Strategies for enhancing conductivity of colloidal nanocrystals and their photoelectronic applications

High-sensitivity hybrid PbSe/ITZO thin film-based phototransistor detecting from 2100 to 2500 nm near-infrared illumination

“…Upon the deposition of a single layer, scattered QD islands with barely any connection between them were observed to form once the ligand exchange step was performed. The decreased volume of solid-phase exchange (as a consequence of sizeable initial ligand replacement with a smaller molecule) tends to form cracks and voids in the film [23]. Additional layers are needed for filling in the gaps and to achieve a uniform layer.…”

Cu2O/Cu2S microstructure regulation towards high efficiency photocatalytic hydrogen production and its theoretical mechanism analysis

“…The strategy of heterojunction formation has been shown to be effective in facilitating the separation and transport of catalyst charges. 13–38 S. Mann et al 39 used Cu(CH 3 COO) 2 ·H 2 O as a precursor, and the CuO/Cu 2 O microspheres synthesized by a hydrothermal method without a template and additives showed better photocatalytic activity under visible light. Zhao et al 40 introduced MoS 2 nanosheets onto the surface of Cu 2 O nanoparticles, which reduced the proton reduction overpotential of the electrochemical reaction, and inhibited the photo-induced corrosion.…”

Recent progress of transparent conductive electrodes in the construction of efficient flexible organic solar cells

“…and plastic. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Although metal foils have good mechanical ductility, electrical conductivity, and high temperature resistance, the active layer of solar cells can be prepared at high temperature in the future. However, due to the opacity of the metal foil, the light absorption loss is very serious, which puts forward more stringent conditions for manufacturing process.…”
