abstract = {The influence of a retro-reflective texture cover on light
in-coupling and light-trapping in thin film silicon solar
cells is investigated. The texture cover is applied to the
front glass of the cell and leads to a reflectance as low as
$r3\%$ by reducing the reflection at the air/glass interface
and indirectly also reducing the reflections from the
internal interfaces. For weakly absorbed light in the long
wavelength range, the texture also enhances the
light-trapping in the solar cell. We demonstrate an increase
of the short circuit current density of exemplary
investigated thin film silicon tandem solar cells by up to
0.95mAcm2 and of the conversion efficiency by up to
$0.74\%(absolute).$ For a planar microcrystalline solar
cell, the enhancement of light-trapping was determined from
the reduced reflection in the long wavelength range to be up
to $17\%,$ leading to an increase of the external quantum
efficiency of up to $12\%.$},
