Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics
(Royal Society of Chemistry, 2018-11)
Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power
conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under
operation ...
Do Capacitance Measurements Reveal Light-Induced Bulk Dielectric Changes in Photovoltaic Perovskites?
(American Chemical Society, 2018-06)
Several studies have identified complex interactions between photogenerated carriers and the crystal lattice in perovskite materials for photovoltaics, which are regarded to have an inherently soft character. Light is known ...
Methylammonium Lead Bromide Perovskite Battery Anodes Reversibly Host High Li-Ion Concentrations
(American Chemical Society, 2017-04)
Ions migrate through the hybrid halide perovskite lattice, allowing for a variety of electrochemical applications as perovskite-based electrodes for batteries. It is still unknown how extrinsic defects such as lithium ions ...
Gold(I) Metallo‐Tweezers for the Recognition of Functionalized Polycyclic Aromatic Hydrocarbons by Combined π–π Stacking and H‐Bonding
(Wiley, 2017)
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 ...
Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer
(Wiley, 2017-08-07)
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 ...
Stability of dye-sensitized solar cells under extended thermal stress
(Royal Society of Chemistry, 2017)
In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising
candidate for low cost energy production due to cost-effective materials and fabrication processes. Arguably,
DSC ...
Platinum-Based Organometallic Folders for the Recognition of Electron-Deficient Aromatic Substrates
(Wiley, 2017-05-29)
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 ...
Origins and mechanisms of hysteresis in organometal halide perovskites
(IOP, 2017-04)
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 ...
A palladium-hinged organometallic square with a perfect-sized cavity for the encapsulation of three heteroguests
(Royal Society of Chemistry, 2019-12-25)
A nanometer-sized tetrapalladium metallosquare with a pyrene-bisimidazolylidene ligand was found to display a perfect-sized cavity for the encapsulation of three heteroguests, enabling the formation of quintuple D–A–D–A–D ...
WO3/BiVO4: impact of charge separation at the timescale of water oxidation
(Royal Society of Chemistry, 2019-01-16)
The four hole oxidation of water has long been considered the kinetic bottleneck for overall solar-driven water splitting, and thus requires the formation of long-lived photogenerated holes to overcome this kinetic barrier. ...
