Self-Assembly of Di-N-Heterocyclic Carbene-Gold-Adorned Corannulenes on C60
The deprotonation of a corannulene-based bisazolium salt allowed the preparation of a corannulene-based NHC di-AuI complex. The prepared di-AuI-complex was tested in the recognition of fullerene-C60, demonstrating good ...
Tunable Open Circuit Voltage by Engineering Inorganic Cesium Lead Bromide/Iodide Perovskite Solar Cells
(Nature Publishing Group, 2018)
Perovskite solar cells based on series of inorganic cesium lead bromide and iodide mixture, CsPbBr3-xI x , where x varies between 0, 0.1, 0.2, and 0.3 molar ratio were synthesized by two step-sequential deposition at ambient ...
Single Step Deposition of an Interacting Layer of Perovskite Matrix with Embedded Quantum Dots
(Royal Society of Chemistry, 2016)
Hybrid lead halide perovskite (PS) derivatives have emerged as very promising materials for the development of optoelectronic devices in the last few years. At the same time, inorganic nanocrystals with quantum confinement ...
Evaluation of multiple cation/anion perovskite solar cells through life cycle assessment
(Royal Society of Chemistry, 2018)
After the great initiation of perovskite as a photovoltaic material, laboratory efficiencies similar to other photovoltaic technologies already commercialised have been reached. Consequently, recent research interests on ...
Cobalt Hexacyanoferrate on BiVO4 Photoanodes for Robust Water Splitting
The efficient integration of photoactive and catalytic materials is key to promoting photoelectrochemical water splitting as a sustainable energy technology built on solar power. Here, we report highly stable water splitting ...
Platinum-Based Organometallic Folders for the Recognition of Electron-Deficient Aromatic Substrates
A series of platinum complexes with cis-oriented polyaromatic N-heterocyclic carbene ligands were prepared and characterized. The relative disposition of the polyaromatic ligands about the metal cause these compounds to ...
Perovskite solar cells: a brief introduction and some remarks
(Sociedad Cubana de Física, 2017)
The spectacular and unprecedented rise of so-called perovskite solar cells (PSCs) in conversion efficiency with low-cost manufacturing processes has grabbed the attention of the scientific community ...
Gold(I) Metallo‐Tweezers for the Recognition of Functionalized Polycyclic Aromatic Hydrocarbons by Combined π–π Stacking and H‐Bonding
Two gold(I)‐based metallo‐tweezers with bis(Au−NHC) pincers and a carbazole connector have been obtained and used for the recognition of polycyclic aromatic hydrocarbons (PAHs). In the case of the tweezer with pyrene–NHC ...
Origins and mechanisms of hysteresis in organometal halide perovskites
Inorganic–organic halide organometal perovskites, such as CH3NH3PbI3 and CsPbI3, etc, have been an unprecedented rising star in the field of photovoltaics since 2009, owing to their exceptionally high power conversion ...
Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer
A combination of self-complementary pi-pi-stacking interactions and metallophilic interactions triggered the self-assembly of a new digold(I) metallo-tweezer in the presence of several types of M+ ions. Titrations by ...
