abstract = {Light trapping in thin-film silicon solar cell arising from
randomly textured ZnO front contact layers is investigated
in the optical near-field experimentally and theoretically.
The experimental data are obtained from near-field scanning
optical microscopy, theoretical data are calculated using
rigorous diffraction theory. The surface of the randomly
textured ZnO consists of statistically distributed craters
with different shapes. Along the rims of the craters light
localizations are found. Photon jets emerge from the
vertices of the surface profile. From the theoretical study,
the local absorption enhancement is calculated. The results
provide important insight into the local effects of light
trapping in thin-film optoelectronic devices and strategies
for optimizing the external quantum efficiency in thin-film
silicon solar cells are discussed. (C) 2008 WILEY-VCH Verlag
