Abstract Lead sulfide colloidal quantum dot solar cells (CQDSCs), the next generation of photovoltaics, are hampered by non‐radiative recombination induced defects and an electron‐hole extraction imbalance. CQDSCs have three interfaces: CQD/CQD, electron transport layer (ETL)/CQD, CQD/hole (HTL), modifying one these interfaces does not fix problem stated above. Here, coordinated control passivation in PbS presented it is shown that synergistic effects may improve charge carrier balance...
A novel nanostructured catalyst of platinum nanoparticles supported on 5,10,15,20-tetrakis(1-methyl-4-pyridinio)porphyrin tetra(p-toluenesulfonate) (TMPyP) functionalized graphene (TMPyP-graphene) is synthesized by the hydrothermal polyol process. The as-synthesized nanocomposites are characterized Fourier transform infrared (FTIR) spectroscopy, UV-vis absorption Raman X-ray diffraction (XRD), transmission electron microscopy (TEM), photoelectron spectroscopy (XPS) and electrochemical tests....
For the current passivation strategy, pure iodine during solid-state ligand exchange (SSE) cannot completely passivate entire surface of PbS colloidal quantum dots (CQDs). Here, a simple stepwise strategy is proposed based on postpassivation CQD films with halogen (Cl, Br, or I) after through SSE. This could compensate for missing ligands caused by polar environment Thus, both electron- and hole-trapping states are greatly reduced, charge transport in film significantly improved. The...
In Mg-doped ZnO/PbS QDHSCs, a spike structure is formed between the QDs and “electron acceptor”, which improved charge collection efficiency.
Phase-stable CsSnx Pb1-x I3 perovskite quantum dots (QDs) hold great promise for optoelectronic applications owing to their strong response in the near-infrared region. Unfortunately, optimal utilization of potential is limited by severe photoluminescence (PL) quenching, leading extremely low yields (QYs) approximately 0.3 %. The ultra-low sodium (Na) doping presented herein found be effective improving PL QYs these alloyed QDs without alerting favourable electronic structure. X-ray...
Abstract Nowadays, the extensively used lead sulfide (PbS) quantum dot (QD) hole transport layer (HTL) relies on layer‐by‐layer method to replace long chain oleic acid (OA) ligands with short 1,2‐ethanedithiol (EDT) for preparation. However, inevitable significant volume shrinkage caused by this traditional will result in undesired cracks and disordered QD arrangement film, along adverse increased defect density inhomogeneous energy landscape. To solve problem, a novel EDT passivated PbS...
A novel strategy in DESs for the fabrication of MWCNTs-supported PdSn alloy nanostructures is reported. The prepared PdSn/MWCNT shows remarkably improved electrocatalytic performance towards formic acid oxidation reaction.
