Experimental study of light scattering from solar cells surfaces
Nádaský, Pavel ; Malina, Radomír (referee) ; Ohlídal, Miloslav (advisor)
This thesis deals with experimental measurement of angular distribution of electromagnetic radiation scattered from solar cells surfaces. The measuring apparatus is the second genaration of a scattermeter. This apparatus has been put into operation within the framework of this thesis. Results of the thesis are materials for numerical simulations aforementioned scattering and quantitative evaluation of scattering of electromagnetic waves from given surfaces.

Design and realization of the device for measurement of light scattering from surfaces of solar cells
Gründling, Vladimír ; Křupka, Ivan (referee) ; Ohlídal, Miloslav (advisor)
The principle of an original instrument for experimental measurement of electromagnetic wave scattering from rough planar surfaces is presented in the diploma theses. A design and realization of the instrument is presented too. The instrument is primarily intended for measurement of angle intensity distribution of light scattered from solar cells surfaces. Owing to a possibility to analyse surfaces with a high level anisotropy of electromagnetic wave scattering it is possible to use the instrument for a study of surfaces with an arbitrary type of the surface roughness.

Flow over a rough surface
Bauer, Petr
We attempt to model a 2D rough surface by computing non-stationary Navier-Stokes ow over a periodic pattern. The solution is obtained by means of _nite element method (FEM). We use non-conforming Crouzeix Raviart elements for velocity and piecewise con- stant elements for pressure. The resulting linear system is solved by multigrid method. We present computational studies of the problem.
