Multiscale modeling of solar cells with interface phenomena

Visual Modeling and Simulation of Multiscale Phenomena

RAHUL NARAIN: Visual Modeling and Simulation of Multiscale Phenomena (Under the direction of Ming C. Lin) Many large-scale systems such as human crowds, fluids, and granular materials exhibit complicated motion at many different scales, from a characteristic global behavior to important small-scale detail. Such multiscale systems are computationally expensive for traditional simulation techniqu...

Modeling Solar Atmospheric Phenomena with AtomDB and PyAtomDB

Taking advantage of the modeling tools made available by PyAtomDB Foster(2015), we evaluated the atomic impact of solar phenomena. In particular, the atomic effects of coronal mass ejections (CME). Intitially, we perform modifications to the canonical SunNEI code N.A.Murphy et al.(2011) in order to include non-equilibrium ionization (NEI) processes that occur in the CME modeled in SunNEI. The m...

MultiScale Modeling of Physical Phenomena: Adaptive Control of Models

It is common knowledge that the accuracy with which computer simulations can depict physical events depends strongly on the choice of the mathematical model of the events. Perhaps less appreciated is the notion that the error due to modeling can be defined, estimated, and used adaptively to control modeling error, provided one accepts the existence of a base model that can serve as a datum with...

Application of Au@SiO2 Plasmonic Nanoparticles at Interface of TiO2 Mesoporous Layers in Perovskite Solar Cells

To investigate the plasmonic effect in perovskite solar cells, the effect of depositing Au@SiO2 nanoparticles on the top and the bottom of mesoporous TiO2 layers was studied. First, Au@SiO2 nanoparticles were synthesized. The particles were then deposited at the different interfaces of mesoporous TiO2 layers. Although the two structures show approximately similar optical absorption, only cells ...
