Perovskite semiconductors for photoelectrochemical water splitting applications
(Elsevier, 2017-04)
Perovskite oxide semiconductors have been used as efficient electrocatalysts for electrochemical reactions using an external applied bias. The review describes the different alternatives to use perovskite materials as ...
Inductive Loop in the Impedance Response of Perovskite Solar Cells Explained by Surface Polarization Model
(American Chemical Society, 2017-03)
The analysis of perovskite solar cells by impedance spectroscopy has provided a rich variety of behaviors that demand adequate interpretation. Two main features have been reported: First, different impedance spectral arcs ...
Theory of Light-Modulated Emission Spectroscopy
(American Chemical Society, 2017-07)
Perovskite solar cells and fluorescent collectors formed by a dispersion of quantum dots in a transparent solid are paradigmatic devices for photon capture and utilization that involve the coupling of photon displacement, ...
In the Limelight: Perspective Collections on Perovskites
(American Chemical Society, 2017-08)
In our inaugural “ In the Limelight ” Viewpoint, we revisited five high-impact papers that were published in The Journal of Physical Chemistry Letters ( JPC Letters ) in 2014, and we noted that four of the five were written ...
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 ...
Surface Polarization Model for the Dynamic Hysteresis of Perovskite Solar Cells
(American Chemical Society, 2017-02)
The dynamic hysteresis of perovskite solar cells consists of the occurrence of significant deviations of the current density–voltage curve shapes depending on the specific conditions of measurement such as starting voltage, ...
Formation Criteria of High Efficiency Perovskite Solar Cells in Ambient Conditions
(Royal Society of Chemistry, 2017)
The field of lead halide perovskites for solar cell applications has recently reported impressive power conversion (PCE) above 22 % using complex mixed cation formulations. Very importantly, highest PCE have been obtained ...
