How measurement protocols influence the dynamic J-V characteristics of perovskite solar cells: theory and experiment
G. A. Nemnes, Cristina Besleaga, A. G. Tomulescu +4
The dynamic effects observed in the J-V measurements represent one important hallmark in the behavior of the perovskite solar cells. Proper measurement protocols (MPs) should be em…
Polarization branches and optimization calculation strategy applied to ABO3 ferroelectrics
Lucian D. Filip, Neculai Plugaru
Berry phase polarization calculations have been investigated for several ferroelectric materials from the point of view of practical calculations. It was shown that interpretation…
Normal and inverted hysteresis in perovskite solar cells
George Alexandru Nemnes, Cristina Besleaga, Viorica Stancu +6
Hysteretic effects are investigated in perovskite solar cells in the standard FTO/TiO/CHNHPbICl/spiro-OMeTAD/Au configuration. We report normal (NH) and inv…
Dynamic electrical behavior of halide perovskite based solar cells
George Alexandru Nemnes, Cristina Besleaga, Andrei Gabriel Tomulescu +4
A dynamic electrical model is introduced to investigate the hysteretic effects in the I-V characteristics of perovskite based solar cells. By making a simple ansatz for the polariz…
Epitaxial thin films of the multiferroic double perovskite Bi2FeCrO6 grown on (100)-oriented SrTiO3 substrates: Growth, characterization, and optimization
Riad Nechache, Catalin Harnagea, Louis-Philippe Carignan +7
The influence of the deposition pressure PO2 and substrate temperature TS during the growth of Bi2FeCrO6 thin films grown by pulsed laser deposition has been investigated. It is fo…
Intrinsic ferroelectric properties of strained tetragonal PbZr0.2Ti0.8O3 obtained on layer-by-layer grown, defect-free single crystalline films
Ionela Vrejoiu, Gwenael Le Rhun, Lucian Pintilie +3
PbZrxTi1-xO3 (PZT) is one of the technologically most important ferroelectric materials. Bulk single-domain single crystals of PZT have never been synthesized for a significant com…
