A Rational Approach to Improve the Overall Performances of Semitransparent Perovskite Solar Cells by Electrode Optical Management
American Chemical Society (2024)Improving the overall characteristics of semitransparent solar cells (STSCs) is a very hard goal, not only because the absorption and the transmission of light through the device are two competitive processes but also ... -
Advances in Storage Batteries, Layered Hybrid Perovskites and Organic Photovoltaics, and Plasma Activated Ammonia Synthesis
American Chemical Society (2021-01-28)The Energy Spotlight in this issue features three articles recently published in ACS Energy Letters. These highlights are presented by our EAB members, Yan Yu, Ivan Mora-Sero ́ ́, and Jason C. Hicks. They have highlighted ... -
An Iron Bis(carbene) Catalyst for Low Overpotential CO2 Electroreduction to CO: Mechanistic Insights from Kinetic Zone Diagrams, Spectroscopy, and Theory
American Chemical Society (2021-12-08)A common challenge in molecular electrocatalysis is the relationship between maximum activity and the overpotential required to reach that rate, with faster catalysts incurring higher overpotentials. This work follows a ... -

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 ... -
Modulating the interaction between gold and TiO2 nanowires for enhanced solar driven photoelectrocatalytic hydrogen generation
Royal Society of Chemistry (2015)The interaction strength of Au nanoparticles with pristine and nitrogen doped TiO2 nanowire surfaces was analysed using density functional theory and their significance in enhancing the solar driven photoelectrocatalyti ... -
Understanding the Improvement in the Stability of a Self-Assembled Multiple-Quantum Well Perovskite Light-Emitting Diode
American Chemical Society (2020-11-07)We fabricate two-dimensional Ruddlesden–Popper layered perovskite films by introducing 1-naphthylmethylamine iodide into the precursor, which forms a self-assembled multiple-quantum well (MQW) structure. Enabling outstanding ... -
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. ...
