Welcoming the First Decade of Perovskite Solar Cells
(Wiley, 2019-09-02)
The swift emergence of perovskite solar cells (PSCs) is a “miracle” development in the history of photovoltaics. Since Miyasaka and co‐workers (Toin University of Yokohama, Japan) reported the first use of halide perovskites ...
Photocatalytic and Photoelectrochemical Degradation of Organic Compounds with All-Inorganic Metal Halide Perovskite Quantum Dots
(American Chemical Society, 2019-01)
Inspired by the outstanding optoelectronic properties reported for all-inorganic halide perovskite quantum dots (QDs), we have evaluated the potential of these materials toward the photocatalytic and photoelectrochemical ...
Properties of Contact and Bulk Impedances in Hybrid Lead Halide Perovskite Solar Cells Including Inductive Loop Elements
(American Chemical Society, 2016)
Impedance spectroscopy offers access to all the different electronic and ionic processes taking place simultaneously in an operating solar cell. To date, its use on perovskite solar cells has been challenging because of ...
Light-Induced Space-Charge Accumulation Zone as Photovoltaic Mechanism in Perovskite Solar Cells
(American Chemical Society, 2016)
We fabricated formamidinium lead iodide perovskite solar cell for analysis of the photovoltaic mechanism based on the interpretation of the capacitance variation under illumination. It was shown that the low-frequency ...
Interfacial Passivation of Perovskite Solar Cells by Reactive Ion Scavengers
(American Chemical Society, 2021-02-22)
Lead halide perovskites suffer from uncontrolled ion migration and the interactions at the external contacts play a fundamental role in the hysteretic response and performance degradation kinetics. In this work, we passivate ...
Abiotic depletion and the potential risk to the supply of cesium
(Elsevier, 2020-10)
The petroleum exploration industry is the largest end user of cesium where it is employed in oil well drilling fluid. It has recently been broadly reported that the inclusion of cesium into perovskite for photovoltaics and ...
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 ...
Multicomponent Approach for Stable Methylammonium-Free Tin–Lead Perovskite Solar Cells
(American Chemical Society, 2024-02-09)
Mixed tin–lead perovskites suffer from several degradation pathways that hinder their effective implementation in tandem photovoltaic technologies. The main challenge involves removing the thermally unstable methylammonium ...
Solvent-Mediated Structural Evolution Mechanism from Cs4PbBr6 to CsPbBr3 Crystals
(MDPI, 2021-07-05)
The study of the solvent-mediated structural evolution mechanism of the Cs4PbBr6 powders prepared using the solvothermal method is presented. The Cs4PbBr6 powders with a rhombohedral structure and an intense green emission ...
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 ...
