Bio‐Derived Natural Materials Based Triboelectric Devices for Self‐Powered Ubiquitous Wearable and Implantable Intelligent Devices

“…Spray-coating atomizes ink and coating the atomized droplets on the surface, both flat and curved ones, of an object at large scale with a spray gun. [298][299][300] Polymer, [298,[301][302][303][304] e.g., PMMA, N-Methyl-2-pyrrolidone (NMP), metallo-supramolecular polymers (MSP, e.g., Fe(II) and Ru(II) based MSPs), and conductive materials, [305][306][307][308][309] e.g., CNTs, silver nanowires (AgNWs), graphene etc. are common materials that can be fabricated into functional films through spray coating.…”

“…Spray-coating has been widely used for coating transparent conductive films in the touch panel, solar cells, etc. [301][302][303][305][306][307][308][309][310][311] For instance, Girotto et al [311] utilized the spray coating of the hole-transport layer (poly(3,4ethylenedioxythiophene):poly(styrenesulfonate)) (PEDOT:PSS), electron-transport layer (poly(3-hexyl thiophene) (P3HT):C 60derivative (6,6)-phenyl C 61 -butyric acid methyl ester (PCBM) mixture) (P3HT:PCBM) for fabricating highly efficient organic solar cells with a power conversion efficiency of 3.75%. By optimizing the ink formula, the authors were able to deposit thin films with a well-defined thickness (<10 nm) and small surface roughness.…”

Review for Rare-Earth-Modified Perovskite Materials and Optoelectronic Applications

“…There have been many reports about improving the performance of perovskite devices. For example, in the field of perovskite solar cells, various methods have been demonstrated, including tuning the perovskite component proportion, controlling the film quality and crystalline size of perovskite active layer, optimizing the device structure, introducing plasmonic nano-converters, and so on [ 8 , 9 , 10 , 11 ]. Although these methods have boosted the PCE of PSCs, upper threshold value may be hampered for further development.…”

One-pot synthesis of stable and functional hydrophilic CsPbBr3 perovskite quantum dots for “turn-on” fluorescence detection of Mycobacterium tuberculosis

“…CdS, CdSe, and InP), CsPbX 3 QDs have excellent photoelectric properties, such as a high photoluminescence quantum yield, narrow full width at half maximum (FWHM), and tunable emission wavelengths covering the entire visible region (400-760 nm) by changing their composition. 1,2 Therefore, CsPbX 3 QDs are ideal materials for designing optoelectronic devices, including solar cells, 3 photodetectors, 4 light-emitting diodes, 5,6 lasers 7 and so on. Inspired by the excellent optical properties of CsPbX 3 QDs, new fluorescent sensing platforms for biomolecule detection with high sensitivity are pursued.…”
