Gain-Layer Project
Niels G. Sorgenfrei, Anna Rita Altamura, Cristina Besleaga +18
Gain-layer degradation from exposure to radiation limits the use of Low-Gain Avalanche Diodes (LGADs) in high energy particle physics detector experiments. Proper understanding of…
Superstrate structured SbS thin-film solar cells by magnetron sputtering of Sb and post-sulfurization
Evgeniia Gilshtein, Harshvardhan Maheshkant Gupta, Andrea Maria Pierri Enevoldsen +3
We report on the fabrication and optimization of semi-transparent antimony sulfide (SbS) thin-film solar cells in a superstrate configuration, using RF magnetron sputtering…
Electron transporting bilayers for perovskite solar cells: spray coating deposition of c-TiO2/m-SnO2-quantum dots
Anca G. Mirea, Ioana D. Vlaicu, Sarah Derbali +12
Herein we present a comparative study among different mesoporous electron transporter layers (ETLs), namely nanometric m-TiO2, m-SnO2 and m-SnO2 quantum dots (QDs), deposited by sp…
Impact of interface defects on the band alignment and performance of TiO/MAPI/CuO perovskite solar cells
Nicolae Filipoiu, Marina Cuzminschi, Mihaela Cosinschi +9
Optimizing the interfaces in perovskite solar cells (PSCs) is essential for enhancing their performance, improving their stability, and making them commercially viable for large-sc…
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…
The hysteresis-free behavior of perovskite solar cells from the perspective of the measurement conditions
George Alexandru Nemnes, Cristina Besleaga, Andrei Gabriel Tomulescu +5
We investigate in how far the hysteresis-free behavior of perovskite solar cells can be reproduced using particular pre-conditioning and measurement conditions. As there are curren…
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…
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…
