Interpretation of the Recombination Lifetime in Halide Perovskite Devices by Correlated Techniques
(American Chemical Society, 2022-08-03)
The recombination lifetime is a central quantity of optoelectronic devices, as it controls properties such as the open-circuit voltage and light emission rates. Recently, the lifetime properties of halide perovskite devices ...
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 ...
Unique Curve for the Radiative Photovoltage Deficit Caused by the Urbach Tail
(American Chemical Society, 2021-08-12)
The photovoltage Voc of high-performance solar cells such as GaAs
and metal halide perovskites is affected by the exponential Urbach tail in the
absorption spectrum, with an energy parameter EU. It has been observed ...
Insights into the past and future of Janus-di-N-heterocyclic carbenes
(2021-07-19)
Janus di-N-heterocyclic carbene (NHC) ligands are a subclass of poly-NHCs that feature coordination to two transition metals in a facially opposed manner. The combination of the structural features of Janus type ligands, ...
The contribution of NMR spectroscopy in understanding perovskite stabilization phenomena
(MDPI, 2021-08-08)
Although it has been exploited since the late 1900s to study hybrid perovskite materials, nuclear magnetic resonance (NMR) spectroscopy has only recently received extraordinary research attention in this field. This very ...
Recent Developments in Process Digitalisation for Advanced Nanomaterial Syntheses
(Wiley, 2022-12-01)
Digitalisation and industry 4.0 are set to profoundly change the way chemical and materials discovery and development work. The integration of multiple enabling technologies such as flow synthesis, automation, analytics, ...
Sustainable oxygen evolution electrocatalysis in aqueous 1 M H2SO4 with earth abundant nanostructured Co3O4
(Nature Research, 2022-07-27)
Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) able to work in acidic working conditions are elusive. While many first-row transition metal oxides are competitive in alkaline media, most of them ...
Mechanistic studies of a lipase unveil effect of pH on hydrolysis products of small PET modules
(Springer Nature, 2023-06-15)
Biocatalysis is a key technology enabling plastic recycling. However, despite advances done in the development of plastic-degrading enzymes, the molecular mechanisms that govern their catalytic performance are poorly ...
Interfacial Mechanism for Efficient Resistive Switching in Ruddlesden-Popper Perovskites for Non-volatile Memories
(American Chemical Society, 2020-01-16)
Ion migration, one origin of current–voltage hysteresis, is the bane of halide perovskite optoelectronics. Herein, we leverage this unwelcome trait to unlock new opportunities for resistive switching using layered ...
