Impact of Capacitive Effect and Ion Migration on the Hysteretic Behavior of Perovskite Solar Cells
(American Chemical Society, 2015-11)
In the past five years, perovskite solar cells (PSCs) based on organometal halide perovskite have exhibited extraordinary photovoltaic (PV) performance. However, the PV measurements of PSCs have been widely recognized to ...
Distinction between capacitive and noncapacitive hysteretic currents in operation and degradation of perovskite solar cells
(American Chemical Society, 2016)
Perovskite solar cells suffer from significant performance distortions under working conditions, usually known by the generic label of hysteretic effects. A classification of the fluctuations associated with current–voltage ...
Quantification of Ionic Diffusion in Lead Halide Perovskite Single Crystals
(American Chemical Society, 2018)
Lead halide perovskites are mixed electronic–ionic semiconductors that have recently revolutionized the photovoltaics field. The physical characterization of the ionic conductivity has been rather elusive because of the ...
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, ...
