Influence of Molecular Polarizability on the Active Layer of Organic Photovoltaic Cells: A case study of Poly(3-hexylthiophene)
(2013-05-23)
The complexity of the microstructure of the active layer in organic photo-voltaics (OPVs) poses a unique challenge in improving the efficiency of OPV devices. Molecular dynamics (MD) simulation provides a direct route ...
Femtosecond Laser Surface Texturing of Materials for Various Applications
(2013-04-23)
Femtosecond lasers represent an electromagnetic field with field intensities approaching and even exceeding atomic binding field. When irradiated on a target, the material responses change from linear to nonlinear within ...
The Design of an On-Chip Silicon Photonic Diode
(2013-05-28)
This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on ...
Nonlinear Effects In Flow In Porous Duct
(2013-05-28)
In general, it is assumed in some non viscous flows that the flow velocity is constant at a cross-section. In this thesis, If we impose more realistic boundary conditions by, for example, introducing viscosity,and suction ...
