Quantum dot (QD) solids represent a new type of condensed matter drawing high fundamental and applied interest. confinement in individual QDs, combined with macroscopic scale whole materials, leads to novel exciton charge transfer features that are particularly relevant optoelectronic applications. This Perspective discusses the structure semiconductor QD solids, optical spectral properties, carrier transport, photovoltaic The distance between adjacent nanoparticles surface ligands...
Ion-beam sputtering offers significant benefits in terms of deposition uniformity and pinhole-free thin films without limiting the scalability process. In this work, reactive ion-beam nickel oxide has been developed for hole transporting layer p–i–n perovskite solar cells (PSCs). The process is carried out by oxidation scattered Ni particles with additional post-treatment annealing regimes. Using a rate 1.2 nm/min allowed growth very uniform NiOx coating roughness below 0.5 nm on polished Si...
Nickel oxide (NiO) is one of the most promising and high-performing Hole Transporting Layer (HTL) in inverted perovskite solar cells due to ideal band alignment with absorber, wide gap, high mobility charges. At same time, however, NiO does not provide good contact trap-free junction for hole collection. In this paper, we examine problem by developing a double transport configuration copper iodide (CuI) interlayer efficient surface passivation. Transient photo-current (TPC) measurements...

Hybrid organo-inorganic perovskites are promising for such systems due presence of lead ions in their composition. The electrical properties CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub> single crystals synthesized by method modified crystallization inverse temperature dependence studied. conducted studies allowed us establish applicability obtained...
A novel triphenylamine derivative-linked ionic liquid unit, 1-(6-((4-(bis(4-(thiophen-2-yl)phenyl)amino)benzoyl)oxy)hexyl)-3-methyl-imidazolium tetrafluoroborate (TTPAC6IL-BF4), was designed and synthesized successfully, its corresponding polymer PTTPAC6IL-BF4 obtained by the electropolymerization method. The highest occupied molecular orbital energy band of TTPAC6IL-BF4 is higher onset oxidative potential lower compared with that 6-bromohexyl 4-(bis(4-(thiophen-2-yl)phenyl)amino) benzoate...
Transparent-to-colored electrochromic devices exhibit promising application prospects and have gained popularity. Herein, two triphenylamine derivatives TPA-OCH3 TPA-CN with styryl moieties different donor or acceptor units were designed synthesized to further prepare solvent-resistant thermally cross-linking polymer P(TPA-OCH3) P(TPA-CN) without any additional initiator. possess pairs of redox peaks, shows a lower onset oxidation potential compared because the pendent unit. Correspondingly,...
