Abstract Interfacial ligand passivation engineering has recently been recognized as a promising avenue, contributing simultaneously to the optoelectronic characteristics and moisture/operation tolerance of perovskite solar cells. To further achieve win‐win situation both performance stability, an innovative conjugated aniline modifier (3‐phenyl‐2‐propen‐1‐amine; PPEA) is explored moderately tailor organolead halide perovskites films. Here, PPEA presents “quasi‐coplanar” rigid geometrical...
Photovoltaic systems technological development is driven by the request for higher efficiency and safety. These concerns influence also choice of power converter stage. Several topologies have been proposed many them are available commercially. Among them, neutral point clamped (NPC) derived offers high efficiency, low leakage current, EMI. However, one main disadvantage NPC inverter given an unequal distribution losses in semiconductor devices, which leads to temperature that can affect...
Abstract This review discusses the utilization of metal halide perovskite (MHP) materials in X‐ray direct imaging detectors for medical application. Compared to traditional semiconductors, MHP has multiple advantages including high linear attenuation coefficient, low exciton binding energy, long carrier diffusion length, and mobility. These ascendancies allow low‐dose high‐resolution imaging. Apartment from a historical overview develop‐X‐ray their performance indicators, this specifically...
Recent developments in flexible electronics have heightened the need for electrolytes with high safety, ionic conductivity, and electrochemical stability. However, neither conventional organic nor aqueous can meet above requirements simultaneously. Herein, a novel "water-in-deep eutectic solvent" gel (WIDG) electrolyte synergistically controlled by solvation regulation gelation strategies is reported. The water molecules introduced into deep solvent (DES) participate structure of Li+, thus...

Due to the large surface of PV generator, its stray capacity with respect ground reaches values that can be quite high. When no transformer is used in a grid-connected system, common-mode current, which caused by common mode voltage, flow through capacitance between array and ground. It harmful body safety system. In order avoid leakage different inverter topologies generate varying voltages, such as bipolar pulse-width modulation (PWM) full-bridge topology, NPC topology have been proposed....

In this paper, we propose a high-resolution time-frequency rate representation (HR-TFRR) and derive its analytical formula. This formula implies that the HR-TFRR has narrower frequency support than cubic phase function (CPF). Therefore, higher (FR) resolution CPF can distinguish closer components in domain. Due to bilinear transform, suffers cross term when instantaneous functions of are or very close. order suppress term, further smoothed (SHR-TFRR) by introducing an FR window HR-TFRR,...
