Ray Tracing Simulations of Reflections on Textured Solar Cells
lundi 2 février 2015, par
My research activities since the beginning of 2012 concern the modelling of the reflections on pyramidal textures for silicon solar cells. I have developed a 3D ray tracing program which can compute the reflectivity on a textured surface.
What it can do
any azimuth angle,
any altitude angle,
any wavelength in the [0.28 ; 1.0] µm range,
any light polarisation (including unpolarised light).
Multilayer Anti-Reflection Coating.
Limitations of the current version (RAY3Dv3)
details of the texture must be quite greater than the light wavelength (geometric optics approximation),
the surface must be representable by a 
continuous function,
transmitted rays are considered totally absorbed by silicon (which is false above the 1.0-µm wavelength),
only two layers + ARC can be modelled (air+ARC+semiconductor).
