Several application fields can benefit from solar-hydrogen technologies <italic>via</italic> specific short-term and long-term pathways.
The recent development of phase transfer ligand exchange methods for PbS quantum dots (QD) has enhanced the performance solar cells and greatly simplified complexity film deposition. However, dispersions QDs (inks) used fabrication often suffer from colloidal instability, which hinders large-scale cell production. In addition, wasteful spin-coating method is still main technique deposition QD layer in cells. Here, we report a strategy scalable highly stable inks. By dispersing capped with...
Abstract The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities advance the sustainability quality our lives—e.g. via smart homes, cities, healthcare, logistics, Industry 4.0, precision agriculture. realization full potential these applications critically depends on availability easy-to-make, low-cost sensor technologies. Sensors based printable electronic materials offer ideal...
Capping colloidal quantum dots (CQDs) with atomic ligands is a powerful approach to tune their properties and improve the charge carrier transport in CQD solids. Efficient passivation of surface, which can be achieved halide ligands, crucial for application optoelectronic devices. Heavier halides, i.e., I- Br-, have been thoroughly studied as capping last years, but fluoride ions has not received sufficient consideration. In this work, effective coating PbS CQDs demonstrated compared results...
Phase-transfer exchange of pristine organic ligands for inorganic ones is essential the integration colloidal quantum dots (CQDs) in optoelectronic devices. This method results a dispersion (ink) which can be directly deposited by various solution-processable techniques to fabricate conductive films. For PbS CQDs capped with methylammonium lead iodide (MAPbI3), most commonly employed solvent butylamine, enables only short-term (hours) stability and thus brings concerns on possibility...
PbS colloidal quantum dots (CQDs) are versatile building blocks for bottom-up fabrication of various optoelectronic devices. The transport properties thin films this class materials depend on the size CQDs, their surface ligands, and stoichiometry. most common synthetic methods yield CQDs with an excess Pb atoms, which induces n-type in CQD films. In work, we developed a new synthesis, offers S-rich CQDs. Thanks to sufficient stability nonpolar solvents, established protocol integration...
Abstract Light‐emitting field‐effect transistors (LEFETs) are emerging optoelectronic devices able to display simultaneously electrical switching as and electroluminescence emission light emitting diodes. Lead chalcogenide colloidal quantum dots (CQDs) allow achieving in a very broad spectral range, covering the near‐infrared (NIR) short‐wavelength infrared (SWIR) regions, which cannot be reached with other solution‐processable materials. Therefore, use of lead CQDs active layer LEFETs opens...
Thanks to their broadly tunable bandgap and strong absorption, colloidal lead chalcogenide quantum dots (QDs) are highly appealing as solution‐processable active layers for third‐generation solar cells. However, the modest reproducibility of this kind cell is a pertinent issue, which inhibits exploitation material class in optoelectronics. This issue not necessarily imputable layer but may originate from different constituents device structure. Herein, deposition TiO 2 electron transport...
Metal halide perovskite shelled quantum dot solids have recently emerged as an interesting class of solution-processable materials that possess the desirable electronic properties both dots and perovskites. Recent reports shown lead sulfide (PbS QDs) with ligand-shells can be successfully utilized in (opto)electronic devices such solar cells, photoconductors, field-effect transistors (FETs), a development attributed to compatibility lattice parameters between PbS certain metal perovskites...
