Effects of Frequency Dependence of the External Quantum Efficiency of Perovskite Solar Cells
(American Chemical Society, 2018-05)
Perovskite solar cells are known to show very long response time scales, on the order of milliseconds to seconds. This generates considerable doubt over the validity of the measured external quantum efficiency (EQE) and ...
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 ...
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, ...
Homeopathic Perovskite Solar Cells: Effect of Humidity during Fabrication on the Performance and Stability of the Device
(American Chemical Society, 2018-02)
Rapid degradation in humid environments is a major drawback of methylammonium lead iodide (CH3NH3PbI3), which is the archetypical component of perovskite solar cells. In this work, we have investigated the aging and ...
α-FAPbI3 powder presynthesized by microwave irradiation for photovoltaic applications
(Elsevier, 2022-12-10)
The development of up-scalable and high-throughput methodologies to fabricate high-efficiency lead halide perovskite solar cells (PSCs) based on α-phase formamidinium lead iodide (FAPbI3) is one of the main challenges of ...
