We present a novel haptic rendering framework that translates the performer's motions into wearable vibrotactile feedback for an immersive virtual reality (VR) performance experience. Here, we employ pipeline extracts meaningful parameters including intensity and location. compute these from upper-body movements which play significant role in dance performance. Therefore, customize vest sleeves to support on frontal back parts of torso shoulders as well. To capture essential VR performance,...
Amorphous Zn2SnO4 (am-ZTO) films with extreme surface uniformity, high electron mobility, and fewer charge traps were successfully developed by controlling the concentrations of 2-methoxyethanol solutions containing 2:1 stoichiometric ratio Zn to Sn. For first time, we demonstrate that solution-processed am-ZTO thin are highly efficient as an electron-selective layer (ESL) for mixed perovskite solar cells (PSCs). When ESLs combined bandgap-tuned FAMAPbI3 perovskites, a champion efficiency...
The effect of low‐dose gamma‐ray irradiation on an amorphous SnO 2 electron‐selective layer (ESL) was investigated in this study. Further, its impact the photovoltaic (PV) performance planar perovskite solar cells (PSCs) based MAPbI 3 and CsFAMAPbIBr absorber layers has been evaluated for first time. properties were substantially modified by regulatory exemption radioactive sources (Co‐60). Gamma‐ray promoted formation large grains creating a hydrophilic surface via generation ─OH film...

Zinc oxide (ZnO) is a wide-band-gap semiconductor that promising for use as transparent conductive film. To date, to improve their optoelectrical properties, pristine ZnO films have been doped with metals using various techniques. In this study, nanostructured Cu-ZnO thin were synthesized modified two-step radio frequency magnetron sputtering technique separate and metallic Cu targets. Controlling the timing of Cu/ZnO co-sputtering ZnO-only steps afforded significant change in resulting...
Although the Bi2S3 QDs have an ideal bandgap for efficient light absorbers, sensitised solar cells generally indicate low photovoltaic properties owing to active photocorrosion of QDs. Herein, we report enhancement using co-sensitisation with CdS By homogeneous covering as well effective blocking and recombination, CdS/Bi2S3 co-sensitised showed three-fold increase in efficiency.
In this study, both one-dimensional (1D) and three-dimensional (3D) methylammonium lead iodide (MAPbI3) were successfully synthesized from the same starting precursor solution using a one-step in situ spin-coating process assisted by antisolvent washing with different ethereal solvents. Antisolvent diethyl ether (DE) induced isotropic growth, resulting dense 3D MAPbI3 films. However, dibutyl (DB) having complementary properties promoted 1D directional growth to avoid steric hindrance...
Abstract In this work, TiO 2 nanoparticles and submicron-sized granules were synthesized by a hydrothermal method spray pyrolysis, respectively. Submicron-sized dispersed into the nano-sized layer to improve light conversion efficiency. Granules showed better scattering, but lower in terms of dye-loading quantity recombination resistance compared with nanoparticles. Consequently, had higher cell efficiency than granulized layer. When nanoparticle layer, scattering was enhanced without loss...
Perovskite quantum dots (PEQDs) are next-generation dot materials that have attracted attention in various areas such as display, radiation scintillator, and photodetector. However, PEQD defects occur for reasons hinder the commercialization of PEQDs. Herein, we reported a new strategy hybrid ligand comprising 1-octanethiol (OT) octylammonium bromide can passivate effectively reduce Stokes shift. First, increase OT concentration ligands leads to an size decrease Second, stabilize solution by...
