to improve photovoltaic efficiency. In this model we show that the material can
have three successive incident ray absorptions instead of two currently, by varying
the incidence angle, the aperture between the summit of two neighboring pyramids
and their height. This study concerns in particular the photovoltaic parameters
such as the spectral response, the absorption coefficient and the generation rate.
This model was checked for angles varying between 54 and 60° and for pyramid
heights between 5 and 10 μm. For these values of incidence angle, the apertures
between the summits of two neighboring pyramids varied respectively from 14.54
to 11.54 μm for a pyramid height of 10 μm.]]>Goetzberger, A., C. Hebling and H.W. Schock,2003Grasso, C., A. Goossens and M. Burgelman,2005Moller, H.J., C. Funke, M. Rinio and S. Scholz,2005Shah, A.V., J. Meier, E. Vallat-Sauvain, N. Wyrsch, U. Kroll, C. Droz and U. Graf,2003
