Critical transport behavior in quantum dot solids
Zachary Crawford, Adam Goga, Mikael Kovtun +1
Due to recent advances, silicon solar cells are rapidly approaching the Shockley-Queisser limit of 33% efficiency. Quantum Dot (QD) solar cells have the potential to surpass this l…
Hydrogen-induced degradation dynamics in silicon heterojunction solar cells via machine learning
Andrew Diggs, Zitong Zhao, Reza Vatan +5
Among silicon-based solar cells, heterojunction cells hold the world efficiency record. However, their market acceptance is hindered by an initial 0.5\% per year degradation of the…
Full-Spin-Wave-Scaled Finite Element Stochastic Micromagnetism: Mesh-Independent FUSSS LLG Simulations of Ferromagnetic Resonance and Reversal
Harald Oezelt, Luman Qu, Alexander Kovacs +11
In this paper, we address the problem that standard stochastic Landau-Lifshitz-Gilbert (sLLG) simulations typically produce results that show unphysical mesh-size dependence. The r…
From Femtoseconds to Gigaseconds: The SolDeg Platform for the Performance Degradation Analysis of Silicon Heterojunction Solar Cells
Davis Unruh, Reza Vatan Meidanshahi, Chase Hansen +4
Heterojunction Si solar cells exhibit notable performance degradation. We developed the SolDeg platform to model this degradation as electronic defects getting generated by thermal…
Percolative Charge Transport In Binary Nanocrystal Solids
Luman Qu, Davis Unruh, Gergely T. Zimanyi
We simulated electron transport across a binary nanocrystal solid (BNS) of PbSe NCs with diameters of 6.5nm and 5.1nm. We used our Hierarchical Nanoparticle Transport Simulator HIN…
Describing transport in defected nanoparticle solids using a new, hierarchical, simulation tool, TRIDENS
Chase Hansen, Davis Unruh, Miguel Alba +4
The efficiency of nanoparticle (NP) solar cells has grown impressively in recent years, exceeding 16%. However, the carrier mobility in NP solar cells, and in other optoelectronic…
