A New Approach to Characterize Charge Transport and Hysteresis in Perovskite Solar Cells
Gabriel L. Nogueira, Victor Lopez-Richard, Luiz A. Meneghetti +2
Perovskite solar cells (PSCs) have emerged as a promising photovoltaic technology, already achieving efficiencies surpassing 25%. However, effects such as hysteresis are commonly o…
From Memory Traces to Surface Chemistry: Decoding REDOX Reactions
Ana Luiza Costa Silva, Rafael Schio Wengenroth Silva, Lucas Augusto Moisés +4
Gas and moisture sensing devices leveraging the resistive switching effect in transition metal oxide memristors promise to revolutionize next-generation, nano-scaled, cost-effectiv…
Microscopic Modeling of Polarization Dynamics in Leaky Dielectrics: Insights into Ferroelectric-Like Behavior
Igor Ricardo Filgueira e Silva, Ovidiu Lipan, Fabian Hartmann +2
Based on a microscopic model of nonequilibrium carrier generation in a leaky dielectric, we analytically derive hysteresis loops for the dielectric response of non-polar, non-ferro…
