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…
Disordered Mott-Hubbard Physics in Nanoparticle Solids: Persistent Gap Across the Disorder-localized-to-Mott-localized Transition
Davis Unruh, Alberto Camjayi, Chase Hansen +3
We show that Nanoparticle (NP) solids are an exciting platform to seek new insights into the disordered Mott-Hubbard physics. We developed a "Hierarchical Nanoparticle Transport Si…
Coupling between dynamic magnetic and charge-order correlations in the cuprate superconductor NdCeCuO
E. H. da Silva Neto, M. Minola, B. Yu +14
Charge order has now been observed in several cuprate high-temperature superconductors. We report a resonant inelastic x-ray scattering experiment on the electron-doped cuprate Nd$…
