QRs, crescent-shaped QRs, and nano-antidots.
A variety of tests were conducted on pond ash samples collected from Panki and Panipat thermal power station to study the physical, chemical, mineralogical, morphological and engineering behavior.
The high controllability of dip-coating technique and the obtained correlation between dip-coating process engineering and the morphological feature of the TiO2 nanoparticle-modified FTO electrodes as well as the optical performance of the fabricated devices provide valuable guidance for rational design and performance optimization of the electrochromic device with required optical properties.
