Effect of pressure on the dynamics of iodine defects in MAPI: An atomistic simulation
Rachel Elizabeth Brophy, Movaffaq Kateb, Kristinn Torfason +4
The diffusion of iodine defects has been considered the most important degradation mechanism of methylammonium lead iodine (MAPI) in solar cells. The present study demonstrates the…
Optoelectronic and stability properties of quasi-2D alkylammonium based perovskites
N. Filipoiu, Anca G. Mirea, Sarah Derbali +6
Electronic and stability properties of quasi-2D alkylammonium perovskites are investigated using density functional theory (DFT) calculations and validated experimentally on select…
Capacitive and inductive effects in perovskite solar cells: the different roles of ionic current and ionic charge accumulation
Nicolae Filipoiu, Amanda Teodora Preda, Dragos Victor Anghel +8
Dynamic hysteresis effects have been long known to occur in the J-V characteristics of perovskite solar cells (PSCs), with the ionic migration being identified as the primary facto…
Bistability of the BiOi complex and its implications on evaluating the acceptor removal
C. Besleaga, A. Kuncser, A. Nitescu +3
The dependencies of the BO defect concentration on doping, irradiation fluence and particle type in p-type silicon diodes have been investigated. We evidenced that larg…
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…
Comparison of near-interface traps in AlO/4H-SiC and AlO/SiO/4H-SiC structures
Marc Avice, Ulrike Grossner, Ioana Pintilie +3
Aluminum oxide (Al2O3) has been grown by atomic layer deposition on n-type 4H-SiC with and without a thin silicon dioxide (SiO2) intermediate layer. By means of Capacitance Voltage…
