Tuning optical/electrical properties of 2D/3D perovskite by the inclusion of aromatic cation
(Royal Society of Chemistry, 2018)
The employment of bulky aliphatic cations in the manufacture of moisture-stable materials has triggered
the development and application of 2D/3D perovskites as sensitizers in moisture-stable solar cells.
Although it is ...
Discerning recombination mechanisms and ideality factors through impedance analysis of high-efficiency perovskite solar cells
(Elsevier, 2018)
The ubiquitous hysteresis in the current-voltage characteristic of perovskite solar cells (PSCs) interferes in a
proper determination of the diode ideality factor (n), a key parameter commonly adopted to analyze recombination ...
Tripodal halogen bonding iodo-azolium receptors for anion recognition
(Royal Society of Chemistry, 2017)
The synthesis, characterization and anion binding properties of 1,3,5-tri-substituted benzene platform-based tripodal receptors containing halogen bonding (XB) iodo-imidazolium and iodo-triazolium motifs, and hydrogen ...
Combining Modulated Techniques for the Analysis of Photosensitive Devices
(Wiley-VCH GmbH, 2021-09-03)
Small-perturbation techniques such as impedance spectroscopy (IS), inten-sity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are useful tools to characterize and model ...
A Rigid Trigonal‐Prismatic Hexagold Metallocage That Behaves as a Coronene Trap
(Wiley, 2019-05-13)
A trigonal‐prismatic hexagold cage was obtained by combining a triphenylene‐tris(N‐heterocyclic carbene) ligand and a carbazolyl‐bis(alkynyl) linker. The metallocage has a slot‐like cavity with a volume of about 300 Å3. ...
A Size‐Flexible Organometallic Box for the Encapsulation of Fullerenes
(Wiley, 2019-04-19)
A palladium‐cornered molecular square with four pyrene‐bis(imidazolylidene) bridging ligands is reported. This metallo‐polygon can encapsulate C60 and C70. The X‐ray diffraction structures of the empty cage as well as the ...
Hole-induced polymerized interfacial film of polythiophene as co-sensitizer and back-electron injection barrier layer in dye-sensitized TiO2 nanotube array
(Elsevier, 2019-04)
In this work, we demonstrate that an ultra-thin film of polythiophene deposited interfacially via hole-induced polymerization on the surface of dye-sensitized TiO2 nanotube array acts as co-sensitizer, and hinders back-electron ...
Effect of Light Illumination on Mixed Halide Lead Perovskites: Reversible or Irreversible Transformation
(American Chemical Society, 2018)
One intriguing aspect of mixed halide lead perovskites (e.g., CH3NH3PbBrxI3–x) is halide ion segregation when subjected to visible illumination, but this aspect gives rise to the concerns regarding the influence of halide ...
Recent insights for achieving mixed halide perovskites without halide segregation
(Elsevier, 2018-10)
The incorporation of halide perovskites in optoelectronics has provided a fast advance in the fabrication of new sensitizers with a balanced light-harvesting, free carrier transportation, and a progressive overcoming of ...
Effect of Environmental Humidity on the Electrical Properties of Lead Halide Perovskites
(ACS, 2018-12)
In large quantities, water is detrimental to lead halide perovskite solar cells, mainly because of the decomposition of the perovskite layer. In contrast, the presence of small quantities of water has been observed to play ...
